Ben Eater has built his own 8-bit computer, and documented the process.

I built a programmable 8-bit computer from scratch on breadboards using only simple logic gates. I documented the whole project in a series of YouTube videos and on this web site.

There's something special about these DIY old-school projects that brings very fond memories back.

For those that aren't sure.. that object underneath his right hand is a paperback manual.

Are you saying Eater has a lot of fun with *bread*boards? Are they wholegrain? ;)

I did something similar for a digital logic class I took back in college. It's lots of fun making your own processor - everyone involved in computers should do it at least once in their life. The most expensive part is the breadboards you need - the parts themselves, being simple 7400 logic chips and the like, are ridiculously cheap.

I made my processor microcoded, using a bunch of EPROMs for the microcode. Wrote my own microcode compiler to generate files to burn in the EPROMs. I also had one level of pipe-lining in the design. Got an A for project. ;)
