It's not every day that I post a backlog of as many as 12 calculator images (all thrift store finds from the past few months; none are programmable, though):

  • Two Aurex 108i scientifics, a red and a blue one.
  • A large-digit basic calculator labeled CORA TK-400.
  • A Canon F-605G.
  • A Casio fx-300s, not exactly in great shape (heavily used) but functional.
  • An HP 10bII, with a faulty display... oh the shame! Once mighty HP using the cheapest Asian manufacturers I guess, using the same unreliably zebra strips that you find in dollar store budget calculators...
  • Two no-name scientifics, one black, one white.
  • A Sharp EL-540 (oldie but goldie) And a far less common Sharp EL-738 (business/financial).
  • Last but not least, two more variants of the all-time classic from Texas Instruments: A TI-30Xa and a TI-30X IIB.
