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 BASEN 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.

Unclear which brand invented this calculator. My guess is Canon. The list so far:
