Sharp CSA-12 "Memorizer 60" Programmer Manual
Front cover of Sharp Memorizer 60 (Model CSA-12) Automatic "Programer" Operating Instructions
The Model CSA-12, called the "Memorizer 60", was an accessory that could be
connected to a Sharp Compet 22
or Compet 32 electronic calculator to allow these machines to be "learn mode"
programmed. Programs were "learned" from the keyboard of the calculator, and
stored within a core memory array in the Memorizer 60. Programs of up to 60
steps could be stored. The Memorizer 60 could them "play back" the stored
steps at high speed, to allow relatively complex math operations to be
performed. Note the misspelling of "Programer" on the cover of the manual.
