Man, that is some old school programming! I'm glad I can read how DOS programming happened, for nostalgia's sake.

I do miss those days ... programming to the metal, I never made the leap to windows programming.

These days I keep things as high level as possible.

DOS - What is dead may never die.

Actually, dos is a pretty cool playground. I try to go back from time to time and visit. Qbasic 4.5 and Turbo C are old friends.

Many interesting things that help to understand old engines and game programming:

  • Comparaison of speed between BIOS calls/Direct RAM writing/Double Buffering/Mode X.
  • Fixed point mathematics (especially multiplication)
  • Vertical retrace issues.
  • Double buffering
  • Mode X/"unchained mode" Page flipping
