I was there, through the 90s. It went from loads of science with a little bit computing to loads of computing with a little science. Was better at probem solving and coming up with multiple solutions than real science. So ideal for IT.
JCL, Fortran 77, Fortan 90, DEC and DCL, Cray
The best part was having access to Cray supercomputers. I could look at them, but was not allowed to sit on them. The Fortran code base for the global weather model was so massive and complex that DEC/Cray used it to QA new releases of Fortran compilers.
