You're kidding, right? You never noticed the CRYSTAL(!!!!) on the little
daughterboard that holds said 80287??? I specifically said, you can feed
the numeric chip its own clock if you want to; and yes, the 8087's execution
unit can also run asynchronously with its control unit.

Geez Louise--plug the chip in to 5VDC and off it goes at 10MHz...wait til
the crystal manufacturers find out about this...mutter, mutter.
