Come to think of it, my CP/M experience was without hard disks - it was an
Apple II with a Z80 card to run CP/M, and two 143kB floppies. The Z80 card
was manufactured by some outfit called Microsoft! It was their first piece
of hardware, I believe.

I needed CP/M to run DBaseII. Output was to a Qume daisywheel printer -
remember them?

Chris,
I also started with a CP/M machine, made by Xerox, but it had no hard drive.
It had two 8-inch floppy disk drives.
