I remember writing a pretty complicated "guess the number" program in 16-bit DOS assembler in the 90's for a college course. It used colour and everything and I spent a number of long nights getting tasm to do what I wanted on my 486 I had at the time. Except the colour didn't work on the college computers because the DOS prompt was differently configured (I might have been using PC DOS, and college had MS DOS.) Fun times.
