They come up on epay all the time, pick yer flavor. I just got a 40MHz
Cyrix Fasmath chip for $2 (includes $1 shipping) a week ago. Supposedly
clock for clock it's the fastest of the '387 FPUs, but IDK. Popped right in
to to my P70.
I'm still looking for a set of eight 2MB 72 pin IBM SIMMs with presence
detect, and a Cyrix 486Drx2, which is a 486 with a '386 pinout, if anyone
has a spare.
