you have photos
and/or more details?
No photos. Sorry, I didn't have an iPhone when I was a college freshman
in 1965. I never saw one, anyway. We got by with Monroe and Friden
mechanical calculators, full of gears and cams. One of them could even
do square roots.
I am familiar with the first HP desktop calculator
(9100A) that
inspired their first handheld calculator (HP-35). The HP-35 was a
ten-digit calculator that was released in 1972 for $395.

901B is the first pocket calculator I remember -
I don't know if
there were earlier ones.
The first one I remember is the HP Digital Slide Rule, about 1965.
Six digits. $600.
