parts was
2.5MHz (4MHz for Z80A and 6MHz for Z80H).
Just a minor correction. I believe the Z80B is 6MHz and the Z80H 8MHz.

Zilog always listed the 'B' part as 6 MHz and the 'H' part as 8.

I've never seen a Z80H specified as anything other
than 8MHz.
By the way, what happened to the letters C to G?

Do ST make Z80s as well as 68000s? How unfaithful.
