Starting to simulate the 8080 microprocessor: the 8224 clock .

And finally, dynamic RAM:

Static RAM:

I put one file at a time because it doesn't work when I put more than one!

Going on: one more 74xxx. I should stop now because I have now all the TTL IC I needs to simulate my 8-bit computer. IC74170.CircuitProject I started to build RAM and ROM. To load the ROM I was surprised by the fact that the data must be stored in binary files. But it was not very difficult to trans...

Thank you very much for these advices. I started to work on this 8-bit computer project and I have already published some CIs I have made, in Circuit Talk "My first circuit: 74155". Between them, there are the 74122 and 74123 on-shots. I also looked at ROM and RAM. I have found it is very ...

I tried to simulate the 74122 and 74123 one-shot CIs. I used the ideia of counting a number of periods of the clock. My project has an 8-bit counter which resets a D flip-flop when the count is equal to the preset value. This value is informed with two nibbles (2 x 4 bits) specific to each one-shot ...
