Hah, while I had a 386, it was an SX, as in without a math co-processor. I managed to find a TSR program on a local BBS that would emulate a math co-processor though, allowing me to play Doom.
It was not a playable experience. Even at the smallest screen size, it still ran at about 1 FPS.
But, I was playing Doom!
- mlyle 3y agoMaybe it was Quake. Doom didn't use math coprocessors.
- mrob 3y agoDoom used fixed point math, not floating point math. It didn't run well on a 386 SX simply because 386 SXs were slow, but it would run without FPU emulation, and at better than 1 FPS.
- mjg59 3y agoThe dx didn't have an FPU either - the difference was the size of the data bus (sx had a 16 bit data bus, dx was 32). It was the 486 where the sx/dx notation indicated floating point support.
