Personal experience with an 80287 in an AT clone: make sure of
the speed with which the coprocessor socket is run. For
instance, if your main processor is run at 12 MHz, this does
*not* necessarily mean that your co should be a 12 MHz one
too. In my machine, depending on the motherboard version (damn
these clones, but if you're poor ...), the socket is run at 4
(!!!), 6 or 8 MHz. So buying anything with a higher number of
MHz'es is, at least partially, a waste of money (and your good
mood).
