Oh those were the days, I remember developing my first non-trivial piece of software (an international checkers game), while still a student, with Turbo Pascal. It run to more than a thousand lines of basically the Minimax algorithm plus various optimizations (alpha beta pruning, quiescent extensions, etc)

I have fond memories of the language, the IDE, libs like TurboVision, ObjectWindows, etc... And fun times with the demos TVChess and OwlChess, which gave me inspiration.
