Busytron HANDY 80S


Brand: Busytron
Model: HANDY 80S
Type: Calculator
Picture: Busytron HANDY 80S
Batteries: AA x 4
Lifetime: Introduced: unknown
Terminated: unknown
Notes: Judging from its looks I would say that this calculator is probably a commodore clone, however I have no idea of which calculator.

This calculator has the basic functions, percentages, square roots and some extra's. The "RE"-key is a sort of "repeat calculation" key. For instance after performing a calculation of, say, "x + y = z", the "RE" will perform "y + z =".

I couldn't find out what the "D"-key does.

There is also a quite common bug in that this calculator thinks √-9 = -3.


A power adapter.
