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.
