Re: My first circuit: 74155

Going on: I programmed the 74164 8-bit serial -in parallel-out shift register. LogicCircuit works really good!

My first circuit: 74155

I am very proud to have deigned my first 74xxx circuit. I hope I did not let any error! (I verified the truth table and it seemed to be OK).

Re: 8bit computer

So I see that it is not impossible! I have the list of the CIs used in this computer. I started to search for those already programmed by Logic Circuit and I have found a lot. But there are some I did not found. Here is the list: TTL 74LS122 Retriggerable monostable multivibrator 74LS123 Dual Retrig...

Re: Library to build 8 bits or 16 bits computers

Hello Hans!

I am interested in simulating an 8080 microprocessor. Did you make some progress in your Z80 simulation?

With my best regards,

8bit computer

I would like to know if it is reasonable to attempt to simulate an old 8bit computer with Logic Circuit. It would be based on a 8080 microprocessor with a 48kb RAM and a 24kb ROM.
