Actually, there were 4 Z8000s: Z8001 and Z8002 were the first pair, with the 8001 having extra pins to address more memory, and the 8002 addressing 64K memory.
The Z8003 and Z8004 were VM machines, same packages as 8001 and 8002.
I used the Z8002 in a robot controller; VERY nice, and I sure wish IBM had picked the Z8000 over the 8088 !!!

Actually, as I see it, Gabriel's point is that you -cannot- get to "100% perfection" by hacking like mad on an inadequate design.
And this explains why design (Cathedral, if you will) is so important.
