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?
You are asking very weird questions.
What do you mean by "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).

Did the C64 not run CP/M? I know the 128 did. It had a 8502
processor and Z80A processor I believe. One was for CP/M. What
good is a commodore machine without CP/M ;)
