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. Note

Hello all,
I started with a VIC, I then got a C-64, C-128, A1000, A2000 which
I converted into an A2000T, the A3000T and finally an A4000T. I
eventually broke down and got a 486 machine and installed Win2000 on
it. Argh! I kept my A4000T for years after I got the 486. I networked

Such as Noel pointing out that I was mistaken in assuming that there was a
direct progression in 4004 -> 8008
Later it offered the C128, which had multiple operating modes,
including a much better BASIC and an 80-column display, but also an
entire incompatible 2nd processor -- a Z80 so it could run CP/M. This
being the successor model to the early-'80s home computer used by
millions of children to play

Thanks Liam. Oberon is pretty interesting. I may download that just to
see it in action. I’ve used a ton of 3Com cards so the setup program is pretty
familiar. I haven’t used DESQview, well, since I had it installed on my Compaq

He meant that PoSV is a fictionalised, sanitised, MS-approved account

As is MS' own history. Written by the winners, etc.
