The Casio 801P is one of several programmable calculators which were introduced in the early 80th.
Calculator? Or perhaps I should say early laptop? Compared to the mechanical calculators which were still sold in the early 70th this machine was a giant step forward. Equipped with an LCD display, a printer, a “mass” storage device, memory and lots of mathematical functions it more resembles an early laptop than a calculator.
The program memory size is 1680 bytes.
A small LCD display shows 20 characters in one line.
Programs can be stored on micro cassettes. Saving and loading seems to work reliably.
A small thermal printer prints program listings as well as calculation results.
Power source are either 6 AA cells or a 9V= adapter. Today’s rechargeable NiMH cells work fine too.
