I don't remember exactly what the program was, but it was on this this thing that looked like a big adding machine (remember those?), and was probably one of the first programmable calculators. We had to hand punch the cards with paper clips and feed'em through the card reader to get our program in. It had about 4 or 7 registers we could store variables in. I'm sure one of the first programs just counted numbers and printed 1,2,3, etc., and maybe a later one found prime numbers or something.

First semi-significant program in a real programming language was a text-based Star-Trek game written in FORTRAN, on a Dec-10.
