An early handheld calculator from 1974, with a 10 digit Panaplex display and rechargeable battery.
As I continue searching for Monroe 400 series calculators, I came across this Monroe model 40 calculator at a reasonable price, with a few small issues.
Normally I don’t have an interest in handheld calculators as most are too new. This one caught my eye with it’s unique styling and 10 digit Neon Panaplex II display.
