A slew of CP/M, Osborne, Kaypro and Heath retro computing software and hardware. Any tips or additional info is appreciated! The Heathkit / Zenith stuff is especially curious. I'm not sure what all it's actually for, system-wise. Possibly a H89/90. Turns out the Kaypro is a 4/83 + 88 making it compatible with MS-DOS. I also got the floppy drive working. There will be a proper and full-length review of these machines at some point.
