Very rare old machine, probably made in early 1967. I can't recall ever having seen a LOCI calculator on eBay in all of the years that I've watched it for old calculators. This one is a pretty early LOCI-2, with keyboard keys with molded-in legends rather than the paper legends with clear plastic keycap covers. Both of the LOCI-2's in the Old Calculator Museum have the paper-legend keyboard. This makes the machine at auction even more unusual. The LOCI-2 was only programmable via an external punched card reader, which does not seem to be included in this auction. It doesn't have any program storage or learn-mode capabilities -- it just reads program steps from the card reader and executes them. Without the card reader, it's just a stand-alone calculator. Based on the photo and description, my guess is that it is not fully functional. The machine uses mostly 2N404 Germanium transistors for the logic, so it's possible to repair as these transistors are still available (although somewhat expensive). It looks like it has taken some pretty good hits during its life, as the upper part of the cabinet is pretty banged up. It is all there, though, and would definitely make a great addition to any vintage calculating/computing collection.
