CASIO OH-82 super - Siegfried - 11-09-2023 08:26 PM
In case anyone is in need of Casio OH-82 super overhead projector calculators, some are sold NIB here for 5€ plus shipping.
I bought a pair as a curiosity as the overhead projector will probably soon be considered stone-age technology but I find it interesting that there was (is?) a market for such specialty machines. The transparent touch keyboard doesn't quite match the HP feel but is easier to clean.
