Re: JK Flip-Flop via 12 Gates
Hello LLAD, Though you addressed your message to Eugene, I'm so free to react. The phenomen, you've mentioned isn't that particulary. It is known as positive logic and negative logic. In positive logic, you look at the "ones" in the truth table, in negative logic you look at the "zero...

Re: Unexcepted decoder output
Hello Volvagia, I get your problem. This problem also occurs often in real life. Mostly these problems are due to propagation delay times. Another important cause is the changing of counter-outputs. The low to high transitions and the high to low transitions aren't equal. First I have to say, that y...

Re: Library to build 8 bits or 16 bits computers
Hello everyone, Though I promised to send you my keyboards, I give you an other topic. Counters. For my projects I needed a different kind of counters. So I decided to design thes ones. This topic contains among others: Binary, BCD and Step-Counters. The Binary- and BCD-counters speak for themselves...

Orientation of outputs on the buttons.
Hello Eugene, if I may call you that way. I have a request. Is it possible, to choose on which side of a button, one can place the output. At this moment, when you place a button, with the output to an other side, than the right side, the button-text is placed wrong In the worst case, when the outpu...

Re: Library to build 8 bits or 16 bits computers
Hi everyone, I've now also translated part 5. This contains three ALU-concepts. These ALU-'s don't have a, so called, Carry Look Ahead Circuit. I will describe such a circuit in special circuits As far as now, the library contains the following topics Part 1: demultiplexers Part 2: multiplexers Part...

Re: Library to build 8 bits or 16 bits computers
Hello, I've translated the parts 3 and 4. In here you can find several tri-state applications and several register applications. As far as now, the library contains the following topics You will find all the parts in the first message. Older parts may be changed a little bit. Part 1: demultiplexers ...

Library to build 8 bits or 16 bits computers
Hello Everyone, In this forum, I've seen many misconceptions, sorry to say so. At this moment I'm trying to simulate the famous Z80-processor. For this I needed many basic solutions, among others, demultiplexers (decoders), multiplexers and so on. So now I'm making a kind of library, which contains ...

Re: Request to the webmaster
Hi Eugene, of course I want other people to comment on this topic, because other people might have great ideas. Hereby I'm thinking of the topic, as the ROM-counter, sent by Alexander. Maybe not practical, but sure original. Last night I've got a idea. Everytime I've finished a new category, I repla...

Request to the webmaster
Hello, I would like to load-up my whole library, wich is divided in several parts (categories). I'm thinking of doin' this step by step, because I prefer to keep the files synpotic. Would it be a good idea, to place a message (in no reply mode) with only the text of the category and accompanied by t...

computer
When I got to know the program for the first time, I was immediately enthousiast. So, last year I started to design a simple computer. I would like to know, if this would work. Yes, yes, it worked. The MEC was born (yeah, there is a similarity with the MAC, at least the characters are almost the sam...
