  I remember that book! I wanted to get a copy but made do with the DOS Programmer's Reference, 3rd ed., which was also very good since beej's interrupt list wasn't available yet or I didn't know about it.

      Yes, Ralf Brown. I guess I'm getting old.

        I found a copy of the PC Game Programmer's Encyclopedia (PCGPE) back then but couldn't really wrap my head around most of the articles (especially the 3D stuff and Mode X).
