I think you must have CP/M and CP/M-86 conflated with something
else. CP/M-80 was anything *but* "vapourware." In the mid-70's to
early 80's, 8080- and Z-80 systems ran on nothing *but* CP/M. Oh,
there were a few other also-rans, but they didn't amount to much.
Micropolis, for example, had its own OS (MDOS), for example. I ran
both CP/M-80 1.4, CP/M 2.2 and CP/M Plus (aka: CP/M 3) operating
systems, and, in fact, wrote quite a good deal of code for CP/M-80
systems, including contributing to the original XMODEM and MINICBBS
I ran one of the first, if not *the* first, 24x7 RCP/M systems in the
state of Michigan.
Nor was CP/M-86 vapourware. It was short-lived, because Kildall was
way too late to the game, but it did exist. IIRC, the DEC Rainbow
dual-booted CP/M-86 and DOS?
only the MP/M86
(multitasking variant of CP/M86) never had a real existence.
I think I ever only saw a single MP/M system in the wild.
Microsoft bought DRI,
Microsoft never bought Digital Research International. (Looking...)
It was acquired by Novell in 1981.
