Currently getting parts together for a build. There are four extra slots. I'm going to use them for a serial board and extra RAM. Is there any PCB for ROM or is that going to be a DIY?
Also are there any Operating Systems that will work with the 8008?
Got one 8263 on FleaBay still looking for the rest of the multiplexers.
Regarding ROM, Len from 8008chron.com created a ROM board for the Mark-8. You could try contacting him about the schematics/gerber if you're interested.
