Vintage Casio FX-501P Programmable Scientific Calculator around 1979

Vintage Casio FX-501P Programmable Scientific Calculator, dated around 1979, from the FX-501P and FX502P range. The calculator is in excellent'used' condition.

The box has a couple of tears and marks where it has been taped closed. The original holder for the calculator is in unused condition. I have tested the calculator with the batteries I have and it is in good working condition.

There are a few minor scratches/minor dents on the back of the calculator - too minor to show up on the photograph. The FX-501P and FX-502P were programmable calculators, manufactured by Casio from 1978/1979. They were one of the first LCD programmable Calculators tobe produced as up until 1979 (and the introduction of the HP-41C) nomanufacturer had introduced such a device. The extremely low power consumption makes battery life very long.

My original FX-501P lasted for years. The Casio FX-501P is a programmable calculator with 10digits precision and algebraic logic. The power source is 2 x CR2032 3V.

The calculator was manufactured in Japan. Featuring a single line 7-segment liquid crystal display with 10 digits as main display. An additional 3 digits 7-segment display used to display exponents and program steps when entering or debugging programs and 10 status indicators. The display was covered with a yellow filter. The programming model employed was key stroke programming, the instructions and special programming overlay card comes in the box.

The FX-501P could store 128 steps, with 11 memory registers and conditional and unconditional jumps as well as subroutines were supported. The FX-501P supported indirect addressing both for memory access and jumps and therefore the programming model could be considered Turing complete. What differentiated the FX-501/ FX-502P from its competitors was that programming was retained in a battery-buffered memory when the calculator was turned off.

The FX-501P used the FA-1 to store program and data to Compact Cassette (NOT included). Interestingly the FX-501P was used on the 1981 song PocketCalculator by music group and electronic music pioneers Kraftwerk, and the FX-501P is included in the list of instruments used to make their album "Computer World" and was also released as a single.
