It requires *bunches* of bank select memory, but I distinctly remember
seeing a friend run Cromemco's CROMIX on a 4MHz Z80 cpu (I think it was
a Cromemco "ZPU"???).   Don't remember much about performance or function,
however.

Three vampires walk into a bar and the first one says to the bartender,
"I'd like a pint of blood."  The second one says, "A pint of blood for
me too."  The third one says, "Make mine a pint of plasma."  The bartender
says, "Let me be sure I've got this right.  That will be two bloods and
a blood lite?"
