Hi, I saw the post on the old calculator so here's mine: A buddy of mine used to work at a Salvation Army so I got a lot of stuff that they threw out. One was an old TI calculator that had these strips you fed in one side and a motor pulled them through (almost like a credit card reader) What is it? How old is it? Probably a TI-59. I recall owning a TI-58c and TI-59 calculator back in high school. In fact, I think I still have the TI-59, books and cards for it buried somewhere. If anyone is interested, I don't have any desire to collect calculators.
