Some things are easy to check, like the fact that the Z80 came out in 1976 when
Woz was already finishing the Apple II so he couldn't have considered using it
for the Apple I.
I haven't personally looked into whether he considered using the Z80,
but your statement there is oversimplified.

According to a manual a friend has, the DECstation 220 outputs a diagnostic

As far as I know, there was no VM/360. There WAS VM/370,
which was out in the early 1970's, but
on 370 mainframes, not 360s.

There was VM/370 in 1980. I worked under it from May to August.
