Hardwarewise the CP/M machines were very diverse.  The most common
ones were the S100 bus computers and the Apple II with some Z80 card,
but there were also some quite oddball CP/M machines.  The only thing
they had in common was an 8080/8085/Z80 CPU.

OS-wise you could even get a real CP/M -- CP/M-86 -- to your PC in the
early PC days.  Actually you had a choice of three OS'es to the early
PC:
 
1. MS-DOS, delivered with the machine
 
2. CP/M-86, and later also CCPM which offered multitasking
 
3. UCSD Pascal
 
Alternative 3. offered an easy migration path to users of the Apple
Pascal system.
