x86 did not have an included FPU until the 486DX. 386 and 486SX supported an optional FPU (80387 and 80487). So emulating a 286 shouldn't have to worry about FPU at all. But as DaveC said only a handful of MHz are probably realistic.no_skill posted on Sep 30 2005 at 02:12 PM said:dos box
knowing that the dos box emulates a cpu stronly relying on floating point operations makes this look even more insane.
I don't think PSX has FPU either... however it has a lot of custom hardware. Hardware 3D assist (Geometry Transform), Data Decompression Engine, 2D GPU (sprites, rotation, scaling, etc), and a sound processor. (See http://en.wikipedia.org/wiki/PlayStation)
