Well, the first computer I can remember ever seeing was the one my dad used ...
I believe this is the correct one - but will have to ask him.

As to the first computer I ever had - high school, of course ...

In college - first DIGITAL computer -

A veritable orgy of sins and co-sins (*w*)
Four MEMORY registers, reverse polok logic. Saved my butt in college. Paid $250 or so, in 1974-5? - USED.
