I only used the 1130 in college. Started with FORTRAN and Assembler, then COBOL. This was 1973 - 1977 at Lawrence Institute of Technology (aka Larry Tech)
I also used the 1130 while in college, from 1967 to 1972. I avoided COBOL and RPG since I was headed for computing close to the metal. So, I made electronic devices that hooked to the computer and then wrote device drivers and applications for a nuclear physics lab.
