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.
