i was never a turbo pascal user, but my first real programming environment was borland's turbo c, a close relative. it had a great debugger that would allow you to run your app on your primary color monitor, and display the contents of the turbo debugger on your monochrome display. turbo debugger was also great for single-stepping your way through other people's programs in the same way. back in the day, i wrote a VGA-based game that, if it detected a secondary monochrome display, would put up a whole bunch of real-time-updating graphics statistics on it. that made performance tuning a lot easier.
