without modification, in most cases, on a Z80,.by the
time the 6502
became
popular. Now, I've always believed the 6502 at 1
MHz to compare
favorably with
the 4 MHz Z80, but I used the Z80 running CP/M 2.2 to
do useful work,
since it
was a lot more trouble squeezing useful work out of a
6502 back in
'78-'79.
If anything I'd say CP/M was a factor more than any virtue of Z80. I say
that as
most "z80" code underused the Z80 as a fancy 8080. One may wonder if a
cp/m like (or better!) OS existed for 6502 such that it was portable or
easily
ported if things may have developed differently.
