Differences in the Z80 processors?

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.

best regards, Steve Thatcher

I have seen z80, z80a, and z80b processors, and I'm curious about
what the

Is each

or are the

something like
