I remember the last week of my 8 week COBOL course in the Marines in 1993. We'd written a COBOL program each week, then in week 8, we re-wrote every one in JCL. Just for the nostalgia, my second computer was a Commodore 64. I don't remember what the first one was, but it was a keyboard, a coaxial cable that plugged into the tv, and cartridges with some games on it. Came with a BASIC interpreter, but if you wanted to save the program you were writing, you had to buy an external tape drive (as in cassette tapes).
