An active electronic device used extensively in solid-state electronic circuits. Today, op amps are used as general analog build in g. However, in tegrators, differentiators, logarithmic. Many uses. The goals of this section are to summarize op amp theory and to highlight in formation. Op amps are transistor circuits fabricated us in g a variety of semiconductor processes,.

Some operat in g. These factors need to be considered when select in g components to. This application would best be served with an op amp with a very high in put. More recent trends in op amp design have been. As a class of devices, op amps require a relatively low operat in g current. The in put impedance of an ideal op amp is in f in ite, which would result in the. In reality, while the in put. This characteristic. The highest in put impedance is provided by op amps fabricated with.

The schematic symbol and simplified model of an op amp are shown in Figure. A central operat in g pr in ciple of negative feedback is that an op amp will attempt. This pr in ciple applies to. In its simplest form,. However, diodes and capacitors are frequently used in the feedback loop to.

An op amp can be configured to operate as an in vert in g or non- in vert in g voltage. In the in vert in g mode Figure , a signal is connected to. The feedback loop acts to ma in ta in. In non- in vert in g mode Figure , no phase shift in g occurs. Ga in A can. The circuit in Figure can be further simplified by remov in g R 2.

In this case, the circuit becomes a high in put impedance voltage. Two terms that appear frequently in discussions of analog in puts are normal. The effects of normal mode. However, it is usually best to. Both in puts see the. As mentioned previously, an op amp amplifies the difference in. The degree of this rejection is called Common Mode.

If each ground po in t is not a true, low impedance path to ground, a voltage. For in stance,. What has happened is that the in puts gradually. The solution is to in stall a resistor R between in put high or in put low. The terms s in gle-ended and differential are usually used to describe an amplifier. A s in gle-ended signal is one referenced to 0V. The signal. A differential signal requires a m in imum of two conductors.

These terms can apply to in puts as well as outputs. A bipolar signal. The ma in benefit of us in g a unipolar range for. The available number. A differential in put will usually offer better noise immunity than a s in gle-ended. This is especially important in systems that take data from a number of.

The two circuits of. Passive filters are relatively simple circuits. Active filters can provide more aggressive filter in g. However, active filters are more complex in design,. Bessel, Butterworth, Chebyshev,. Passive filters. However, active filters can exhibit r in g in g, phase delay, ripple, distortion, loss,. Many data acquisition processes in volve digital signals that are either on or off,. This is in contrast to analog signals where the signal voltage.

Conversely, a digital signal is a 1-bit phenomenon;. Normally, an in tegrated circuit. For more in formation on this topic, consult a text such as the TTL. Note in Figure that the various types of digital gates can be subdivided. A non- in vert in g gate produces a logic. Also note that versions of the in vert in g and non- in vert in g gates exist. The in vert in g version is simply called an in verter,. The rema in der of this discussion on gates concentrates on how to control in dividual.

The type of semiconductor process used to fabricate a digital gate determ in es. The usual method for activat in g a digital in put is to connect the in put to ground. This process is. Note that a typical digital output can usually s in k enough current. The term for this. Exceed in g the recommended fan-out can result in unreliable.

Similarly, mix in g different logic families can. The voltages and current levels correspond in g to logic 1 and logic 0 for TTL. New er implementations. For TTL, note that the in put range is neither symmetrical nor cont in uous. These are discussed elsewhere in this book. Because of its design, a TTL output is effective at s in k in g current to ground to.

However, sufficient variation exists in the design of TTL output. Some TTL. Although TTL logic was an early development in digital in tegrated circuitry,. TTL can. These optimizations. Low Power. CMOS technology is used in l in ear as well as digital devices, and.

The current s in k. An analog in put. The follow in g list summarizes. Specialized analog in put boards may depart from this description, with multiple. Three of the most important specifications in volved in choos in g an analog in put.

The ideal. This is, of course, technically. The analog in put board requires 1—2V of headroom, limit in g. This is, in fact, a very common in put. Stand-alone in struments. This represents. For example, an 8-bit converter can output to b in ary.

This corresponds to 28 or discrete steps. The method for calculat in g. In the case of each converter range shown in Table , the. These observations apply more to plug- in. In comparison, ga in errors of 0. This observation can apply to stand-alone in struments as well. Total error figures for a specific measurement situation depend on the in put.

The key to specify in g the. Buy in g. On the other hand, purchas in g more capability than will ever be. Signal averag in g can help the situation in this case. Furthermore, higher. Input accuracy is related to, but not equal to, in put resolution. The accuracy of. Input accuracy can be specified in a number of ways. Three of the more common. All calculations. A generally accepted way.

The types of error that come in to play in clude non-l in earities,. Non-l in earities have a major impact on ENOB. They are deviations of analog. There are two types of non-l in earity: in tegral and differential. Differential nonl in earity. Integral non-l in earity refers to deviations in the shape of the conversion over. It measures the deviation of each.

Both forms of non-l in earity are typically measured with a ramp. For multi-channel boards that switch from channel to channel us in g a multiplexer,. In fact, any distortion or error occurr in g anywhere. For a s in e wave in put signal, it. Actual SNR can be measured us in g a function generator that provides a s in e. This is taken as.

Therefore, in terms of the FFT analysis, it is the ratio of the rms sum. Nyquist frequency, exclud in g DC. ENOB is then calculated from the measured. Typically, the maximum sample rate is. The maximum sample rate. A s in gle channel. If different ga in s are set for channels in a scan list, the overall. A ga in queue permits specify in g a different ga in for each channel. As the. Each conversion method offers a different comb in ation of performance and.

It is important to be aware of the limitations associated with. Table briefly describes some of the ma in. The capacitor is charged first by the unknown signal for a set time in terval. The in tegration time. Very high speed analog in put boards use flash converters to achieve acquisition. Collectively, the comparator outputs. For this reason, very high speed analog in put boards.

Further, because. Sigma-delta conversion uses an oversampl in g modulator a voltage-to-frequency. An alias is a false signal component that appears in sampled data acquired at. Alias in g errors occur when a signal conta in s frequency. Alias in g errors are hard to detect and almost impossible to remove us in g software.

The solution to alias in g is to use a high enough sampl in g rate or, if this. Among the more common types of anti-alias in g filters. The stop band. The filter type determ in es. The ability to perform four-wire measurement techniques in conjunction with. Several different digital. Table Most feature protection aga in st occasional transients, but are not in tended. Switch contacts can be in terfaced to a digital in put by add in g a pull-up resistor,.

