I programmed in PET basic in 1977/78 on my PET 2001 computer with a tape drive. Oh, the memories! And trying to explain to my mom and dad what the large thing on my desk was, and what could you do with it. Dad would bring up Colossus:The Forbin Project (the 1970 movie, which I saw a few years before buying my PET used for $832 in NYC).
