For one, I hadn't known that CP/M was written originally to the 8080.. I'd
always assumed it originated on the Z80.
There are only 8080 instructions in CP/M, not a single Z80-specific
instruction. CP/M came about around 1974, the Z80 in 1976.
All the CP/M computers I used had a Z80, but that's just shows what
was popular at the time.
