I'm going to date myself here. In 199x, we had a 286 and loved a game called "Command HQ" that had lovely gameplay and sound to boot! Then we got the ol' Packard bell 486 with a sound blaster. We played the same game (which had midi output too) for the first time and my father and I cried -- it was unbelievable.

That's when I first became enamoured with the "art of the possible" and this has driven my career.

I fully believe that doom could have had pc speaker sound; after all w3d did!
