I know this would basically be a useless feature, except for scientific curiousity. I think it could be interesting to some people to see first hand what sort of errors that old faulty CPUs would produce.

Emulators for other faulty platforms might be interesting too. Not like I’d expect any programmers out there to deliberately write faulty instructions though, except as stated, something of a scientific exercise.

Just curious honestly.

    Qemu, i386 target, not sure if they use TCG for that, they probably do, basically have a specific machine model that handles fdiv with a lookup table or something, honestly not sure how it went wrong.
