Since I have no way of having a chip of 80's
technology made I have to
limit the design to what looks realistic for that era.
I dont get that? You want a 4mhz z80 or 5mhz 8085? Those are relatively
common. Now, if your doing PDP-8 era then 1.2uS instruction cycle was
the number, slow by todays standards.
This is what this is -- a hobby/ learning tool --
In the early 80s, I really was trying to do what zilog eventually did,
make a Z280 more or less. That and figure out what this ucode
thing was all about.
If it was $$$ making I would have to move to Seattle.

Now that's depressing. ;)
