Of course, this begs the question of why IBM pushed PC-DOS over CP/M-86.
Better licensing terms with Microsoft? Or purely the difficulty in
porting from CP/M to PC-DOS versus the ease of porting from CP/M to
CP/M-86, which might keep Xerox or others out of the market?

I used CP/M-80 on an Epson QX-10, and did some Turbo Pascal programming
on it. I drooled over the DEC Rainbow, but never had much interest in
the IBM-PC.
