6502, z80, 6809, BASIC, LSE, Pascal, COBOL, 360 assembler, S35 assembler, 68000, Microsoft Basic, LightSpeed Pascal, C, Modula-2, Object-Pascal, 8086, FORTRAN IV, Smalltalk, sh, csh, awk. Some to learn, some to work, some for a hobby. At work on that period, I've used 68000 assembler, S35 assembler, Microsoft Basic, LightSpeed Pascal, C, Modula-2. In the 90's personal computers became more powerful, internet became accessible, and therefore the gamut of accessible programming languages became much wider and much more interesting (Lisp, scheme, prolog, ML, Ada, Modula-3, Oberon, etc). But that's not your question.
