What is the story with the necessary clock rate for an 80287 coprocessor?
I have a Leading Edge D2 (10Mhz), and the manual specifies a 10Mhz
coprocessor.  I have heard, however, that the math processors only
need to be rated at 2/3 system speed, meaning I could get away with
using a 8Mhz chip.  What have people been doing?
