My last post on the subject.  I used such a calculator back in high school
(which would have been around '67).  It used nixie tubes as its display
(remember those?).  I don't know if it was made completely of discrete
components; ICs had been around since the early '60s, and I know there were
logic gates, adders, and such around back then.  No MPUs (microprocessing
units for those of you who are still being licked into adult form), but
primitive logic circuitry.  BTW, the calc I played with was made by H-P I
think, so they might have some info on it on one of their websites.
