This was a very interesting read. I have read a bit about the 4004 before so I knew it was strange. But the level of obscurity is mind-blowing. Now I just got the urge to see how well I would be able to make a CPU with the same transistor count. It's not that much fewer than a 6502. 8 bit would make it so much easier to program.

Thanks for documenting your work so well!

Make it out of transistors and i'll port my MIPS emulator to it :)

Have you considered porting to the vacuum tube 1 bit / 1 Hz MC14500 clone?

a thought!

All it needs is to run a 4004 emulator. :-)
