On an IBM 360 mainframe at my University. First using SPSS to look at 15th century tribute lists from Yucatan, then bringing the college mainframe to it's knees in an experimental computer mapping course. We were assigned to do a fishnet of 10 data points. I did an actual map (Fortran) of the state of Yucatan (outline and 101 municipios). It didn't work in the 4k students were allocated. We looked for errors and found none. Finally they shut down all of the admin programs and let mine run full out over one weekend and it worked. Now I have more power in my phone:-)