A common software technique in volves perform in g. This may impose a slight. Hardware debounc in g is relatively in stantaneous. Hardware debounc in g requires a flip-flop circuit for each digital in put channel.

Switches designed for dry circuits have softer crosspo in t contacts that. This is one case in which specify in g. A TTL ord in ary digital in put is designed to read signal levels that satisfy the. A slow mov in g. Slow mov in g digital signal can result in unreliable. The result. Somewhat the same effect can be achieved in software by ignor in g state changes.

If higher current is needed, substitute a. These modules. Solid-state relay modules also offer an advantage in controll in g in ductive AC. Similarly, isolated control in volves. This isolation in cludes the signal and ground connections.

Figures and show methods suitable for isolat in g digital in puts. In the case of the isolated digital in put in Figure , the diode side of the optoisolator. For the isolated output shown. Therefore, it is more common to f in d.

Improper ground in g is a common source of problems affect in g analog measurements. When a piece of equipment is plugged in to a three-wire grounded AC outlet,. However, there can be a considerable. When in struments,. The result in g voltage. Ground loops can occur in any type of measurement setup, but are most troublesome. Be sure, however, that all digital grounds except for. Several sensor technologies are available for this purpose, in clud in g thermocouples,.

However, there are many different types of thermocouples,. These practices result in relatively slow measurement. Furthermore, thermocouple output is nonl in ear, so l in earization. F in ally, thermocouple measurements require the use of a reference junction. Rather than resort in g to a separate thermocouple junction and reference temperature. Although these features result in higher complexity and higher hardware costs,. Alloy 1 and Alloy 2. The result can be expressed by the follow in g equation:.

If the temperatures of J2 and J3 are equal a condition. Elim in ation of the ice bath and correspond in g reference junction for each. As a first step in this process, we can assume that the thermocouple measurement. This is, in fact, the. Next, we can concentrate on what happens between the in put term in als and. The chief reason for immers in g the reference junction in an. Ideally, these term in als J2 and J3 will be at the same.

This ensures that the in strument. Thus, we have succeeded in elim in at in g. The f in al step in simplify in g this thermocouple in put circuit is to elim in ate the. Typical in put for a J-type thermocouple, us in g a semiconductor. Development of a typical thermocouple in strument in put.

With in the usable temperature range of any thermocouple, there is a proportional. In fact, most thermocouples are. In order to obta in temperature. At the opposite end of the. In general, neither of these methods is. In addition to l in eariz in g thermocouples in the analog doma in , it is possible. This is accomplished by. The follow in g describes the.

First, the follow in g equation determ in es the measured output of the thermocouple:. It would then add this voltage to the. That seems really stupid. How many years did the US officials put up with the microwave bombardment of our embassy in Moscow?

Were they victims of their own propaganda, that MW radiation is harmless? Dig the frequencies they used: 2. The Russians -knew- those frequencies would do some damage. I expect they know more about sounds effects on the body than we do.

What better way to make Cuba an enemy? One of very few possibilities. Of course, all this depends on the sound being the -cause- of these problems. This may not be the case. I met a guy in jail who had been hit in the head with a baseball bat.

I forgot to mention then that the loud sound in my dream was caused by the expanding rock vapor. Now we are in troubled waters here, I wanted to avoid that. TFC has rightly a dedicated tamper evident HW for the serial transmission, so what is the talking about pin reassignment?

The socket pin is the pin, one is the input, the other the output. It does not accept code from that pin, not at boot or later, only data. Data is HW shifted into a shift register and buffer, depending on speed setting, agnostic to bits and bytes, it is your SW that makes use of it. Think of the tamper evident black box, it is yours, until you rely on dubious libraries ….

Forget about the NH, it is compromised by default. But the RxM is the same as the TxM and it is not until someone popped it open. No malware on RxM. Only your SW — Um, are you hinting at some irregularities? Yes, I think you should have a deeper look into serial HW. For example, the older RasPi had only one serial port, a real one with HW. Many have complained about. Simpler chips sometimes have advantages.

No go! The coupler is a mechanical security, btw. I was poking around trying to write directly to a graphics display. The silence from the habitually screaming chain printer was especially eerie. After a few moments the expletives began to fuse from all the other users. I inconspicuously packed my stuff and silently left.

Never tried it again. More and more sites seem to be putting these insanely slow ad banners up … No more victimizing the browser! At some point the roads will have too many pot holes and the garbage piles too deep. People will move on to something else. Books, as in physical books, are making a comeback.

Do you mean Clive Robinson? I am sure I am not the only reader entirely bored senseless by the US politics carry on by people who otherwise have quality things to contribute and if I am being optimistic I would imagine they should know better. There is a browswer ad-on called noizy.

Bruce you have touched upon this topic in your books. Care to comment? Anyone else care to offer a more technical assessment of it utility or lack there? That is energy has been applied over a period of time. Thus bio-engineering could in theory make highly toxic poisons that are triggered by a persons DNA etc. Thus finding the root cause of these injuries may not happen untill after one or more of those effected die.

One such is Dimethylmercury CH3 2Hg, which inhibits essential oxidative and photosynthetic pathways. The exemplar I had in mind has not been unique among the commenters here, and I know counterparts personally. To the extent that it leads them to transparently wrong interpretations, I think it of considerable importance. Please note that I did not introduce the political theme to this thread, but rather responded to a conversation on that theme that had gone quite a few rounds already.

Finally, this is the squid post … Bruce as usual posted whimsical stuff about squid as an opening to a thread for … general discussion. Detailed disclosure of a covert attack by one UN member state against another, and the interpretation of the significance of that disclosure, is actually a big deal on the topic of SECURITY. I also saw that the Internet Czar of China has been dismissed for dreadful antisocial behaviors. I hear you on the funding problem. We need a finance guy to get this up and running.

Maybe some Crowdfunding or a grant from a large non-profit entity. But, things can get tricky when money men are involved. It crashed every hour using a 14 inch LCD display. The same with Beaglebone later. I think the Dell laptops would be the best. They are more durable. I can remove radio and other parts on older dells [dual core] with some difficulty but it can be done.

I need to digest more information on this project. This sounds good. Good work maqp. This looks likes a viable project. Again, I have to digest more information before I start ordering parts and buying laptops. Thanks for your reply. I am not quite sure what you are driving at. Are you saying the Network Handler Device be it multifunctional router, Server Router, or other device is always going to be compromised?

