Programmable calculator with 10+2 digit precision.
This calculator has quite a load of functionality. It can store four programs with a total of 128 programming steps. It can produce a series of mathematical constants using 'INV' 'OUT'; they are listed at the top right of the calculator. Furthermore it does statistic and BASE-N calculations, and can handle complex numbers.
Concerning its programming, it is keystroke programmable with the addition of flow control using comparisons and 'GOTO'. Once entered, a program can not be edited however. There is no way to step through a program to make corrections.
According to this thread (link valid 2023-08-12) on The Museum of HP Calculators (link valid 2023-08-12) there are multiple versions of this calculator by multiple brands. Unclear which brand invented this calculator. My guess is Canon.
The list so far:
