I would like some information on coprocessors. I keep seeing references to a Weitek math coprocessor. Is this equivalent to an Intel 80387? Is one better than the other (faster, more compatible, whatever)? Is one cheaper than the other? Any personal experiences would also be appreciated! Thanks, Ty A.

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). --- Regards, Jaap.