As the IM client running on NH only relays public keys and signed ciphertexts, the harsh and often deserved critique received by libpurple is not a security issue the same way confidentiality of PGP ciphertexts do not depend on whether attacker controls email servers; NH is not part of the TCB, it is part of the ciphertext routing network. There is however a lot more to security than just encryption. I get the idea that the Network Handler or Internet relay machine is considered compromised but it only handles encrypted packets so the danger is low.

The danger is not zero but low. Clive — Thanks for your helpful comments. I am a fan of Asimov and I was pleased to see here some months ago the discussion of empire from his trilogy. I think that he was on the record that he regretted adding the fourth book to the series.

Ditto for the microwaves from cell phones. It appears that the trauma in Cuba was a very concentrated input. We could point to other systems where a small concentrated energy input is destructive. Diamonds fail from impact, because very little energy is required to break all of the chemical bonds in a single cleavage plane, and yet diamonds rank among the strongest materials on your planet.

Their melting or sublimation point also ranks very high, although they would erode rapidly in air or oxygen at elevated temperatures. When I was a cold war kid, I thought that the Russians were bent to evil. And I was suspicious of Germans for having embraced Hitler and committed various genocides.

As I began to understand more of the history, I realized the role that the US played in causing those events, as the same time coming to a much more sympathetic view that they are just humans who live with the same conflicts of interest as everyone else on the old blue marble of entropy maximization. One of the conflicts of interest is our need to put psychopaths in the bus drivers seat, to be sure that mayhem can be visited on the neighboring tribe. Never stopping to consider that the mayhem can be directed anywhere.

I had some inkling how bitter the siege at Stalingrad had been. Around the same time, there was a George Clooney movie that cast the Russians in a sympathetic light. We all know who lit those fires. This one is the through-hole version you can insert into sockets.

The other one is for circuits that use surface mount technology. Difference here. It would also be quite problematic for users to bridge the correct serial adapter from host OS to the correct guest OS. I wanted it to be something everyone can try without any hardware investments. But the local testing launcher on Ubuntu has options to launch it with simulators that graphically show when data transits between the simulated computers: Screenshot When data transits from one simulated computer to another, the data diode simulators blinks.

But getting back to KFC today, it appears the colonel does not command his forces and now has a rising bio-hazard issue as a result…. I rarely eat fast food as the price differential in this country between raw ingredients in the supermarkets and the fast food joints is around thus if I want fried chicken I generally make it myself. Eventually company directors will wake up and stop listening to the big four accountancy firms that look the other way rather than do what the law requires of them.

Because accountancy is not profitable whilst financial engineering and consultancy schemes are. I see your point. Note I said ultimately. No one can forget that Russian lifespans dropped to the fifties while CIA agents looted the country. Absent the malign influence of CIA looting, Russia would have been much quicker to reconstruct itself with rights and rule of law. But splitting, reconstituting, and demilitarizing were salutary measures consistent with Perestroika.

As in the Soviet Union, the trick is being in the right part when it happens. You want to be living in the Saint Petersberg of America, not in its Ashgabats. The dedicated energy-gapped computer would either need to run the decryption itself, or it needs an access to some decryption oracle like a smart card that holds the key. Could you draw me a schematic about devices, their purposes and how unidirectionality works in this case. When there is separate error checking and correction, the assumption must be adversary has attempted attack.

Decryption system must by definition have the key, and when it decrypts, it will by definition learn the plaintext. What do you mean? No they did not. There will always exist redundancy in plaintext data. What happens with Truecrypt is, after the key has been derived from password and salt, it will attempt to decrypt and if the resulting plaintext contains ASCII string TRUE in it in known offset, it will conclude decryption was successful.

That completely ignores known plaintext attacks. XChaCha20 is useless without authentication. Sadly usually teachers leave out that OTP is meant to be used with unconditionally secure authentication. Optimization attains optimal environment in Greenhouse control is a typical time delay soil roots neighbourhood and air system, see fig. All actions environment for the plant, with optimal affect their primarily controlled state after agricultural results and comparison of some time, and more specifically the plant cultivation methods and control approaches quality is resumed after some months.

For example, table space is occupied, chips must be stacked after each transaction and chip stacks are sometimes upset and must be re-stacked. The present invention eliminates the foregoing difficulties and, in addition, adds excitement and a new strategic dimension to the game of poker. For example, the invention displays for all players the pot at stake in a particular game.

The wagered amount the raise, and the amount necessary for a player to stay in may be displayed to an individual player upon demand. It also displays which players are in the game, whether a bet exceeds a player's wealth, whose turn it is to be, and the winner at the completion of a hand.

The order of betting is strictly enforced, except during the ante phase when random betting and entry is permitted. In addition, individual players have private access to data indicative of their personal total wealth and their personal stake in each individual on-going game. The game is accellerated for additional excitement because play is not seriously interrupted for the banking tasks and annoying pot and game status inquiries of inattentive players.

There has provided a multiple player game data processing system with wager accounting for determining respective aggregate points or wealth, gains and losses and the stake of each of a plurality of players wagering against each other in a game of chance. The system includes means for determining an aggregate amount, or pot, wagered by the players, means for determining the amount necessary for a player to enter and remain in the game as initial and successive wagers are made, and means for increasing and decreasing each player's respective aggregate wealth or accumulated points in accordance with the wagers made and the outcome of the game.

The system includes a player game entry device or station for each player including respective wealth acknowledgement means for acknowledging and receiving wealth upon demand, wager selector means for registering and indicating an amount wagered and withdrawal selector means for registering withdrawal from the game.

Player wealth inquiry means for each respective player station is operative only at such station for selectively indicating a wealth amount for the respective player. A central processing unit is operatively coupled to the player stations for receiving the respective wagers and computing and indicating the pot at stake; for reducing such player's registered wealth in accordance with that player's respective wager; and for comparing the amount of each player's registered wager with a successive higher wager, for calculating the difference therebetween and for registering and indicating an amount necessary for such player to wager in order to remain in the game.

Means at the central station is operative to register and indicate a win and the amount thereof in response to the operation of the withdrawal selector means by all of the players but the winner of said game. The wealth selector means communicates with the central station and the winner's player station for increasing the wealth amount of the winner by the pot amount registered by the central station in response to wealth acknowledgement by the winning player.

Means is provided for designating one player station with bank function, and for changing said designation in response to a signal from such station designating another as the bank and an acknowledgement from said station. In FIG. The preferred device 10 is, as hereinbefore described, an electrical system for keeping track of the various aspects of an on-going poker game among a plurality of players. The game comprises a master or central station 12 and a plurality of, preferably eight 8 , player stations 14 interconnected to the master station 12 over dedicated channels 16 Although eight player stations 14 are shown, in a preferred embodiment, fewer may be used in a game.

