Joe, That's ok! This isn't quite 50 years ago. When I was in high school=20 in 1973 we were time sharing across a 300 baud modem that was connected=20 to an IBM 370/70 if I remember the numbers correctly. Our programs were=20 stored on paper tape. I learned how to read the characters on the tape.=20 We were learning how to program in BASIC. Some of the students=20 discovered the Star Trek program and used up all of our processor time=20 in one night. They were expelled and the school had to buy some more=20 processor time so that the rest of us could finish our programs. The=20 computer room was locked from then on unless there was an instructor=20 there. Another example of the majority losing some privileges because of=20 what a few did. I don't even remember what program I was writing. I just=20 remember that we were studying BASIC. We were also learning FORTRAN. That was a lot of fun. We wrote out=20 our program and then transferred the program on to cards. I believe that=20 each card held 80 characters or one line. We then mailed the cards off=20 to UNR were they would try to compile it. We would then get our cards=20 back with a print out telling us where our errors were. We would fix the=20 errors and send the cards back to UNR. The turn around time was about=20 three weeks. None of us ever finished a program. Ten years later the=20 VIC-20 came out and wow I was in heaven. Thanks, rich!
