Early 3.5" Floppy Drives

[Barry Watzman]

RE: "I have heard of (but not seen) machines with 8" floppies that run
MS-DOS 1.x (not real sure what version)."

Well, the Heathkit / Zenith Z-100 ran MS-DOS (called Z-DOS -- it was not PC
compatible at the hardware level) and also supported 8" floppy drives (in
fact a very nice accessory external dual-drive 8" floppy was offered).
Also, again not PC compatible, but the CompuPro (Godbout) systems had 8"
drives and in some configurations ran MS-DOS.  Also, the Seattle Computer
Products systems.  And there were 8" controllers for early PCs.