Suffixes refer to particular player stations and are not used when referring to devices generally. The master station 12 has a plurality of sets of indicators 18 , one for each player station Each display 18 is dedicated to give information relevant to a player sitting opposite the same.

In addition, a plurality of digital displays 20 are provided for giving numerical information. The indicators 18 and displays 20 are conveniently located so that each player can see the information conveyed by the master station Although 4 digital displays 20 are shown, more or less may be used if desired because, unlike the indicators 18 , the digital displays 20 show information common to the game rather than individual players.

Each player station 14 has an alpha numeric keyboard 24 having individual keys 33 for inputting information and functional tasks to the system. The keys 33 are labeled or coded as follows:. The function of the keys 33 and corresponding operation of the device 10 shall be hereinafter described in detail in conjunction with a description of the various functional elements of the device. Referring to FIG. There is also shown in detail one of the eight player stations 14 1 connected in parallel to the central station 12 over the corresponding channel 16 1.

Each player station 14 has a player station interface 28P which couples the keyboard 24 of the player station 14 with the CPU 26 via the general interface 28G and the respective dedicated channel Each player station 14 is coupled in parallel to the data bus 30D of the central station general interface 28G via a dedicated channel A station address line SA, hereinafter described, addresses each player station 14 by a dedicated code unique to such station. The CPU thus communicates with each player station 14 individually and exclusively.

For a description of the player station 14, reference is directed to FIGS. Each player station 14 comprises a keyboard 24 with decoder 21 and display 22 and a player station interface 28P. One such keyboard 24, with decoder 21 and display 22 is incorporated into a hand-held calculator not shown such as Model No. TI manufactured by Texas Instruments. The device accepts inputs by mechanically shorting a matrix of respective horizontal and vertical wires 32 and The wires 32 and 34 selectively intersect at normally open contacts Each of said horizontal wires 32 receives phase shifted pulse inputs 32ae from a ring counter not shown for sequentially activating the wires in a known manner.

If, for example, key 33C is actuated, contacts 38C are closed and outputs c and e produce pulsed outputs as high signals 32c and 32e while the ring counter is disabled and all other outputs are low. A coded output unique to the closure of said switch 38c is thus produced. In a preferred embodiment, cable 40 also couples bus 30 to the player station interface 28P, which couples outputs of the keyboard 24 to the master station 12 over the channel 16 and vice versa. It should be understood that a cordless arrangement between player stations 14 and Central Station 12 is possible.

The player station interface 28P is hereinafter described. The buffer 42 steps down signals from the keyboard 24 to an appropriate voltage for the next stage. The buffer 42 is coupled as shown over output lines a-i to an erasable programmable read-only memory EPROM 44 which acts as a decoder.

The EPROM 44 decodes the signals over the lines a-i therefrom, and produces a coded output over its output lines a-h to a peripheral interface adaptor PIA 48, such as large scale integrated circuit interface manufactured by Motorola. PIA's are known as devices which provide parallel interfacing between some external device according to instructions from a central processing unit.

Because the buffer 42 merely steps down the signals from the keyboard, the inputs and outputs are logically the same. In a preferred embodiment, upon the occurrence of a key stroke, a selected output g of the buffer 42 goes low and provides a tag bit for setting a one-shot multi-vibrator or pulse stretcher 46, which is coupled to a trigger input i of the PIA The pulse stretcher 46 produces a gating pulse to PIA 48 which responds by producing an interrupt signal.

The CPU 26 recognizes a low going edge of an interrupt. Thus, if g goes low, another signal from the particular player station cannot generate an interrupt until the pulse shutter times out. Data output from the CPU may be gated to the player station 14 by means of other circuits in the player station interface 28P hereinafter described.

Such data includes wealth information, the player's personal account or stake in the game, the bet required to stay in the game, etc. It should also be understood that when CPU outputs data, an input interrupt will occur. During such time, the CPU recognizes and processes the input data from the station receiving output, but discards the data so obtained from that station upon completion of the output sequence.

The falling edge of the signal generated by the pulse stretcher 46 generates the interrupt. However, during output the interrupt is masked. The system does not recognize the interrupt generated by the station while receiving the output. The PIA 48 has outputs a-f which are coupled to a buffer 50 having step-up gates 50af, such as integrated circuits manufactured by National Semiconductor. The buffer 50 has outputs a-f coupled to a decoder 52 FIG. The decoder 52 includes three decoders 52ac such as CD integrated circuits manufactured by RCA and sometimes referred to as "one of eight" decoders.

The decoders 52ac receive selected outputs a-f of the buffer For example, each decoder 52ac receives outputs a-c of the buffer 50 at its corresponding input a-c. Further, each decoder 52ac respectively receives one each of the remaining outputs d-f of the buffer 50 at a respective corresponding input d', e' and f'. Therefore, the outputs a-c of buffer 50 provide coded data, and the outputs d-f, when energized, select one of the decoders 52ac to receive such data. For example, when output f of the buffer 50 is high or on, outputs d and e are low.

Thus, only decoder 52c receives an input f' enabling it to receive the data from the outputs a-c. Likewise, when output e of the buffer 50 is high, the d and f outputs are low, and only decoder 52b receives an input e' to render it active. The decoder 52 is coupled to a switching device 54, which preferably includes analog switches 54ae such as CD analog switch devices 54ae manufactured by RCA.

Each switch 54ae closes or short circuits selected outputs a-h thereof in response to coded inputs from the decoder In the drawing, it can be seen that the decoder 52a has outputs a-d coupled to corresponding inputs a-d of the analog switch 54a. The remaining outputs e-h of decoder 52a are coupled to inputs a-d of analog switch 54b.

Likewise, decoder 52b has half of its inputs a-d coupled to the analog switch 54d. Finally, decoder 52c has four outputs coupled to the analog switch 54e. Other outputs of the decoder 52c not shown are spares and not used in this particular circuit.

It should be understood that while an output to display 22 is occuring, the system software does not permit or recognize an input from the particular player station. Thus, a conflict of signals is avoided. Outputs from the decoders 52 actuate inputs to the various analog switch devices 54ae for selectively closing or short circuiting selected outputs thereof. For example, the decoder 52a, when energized by actuation of its d' input as hereinbefore described, transmits the coded data from the inputs a-c for driving selected ones of its outputs a-h to an "on" condition.

