The IBM 1620 computer from 1959 was billed as an inexpensive system for scientific work. Interesting machine from an architectural standpoint, having variable word length decimal (non-binary) words, and using memory lookup tables to do addition and subtraction rather than a dedicated arithmetic logic unit (ALU).
The lack of hardware for basic math functions earned the machine the nickname CADET :
“Can’t Add , Doesn’t Even Try.”
