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
The only difference berween those processors is the maximum clacok
frequency you can use :
Z80 : 2.5MHz
Z80A : 4MHz
Z80B : 6MHz
Z80H : 8MHz
There are, AFAIK, no extra instructions in any of the versions.
Also, can I use a Z80a or Z80b in place of the
original Z80 if I want to
replace a bad CPU?
That should work fine