If the output c of the decoder 52a is driven high, outputs e-f of the analog switch 54a become short circuited by internal circuitry thereof. This is analogous to the closure of a switch 33C at intersection 38C'. When corresponding horizontal and vertical wires 32 and 34 of keyboard 24 are closed at 38C' by switch 54a, it is as if switch 33C had been manually closed. The player station 14 therefore responds by providing a digital output to decoder 21 driving display 22, as hereinbefore described.

In 54ae have corresponding outputs which are coupled in parallel with the respective normally open contacts 38 of the matrix hereinbefore described. The player station interface 28P thus provides input data to the central station 12 from the keyboard 24, which input data is simultaneously decoded at 21 and displayed on the player statio display 22 by virtue of the closure of the selected normally open contacts Likewise, the player station interface 28P couples data transmitted from the central station 12 to the corresponding player station 14 by closing selected switches in parallel with the normally open contacts 38 of the keyboard 24 for decoding at 21 and display on the player station display The PIA 48, hereinbefore described, performs other functions as well as the routing of input and output data between the player station 14 and the central station The operation and programming of the is explained in detail in the manual.

In a preferred embodiment, port A is programmed as an output port. Port B is an input port that has been conditioned to accept an interrupt as hereinbefore defined. This occurs when a station address SA lead is actuated at control port C. In connection with the foregoing, the present invention utilizes a memory mapped system. The codes condition the PIAs 48 such that selected terminals act as inputs or outputs etc.

This system software handles input output functions of the PIAs 48 In other words, the PIAs 48 are programmed on initialization to act in the manner desired for example addressing input and output register selects SI and SO , such that, it is only necessary to call on a particular PIA and its output port A or input port B acts accordingly.

Other systems are possible for selecting input and output function, and the like. However, the memory mapped software of the present invention has been found to be a preferred and efficient system for accomplishing the task. Input data produced as a result of closure of certain ones of the normally open contacts 38 resulting from mechanical key strokes is transmitted to the CPU 26 by PIA via buffer 42 and EPROM 44 as hereinbefore described.

PIA 48 has a clock input C , which is produced by a clock hereinafter described at the central station The clock produces pulses which hold the PIA 48 in synchronism with all the other player stations 14 and the central station The interrupt IR communicates a pulse to the central station 12 indicating that data is available from the keyboard 24 for interpretation by the central station The PIA 48 may be reset to an initial condition by means of the reset input R as shown.

When the system is initially turned on, a reset pulse is coupled to the PIAs 48 for enabling the circuits and registers of the PIAs to receive the coded signals from the CPU 26 whereby the portsof PIAs 48 are mapped or conditioned to act as inputs and outputs. For a description of the master or central station 12 reference is directed to FIGS.

The master station 12 includes the CPU 26 and general interface 28G. Each player station interface 28P is coupled in parallel with general interface 28G over its respective channel 16 including data bus 30D Each player station 14 is operative for communicating with the master station 12 to the exclusion of all the other player stations 14 by means of an interrupt function of the CPU, which processes one interrupt at a time.

CPU 26 recognizes the station by selective actuation of the respective Station Address SA for the particular player station 14 and testing the polled station for the presence of a valid address code. In a preferred embodiment, the CPU 26 processes data and produces outputs to the player stations 14 , the master displays 20 and indicator lights 8 In the event of a key stroke produced at any play station, the CPU 26 completes the program instruction i. Thereafter the CPU 26 resumes the program function.

The data received from the player station is later processed in accordance with the system software. The general interface 28G includes inverting bidirectional driver 62 including two DM integrated circuits 62W, 62R manufactured by National Semiconductor.

The drive 62 is coupled into the CPU 26 data bus 30D. Communication between the CPU 26 and player stations 14 is accomplished by means of selectively addressing each of the player stations 14 separately over select address line SA Address bus 30A is coupled to the general interface 28G as shown.

The address bus 30A is coupled to the channels 16 carrying respective select address lines SA dedicated to respective player stations 14 The RAM 64 is capable of holding at least bytes of eight bit data in each RAM 64AC information and may be used to store values to be displayed, temporary results of arithmetic routines, system control, variable accounts, game statistics, etc. Thus, in accordance with instructions established in the computer program, the RAM 64 contains or stores non-conflicting input and output data for each player station 14 and the central station The clock line C operates the RAM 64 in synchronism with all other devices in the apparatus.

A valid address VA line carries a signal that verifies that the information on address bus 30A is in fact a valid address. In the preferred embodiment, the CPU 26 respectively reads and writes information to and from the various player stations 14 In addition, the CPU 26 provides visual indication in the central station 12 of the information common to all the players by means of the digital display 20 and the particular information relevant to a player station 14 associated with a set of indicator lights 18 as hereinbefore noted.

Other portions of the system, including the indicators 18, displays 20 and player stations 14, are not responsive to data on the data bus 30D unless they have been preconditioned to be responsive thereto. In other words, if the RAM 64 has been initialized to communicate with the CPU 26, other portions of the system are simultaneously initialized not to be responsive to the RAM The CPU 26 communicates with the player stations 14 and vice-versa.

The RAM 64 and the player stations 14 do not directly communicate with each other. The CPU 26 controls the indicators 18 and displays 20 in the central station 12 by means of a peripheral interface adaptor PIA Each PIA 66 receives coded data from CPU 26 over data bus 30D representing information commonly available to all players in the game, e. A selector 88, coupled to PIA 66, enables it to operate selected outputs for actuating indicators 18 and displays The PIA s 66A and 66B are selectively enabled to be responsive to the data on the data bus 30D for providing input to indicators The data is communicated from the PIA s 66A and 66B to a solid state switching device 68 which includes a plurality of solid state switches 68ah, such as Sprague UD power drive integrated circuits.

Coded information from the CPU 26 causes one or more of the outputs of the PIA s 66A and 66B to become low for causing the selected switches 68ah to drive one or more of the indicator lights 18 on. The PIA 66C is dedicated to be responsive to the data from the CPU for driving selected inputs of the digital display 20 to an on condition thereby creating an alpha numeric display of information relevant to the game. The PIA 66C has one set of outputs a-h coupled to booster 82, including a pair of booster circuits 82a and 82b, such as integrated circuits , manufactured by National Semiconductor.

These factors need to be considered when select in g components to. This application would best be served with an op amp with a very high in put. More recent trends in op amp design have been.

Were they victims of their own propaganda, that MW radiation is harmless? Dig the frequencies they used: 2. The Russians -knew- those frequencies would do some damage. I expect they know more about sounds effects on the body than we do. What better way to make Cuba an enemy?

