Easy to build Z80 single board computer

[Alexis] sent in a single board computer he’s been working on. The project goal of his build was making it easily reproducible. From looking at the schematics, it’s one of the simplest fully-functional computers we’ve seen. The build runs CP/M 2.2 off of two 3.5 inch floppies. This opens up a lot of options as to what software is already available. Although it operates over a serial terminal, [Alexis] pretty much duplicated an Osborne I, only at double the speed.
[Alexis] got a little e-fame from his earlier 8088 homebrew computer built from very early 8088′s rescued from an electronics junk shop. These 8088 computers made the blog rounds by playing Still Alive with a [video=youtube;gBiIr-bFiKM]http://www.youtube.com/watch?v=yLS35kyYlOU"]SID chip[/URL] from a Commodore 64 and a [URL="http://www.youtube.com/watch?v=gBiIr-bFiKM[/video] FM synth chip.
For now, I guess we’ll have to settle for a video of [Alexis]‘ Z80 computer running CP/M. Check out a video after the break of his computer running the greatest Infocom adventure, Hitchhiker’s Guide to the Galaxy.
