@Alyx I THINK what the deal was is that typically this was around the time when the maximum speed of a pc was like... 25 mhz or something. maybe 66 tops... So I guess to preserve cpu lifetime (because most chips didn't need/use heatsinks or fans and were okay with passive cooling from jsut their surface) they underclocked the cpu by default, sothe cases often had a Turbo Switch that would ramp it up to full speed??
@Nine oh shit I remember now, the very first PC clone I had, this crap 386 box that was like about 10% as useful as the Commodore 64 it replaced, had a turbo button
I would push it sometimes. I don't remember feeling like it did anything