One of very few possibilities. Of course, all this depends on the sound being the -cause- of these problems. This may not be the case. I met a guy in jail who had been hit in the head with a baseball bat. I forgot to mention then that the loud sound in my dream was caused by the expanding rock vapor.

Now we are in troubled waters here, I wanted to avoid that. TFC has rightly a dedicated tamper evident HW for the serial transmission, so what is the talking about pin reassignment? The socket pin is the pin, one is the input, the other the output. It does not accept code from that pin, not at boot or later, only data. Data is HW shifted into a shift register and buffer, depending on speed setting, agnostic to bits and bytes, it is your SW that makes use of it.

Think of the tamper evident black box, it is yours, until you rely on dubious libraries …. Forget about the NH, it is compromised by default. But the RxM is the same as the TxM and it is not until someone popped it open. No malware on RxM. Only your SW — Um, are you hinting at some irregularities? Yes, I think you should have a deeper look into serial HW.

For example, the older RasPi had only one serial port, a real one with HW. Many have complained about. Simpler chips sometimes have advantages. No go! The coupler is a mechanical security, btw. I was poking around trying to write directly to a graphics display. The silence from the habitually screaming chain printer was especially eerie. After a few moments the expletives began to fuse from all the other users.

I inconspicuously packed my stuff and silently left. Never tried it again. More and more sites seem to be putting these insanely slow ad banners up … No more victimizing the browser! At some point the roads will have too many pot holes and the garbage piles too deep.

People will move on to something else. Books, as in physical books, are making a comeback. Do you mean Clive Robinson? I am sure I am not the only reader entirely bored senseless by the US politics carry on by people who otherwise have quality things to contribute and if I am being optimistic I would imagine they should know better. There is a browswer ad-on called noizy. Bruce you have touched upon this topic in your books. Care to comment? Anyone else care to offer a more technical assessment of it utility or lack there?

That is energy has been applied over a period of time. Thus bio-engineering could in theory make highly toxic poisons that are triggered by a persons DNA etc. Thus finding the root cause of these injuries may not happen untill after one or more of those effected die. One such is Dimethylmercury CH3 2Hg, which inhibits essential oxidative and photosynthetic pathways. The exemplar I had in mind has not been unique among the commenters here, and I know counterparts personally. To the extent that it leads them to transparently wrong interpretations, I think it of considerable importance.

Please note that I did not introduce the political theme to this thread, but rather responded to a conversation on that theme that had gone quite a few rounds already. Finally, this is the squid post … Bruce as usual posted whimsical stuff about squid as an opening to a thread for … general discussion. Detailed disclosure of a covert attack by one UN member state against another, and the interpretation of the significance of that disclosure, is actually a big deal on the topic of SECURITY.

I also saw that the Internet Czar of China has been dismissed for dreadful antisocial behaviors. I hear you on the funding problem. We need a finance guy to get this up and running. Maybe some Crowdfunding or a grant from a large non-profit entity. But, things can get tricky when money men are involved. It crashed every hour using a 14 inch LCD display. The same with Beaglebone later. I think the Dell laptops would be the best.

They are more durable. I can remove radio and other parts on older dells [dual core] with some difficulty but it can be done. I need to digest more information on this project. This sounds good. Good work maqp. This looks likes a viable project. Again, I have to digest more information before I start ordering parts and buying laptops. Thanks for your reply.

I am not quite sure what you are driving at. Are you saying the Network Handler Device be it multifunctional router, Server Router, or other device is always going to be compromised? As the IM client running on NH only relays public keys and signed ciphertexts, the harsh and often deserved critique received by libpurple is not a security issue the same way confidentiality of PGP ciphertexts do not depend on whether attacker controls email servers; NH is not part of the TCB, it is part of the ciphertext routing network.

There is however a lot more to security than just encryption. I get the idea that the Network Handler or Internet relay machine is considered compromised but it only handles encrypted packets so the danger is low. The danger is not zero but low. Clive — Thanks for your helpful comments. I am a fan of Asimov and I was pleased to see here some months ago the discussion of empire from his trilogy.

I think that he was on the record that he regretted adding the fourth book to the series. Ditto for the microwaves from cell phones. It appears that the trauma in Cuba was a very concentrated input. We could point to other systems where a small concentrated energy input is destructive.

Diamonds fail from impact, because very little energy is required to break all of the chemical bonds in a single cleavage plane, and yet diamonds rank among the strongest materials on your planet. Their melting or sublimation point also ranks very high, although they would erode rapidly in air or oxygen at elevated temperatures. When I was a cold war kid, I thought that the Russians were bent to evil. And I was suspicious of Germans for having embraced Hitler and committed various genocides.

As I began to understand more of the history, I realized the role that the US played in causing those events, as the same time coming to a much more sympathetic view that they are just humans who live with the same conflicts of interest as everyone else on the old blue marble of entropy maximization. One of the conflicts of interest is our need to put psychopaths in the bus drivers seat, to be sure that mayhem can be visited on the neighboring tribe.

Never stopping to consider that the mayhem can be directed anywhere. I had some inkling how bitter the siege at Stalingrad had been. Around the same time, there was a George Clooney movie that cast the Russians in a sympathetic light. We all know who lit those fires. This one is the through-hole version you can insert into sockets. The other one is for circuits that use surface mount technology.

Difference here. It would also be quite problematic for users to bridge the correct serial adapter from host OS to the correct guest OS. I wanted it to be something everyone can try without any hardware investments. But the local testing launcher on Ubuntu has options to launch it with simulators that graphically show when data transits between the simulated computers: Screenshot When data transits from one simulated computer to another, the data diode simulators blinks.

But getting back to KFC today, it appears the colonel does not command his forces and now has a rising bio-hazard issue as a result…. I rarely eat fast food as the price differential in this country between raw ingredients in the supermarkets and the fast food joints is around thus if I want fried chicken I generally make it myself. Eventually company directors will wake up and stop listening to the big four accountancy firms that look the other way rather than do what the law requires of them.

Because accountancy is not profitable whilst financial engineering and consultancy schemes are. I see your point. Note I said ultimately. No one can forget that Russian lifespans dropped to the fifties while CIA agents looted the country. Absent the malign influence of CIA looting, Russia would have been much quicker to reconstruct itself with rights and rule of law.

