Hi Les, In a message dated 97-05-08 07:54:21 EDT, you write: << 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? It was either a SR-52 (1975) or TI-59 (1977). The first had a 100 step memory, the latter a 960 step memory. You could store programs and data on those tiny magnetic strips (guess they were like tiny floppies - except you turned the card around to read the second track)! Really great "micro-micro" computers. A terrific way to learn the thought process of efficient programming (once wrote a Social Security retirement program on the TI-59). What one could do when the bytes were few! John Hamilton hamijohn(a)aol.com "Life would be much easier if I had the source code ..."
