I remember those floppy drives where big and heavy. I never had cp/m or a c128.
I am reading that an 8502 and Z80A (which I can't find anything on) was inside.
The Z80A was about 4 MHz. The Z80A word size I do not know. It was of course an
8 bit with a 16 bit address bus I believe. Now which is "memory word" size?

The C64 did not run cp/m out of the box, because it did not have any kind of
Intel 8080 based processor. You could buy a cartridge (iirc) that would allow
you to run cp/m, but it was basically bolting a cp/m machine onto the side of
the C64.
The C128 had both the C64 processor, and a Z80 processor built in, and it
could run cp/m. The floppy drive speed was really lousy though (300 baud serial
bus iirc).