But splitting, reconstituting, and demilitarizing were salutary measures consistent with Perestroika. As in the Soviet Union, the trick is being in the right part when it happens. You want to be living in the Saint Petersberg of America, not in its Ashgabats. The dedicated energy-gapped computer would either need to run the decryption itself, or it needs an access to some decryption oracle like a smart card that holds the key. Could you draw me a schematic about devices, their purposes and how unidirectionality works in this case.

When there is separate error checking and correction, the assumption must be adversary has attempted attack. Decryption system must by definition have the key, and when it decrypts, it will by definition learn the plaintext. What do you mean? No they did not.

There will always exist redundancy in plaintext data. What happens with Truecrypt is, after the key has been derived from password and salt, it will attempt to decrypt and if the resulting plaintext contains ASCII string TRUE in it in known offset, it will conclude decryption was successful. That completely ignores known plaintext attacks. Mens knitted vest pattern free Cd non investing buffer definition However, many microprocessor applications do not require an exact.

MC68HC11 microcontroller control of a greenhouse environment as a time delay system.

A short summary of this paper. Download Download PDF. Translate PDF. The nature of the greenhouse problems in conjunction with the microcontroller capabilities is given as a time delay control system and states decoupling problems are discussed. The greenhouse model - controller system operation is simulated and the results are discussed. Different plants greenhouse environmental demands are taken into account by changing controller set points, control architectures and data base integration.

Greenhouse control is considered a batch control system during start-up and run as continuous time discrete control algorithm later in the background. Greenhouse control is a typical time delay system. Relative soil Modern intensive cultivation use artificial coverage of the plant and its dry weight is means, including light to assist and optimize strongly related Chandra, et al, By temperature The paper designs and implements a controlling and suitable quantities of liquified microcontroller-based control system suitable fertilizer and nutritions supply for a pre- for greenhouse monitoring and control.

It selected intensive cultivation, vegetables, consists of the microcontroller, the interface, fruits, flowers and exotic plants difficult to be the sensors, the actuators and their drivers. Thermal environments and sometimes they are of losses are directly proportional to the specialized use. The basic reasons to invest in greenhouse size. Sensors accuracy considerations in not appear in the published results. The greenhouse data aquisition is not as much greenhouse controller should be tested at critical as in other industrial applications, but extreme conditions for robustness.

All actions environment for the plant, with optimal affect their primarily controlled state after agricultural results and comparison of some time, and more specifically the plant cultivation methods and control approaches quality is resumed after some months. For example, table space is occupied, chips must be stacked after each transaction and chip stacks are sometimes upset and must be re-stacked.

The present invention eliminates the foregoing difficulties and, in addition, adds excitement and a new strategic dimension to the game of poker. For example, the invention displays for all players the pot at stake in a particular game. The wagered amount the raise, and the amount necessary for a player to stay in may be displayed to an individual player upon demand.

It also displays which players are in the game, whether a bet exceeds a player's wealth, whose turn it is to be, and the winner at the completion of a hand. The order of betting is strictly enforced, except during the ante phase when random betting and entry is permitted.

In addition, individual players have private access to data indicative of their personal total wealth and their personal stake in each individual on-going game. The game is accellerated for additional excitement because play is not seriously interrupted for the banking tasks and annoying pot and game status inquiries of inattentive players. There has provided a multiple player game data processing system with wager accounting for determining respective aggregate points or wealth, gains and losses and the stake of each of a plurality of players wagering against each other in a game of chance.

The system includes means for determining an aggregate amount, or pot, wagered by the players, means for determining the amount necessary for a player to enter and remain in the game as initial and successive wagers are made, and means for increasing and decreasing each player's respective aggregate wealth or accumulated points in accordance with the wagers made and the outcome of the game.

The system includes a player game entry device or station for each player including respective wealth acknowledgement means for acknowledging and receiving wealth upon demand, wager selector means for registering and indicating an amount wagered and withdrawal selector means for registering withdrawal from the game.

Player wealth inquiry means for each respective player station is operative only at such station for selectively indicating a wealth amount for the respective player. A central processing unit is operatively coupled to the player stations for receiving the respective wagers and computing and indicating the pot at stake; for reducing such player's registered wealth in accordance with that player's respective wager; and for comparing the amount of each player's registered wager with a successive higher wager, for calculating the difference therebetween and for registering and indicating an amount necessary for such player to wager in order to remain in the game.

Means at the central station is operative to register and indicate a win and the amount thereof in response to the operation of the withdrawal selector means by all of the players but the winner of said game. The wealth selector means communicates with the central station and the winner's player station for increasing the wealth amount of the winner by the pot amount registered by the central station in response to wealth acknowledgement by the winning player.

Means is provided for designating one player station with bank function, and for changing said designation in response to a signal from such station designating another as the bank and an acknowledgement from said station. In FIG. The preferred device 10 is, as hereinbefore described, an electrical system for keeping track of the various aspects of an on-going poker game among a plurality of players.

The game comprises a master or central station 12 and a plurality of, preferably eight 8 , player stations 14 interconnected to the master station 12 over dedicated channels 16 Although eight player stations 14 are shown, in a preferred embodiment, fewer may be used in a game.

Suffixes refer to particular player stations and are not used when referring to devices generally. The master station 12 has a plurality of sets of indicators 18 , one for each player station Each display 18 is dedicated to give information relevant to a player sitting opposite the same.

In addition, a plurality of digital displays 20 are provided for giving numerical information. The indicators 18 and displays 20 are conveniently located so that each player can see the information conveyed by the master station Although 4 digital displays 20 are shown, more or less may be used if desired because, unlike the indicators 18 , the digital displays 20 show information common to the game rather than individual players.

Each player station 14 has an alpha numeric keyboard 24 having individual keys 33 for inputting information and functional tasks to the system. The keys 33 are labeled or coded as follows:. The function of the keys 33 and corresponding operation of the device 10 shall be hereinafter described in detail in conjunction with a description of the various functional elements of the device.

Referring to FIG. There is also shown in detail one of the eight player stations 14 1 connected in parallel to the central station 12 over the corresponding channel 16 1. Each player station 14 has a player station interface 28P which couples the keyboard 24 of the player station 14 with the CPU 26 via the general interface 28G and the respective dedicated channel Each player station 14 is coupled in parallel to the data bus 30D of the central station general interface 28G via a dedicated channel A station address line SA, hereinafter described, addresses each player station 14 by a dedicated code unique to such station.

The CPU thus communicates with each player station 14 individually and exclusively. For a description of the player station 14, reference is directed to FIGS. Each player station 14 comprises a keyboard 24 with decoder 21 and display 22 and a player station interface 28P.

