there is also the Z80H...
2.5 mhz, 4mhz, 6mhz, and finally 8 mhz
replacing with a faster z80 should not pose a problem. It should
actually relax the timing a bit and work more reliably depending
on the original design.

I have seen z80, z80a, and z80b processors, and I'm curious about
what the
differences are between the different versions of the
processor?
Is each
newer version faster than the earlier model, like a
486-33/66/100
or are the
differences more along the lines of additional commands
(or
something like
that?) Or a combination of both?
Also, can I use a Z80a or Z80b in place of the original Z80
if I want to
replace a bad CPU?
Thanks.
