I learned FORTRAN in 1965 on a CDC 3100. Real core memory, tape drives, vacuum drum card reader, Calcomp plotter. Super slick. I took a computer science course at Dalhousie University in 1970, used a CDC 6400. My professor was obsessed with pseudo-random numbers, the 60-bit word size was a godsend.
