I had a bit of fun today and decided to test about slowing down my Pentium 3 1000Mhz retro pc. I am sure someone has already done this before but I still thought about sharing it with you.
First I slowed the cpu to 500Mhz in bios by slowing down the bus from 133Mhz to 66Mhz and disabled both caches and then I used throttle with command "throttle F" to maximize the slowdown. You need a chipset on motherboard to support incremental slowdown to use throttle like that.
Here are some results:
Basically I managed to make the original dos defender game from 1983 to be playable on a pentium 3 like mine. Defender usually requires a 4.77Mhz PC and is way too fast even on a 286. I didn't even have to use any TSR to get to this speed. Perhaps later I can find some other old games like this to test this more.
