I've been working your project since 2021 (Perseus-8 I think)... the wirewrap 6502 CPU :) It's a great project! Congrats!

Thank you for liking and following my project #PERSEUS-8 homemade 6502 computer ! Now I am making a single precision BCD floating point input/output machine language program on this computer.

Hi Augusto, thanks for following CPU4.
The CPU4 was a "push" in the direction of a "programmable micro-code" CPU. I felt it was chip expensive without any real advantage (too many clock cycles to do anything).
That is, it is a dead end.
My 8 bit TTA Interpreter project was a better implementation of the "programmable micro-code model", but an 8 bit memory paging system resulted in a unreasonably small memory page. Even so I did manage to code a serial I/O interrupt, call/return, push/pop codes, etc. I think a 12 bit version of the TTA Interpreter may have merit platform for a demonstration computer.
I do have a single/double cycle 4 bit CPU prototype in the pipeline that I am excited about. Just some pencil drawings at the moment. 16 instructions and less than 20 SSI chips excluding RAM/ROM.
As you have noticed I am not really a fan of LSI PROM microcode systems.

Thank you for liking and following my #PERSEUS-9 homemade mobile 6502 computer! I have been gradually updating my own floating point interpreter. This year I created a PROM programmer, which makes updating easier.
