I think I have a Zenith Z100 or something like that, it's the prebuilt version of the Heathkit. It's a pretty nice computer. It's got an 8088 and an 8085 so it can run both CP/M and DOS. Dual floppy drives too, and a S-100 bus so you can put expansion cards in.

I have a few manuals for it, but this guy only seems interested in older models.