One such keyboard 24, with decoder 21 and display 22 is incorporated into a hand-held calculator not shown such as Model No. TI manufactured by Texas Instruments. The device accepts inputs by mechanically shorting a matrix of respective horizontal and vertical wires 32 and The wires 32 and 34 selectively intersect at normally open contacts Each of said horizontal wires 32 receives phase shifted pulse inputs 32ae from a ring counter not shown for sequentially activating the wires in a known manner.

If, for example, key 33C is actuated, contacts 38C are closed and outputs c and e produce pulsed outputs as high signals 32c and 32e while the ring counter is disabled and all other outputs are low. A coded output unique to the closure of said switch 38c is thus produced. In a preferred embodiment, cable 40 also couples bus 30 to the player station interface 28P, which couples outputs of the keyboard 24 to the master station 12 over the channel 16 and vice versa.

It should be understood that a cordless arrangement between player stations 14 and Central Station 12 is possible. The player station interface 28P is hereinafter described. The buffer 42 steps down signals from the keyboard 24 to an appropriate voltage for the next stage. The buffer 42 is coupled as shown over output lines a-i to an erasable programmable read-only memory EPROM 44 which acts as a decoder. The EPROM 44 decodes the signals over the lines a-i therefrom, and produces a coded output over its output lines a-h to a peripheral interface adaptor PIA 48, such as large scale integrated circuit interface manufactured by Motorola.

PIA's are known as devices which provide parallel interfacing between some external device according to instructions from a central processing unit. Because the buffer 42 merely steps down the signals from the keyboard, the inputs and outputs are logically the same. In a preferred embodiment, upon the occurrence of a key stroke, a selected output g of the buffer 42 goes low and provides a tag bit for setting a one-shot multi-vibrator or pulse stretcher 46, which is coupled to a trigger input i of the PIA The pulse stretcher 46 produces a gating pulse to PIA 48 which responds by producing an interrupt signal.

The CPU 26 recognizes a low going edge of an interrupt. Thus, if g goes low, another signal from the particular player station cannot generate an interrupt until the pulse shutter times out. Data output from the CPU may be gated to the player station 14 by means of other circuits in the player station interface 28P hereinafter described. Such data includes wealth information, the player's personal account or stake in the game, the bet required to stay in the game, etc.

It should also be understood that when CPU outputs data, an input interrupt will occur. During such time, the CPU recognizes and processes the input data from the station receiving output, but discards the data so obtained from that station upon completion of the output sequence.

The falling edge of the signal generated by the pulse stretcher 46 generates the interrupt. However, during output the interrupt is masked. The system does not recognize the interrupt generated by the station while receiving the output. The PIA 48 has outputs a-f which are coupled to a buffer 50 having step-up gates 50af, such as integrated circuits manufactured by National Semiconductor.

The buffer 50 has outputs a-f coupled to a decoder 52 FIG. The decoder 52 includes three decoders 52ac such as CD integrated circuits manufactured by RCA and sometimes referred to as "one of eight" decoders. The decoders 52ac receive selected outputs a-f of the buffer For example, each decoder 52ac receives outputs a-c of the buffer 50 at its corresponding input a-c. Further, each decoder 52ac respectively receives one each of the remaining outputs d-f of the buffer 50 at a respective corresponding input d', e' and f'.

Therefore, the outputs a-c of buffer 50 provide coded data, and the outputs d-f, when energized, select one of the decoders 52ac to receive such data. For example, when output f of the buffer 50 is high or on, outputs d and e are low. Thus, only decoder 52c receives an input f' enabling it to receive the data from the outputs a-c. Likewise, when output e of the buffer 50 is high, the d and f outputs are low, and only decoder 52b receives an input e' to render it active. The decoder 52 is coupled to a switching device 54, which preferably includes analog switches 54ae such as CD analog switch devices 54ae manufactured by RCA.

Each switch 54ae closes or short circuits selected outputs a-h thereof in response to coded inputs from the decoder In the drawing, it can be seen that the decoder 52a has outputs a-d coupled to corresponding inputs a-d of the analog switch 54a. The remaining outputs e-h of decoder 52a are coupled to inputs a-d of analog switch 54b. Likewise, decoder 52b has half of its inputs a-d coupled to the analog switch 54d.

Finally, decoder 52c has four outputs coupled to the analog switch 54e. Other outputs of the decoder 52c not shown are spares and not used in this particular circuit. It should be understood that while an output to display 22 is occuring, the system software does not permit or recognize an input from the particular player station. Thus, a conflict of signals is avoided. Outputs from the decoders 52 actuate inputs to the various analog switch devices 54ae for selectively closing or short circuiting selected outputs thereof.

For example, the decoder 52a, when energized by actuation of its d' input as hereinbefore described, transmits the coded data from the inputs a-c for driving selected ones of its outputs a-h to an "on" condition. If the output c of the decoder 52a is driven high, outputs e-f of the analog switch 54a become short circuited by internal circuitry thereof.

This is analogous to the closure of a switch 33C at intersection 38C'. When corresponding horizontal and vertical wires 32 and 34 of keyboard 24 are closed at 38C' by switch 54a, it is as if switch 33C had been manually closed. The player station 14 therefore responds by providing a digital output to decoder 21 driving display 22, as hereinbefore described. In 54ae have corresponding outputs which are coupled in parallel with the respective normally open contacts 38 of the matrix hereinbefore described.

The player station interface 28P thus provides input data to the central station 12 from the keyboard 24, which input data is simultaneously decoded at 21 and displayed on the player statio display 22 by virtue of the closure of the selected normally open contacts Likewise, the player station interface 28P couples data transmitted from the central station 12 to the corresponding player station 14 by closing selected switches in parallel with the normally open contacts 38 of the keyboard 24 for decoding at 21 and display on the player station display The PIA 48, hereinbefore described, performs other functions as well as the routing of input and output data between the player station 14 and the central station The operation and programming of the is explained in detail in the manual.

In a preferred embodiment, port A is programmed as an output port. Port B is an input port that has been conditioned to accept an interrupt as hereinbefore defined. This occurs when a station address SA lead is actuated at control port C. In connection with the foregoing, the present invention utilizes a memory mapped system. The codes condition the PIAs 48 such that selected terminals act as inputs or outputs etc. This system software handles input output functions of the PIAs 48 In other words, the PIAs 48 are programmed on initialization to act in the manner desired for example addressing input and output register selects SI and SO , such that, it is only necessary to call on a particular PIA and its output port A or input port B acts accordingly.
