z80 timing... 6502 timing

History ran a different course from where I sit. In 1985, the R65C02 was in
almost every new communications product I saw, e.g. FAX machines, though
many had a custom device. Those custom devices in many cases had a 65C02
core. Rockwell pushed it into those applications by making many of their
other parts "friendly" to the 650x core. The 805x was a mite slow out of
the blocks, and in '85, it was real but not appealing and certainly not
taking much business from the Z-80 or 650x because its price was still WAY
too high. It was, however, a single-chip device . . .

There's this old military saying, that "where you sit determines what you
see."

Well, that's what we're discussing, isn't it?
