My High School math department had a mechanical calculator. Punch in
the numbers and it worked them out on a carriage that went back and
forth like a typewriter.
Natuaraly after school, I told it to diviade by Zero.... Ran for quite
a while before I figured out the way to stop it was to power off, punch
some keys to jam it, power on and press clear.
I used to do my taxes on an Toshiba 14 digit printing calculator that I
got at a government surplus sale. It had been used for a promotional
coin program for the 76 Montreal Olympics judging by the stickers on the
back. two large circuit boards filled with (Toshiba Naturally) TO-5 ICs
no display just a small drum printer. Has a nice keyboard, magnets in
the keys work magnetic reed switches.
