Awesome, thanks for the link! I didn't remember that aspect of the 4004 project.
This would be a pretty amazing project. I wonder if you could get existing Uxn/Varvara applications like the Left text editor or Orca to run fast enough to be usable. Presumably for Orca you'd want to hook up external sound hardware rather than trying to bitbang the sound on the 8008, and I guess the same is even more true of a framebuffer.
If you were bitbanging RAM access at 7kbps it might be hard to get it to run instructions fast enough to be usable, though.
