Back in the day, Intel made 386DX chips that ran up to 33MHz. AMD came
out with a clone chip in the 1990-1991 time frame that was a 386DX that
ran at 40MHz. I ran a 33MHz rated ITT 387 clone mathco in mine without
problems. IIRC, the ITT mathco didn't perform quite as well as a real
Intel one, but it was better than not having anything.
I know Intel still has a rather large 80386 embedded processor market,
so I'd not be surprised if they're making much faster versions of it now.

I'm
trying to track down a 387 math coprocessor IC for an old 386-based
Linux box that's going to be doing a bit of numbercrunching for me. Has
anyone here got an AMD or Intel (AMD preferred) 387 coprocessor rated at
40MHz
40 MHz? I didn't think they made them over 25 Mhz. I have a couple
around here but I'll have to dig them out. However I'm pretty sure
that they're 20 and 25 Mhz.
