First programmed in BASIC+ in 1975 on a DEC PDP-11 RSTS via 110 bps acoustic modem; since then, FORTRAN IV, Pascal, and PL/I on System 360, HP15C (implemented LIFE in 512 bytes RAM), (briefly) BASIC on a Tandy Pocket Computer, BASIC and (very little) assembler on Tandy Color Computer (64k to 512k), Basic, QBASIC/Quick BASIC, Modula-2 and C and (very little) assembler on DOS 8088/80286/80386/486SX. Now working on re-learning C after 20+ years, while simultaneously learning Python -- so far, so good.
