I just bought one from System Technology Corporation (somehow, I seem to recall that they had something to do with Novy Systems, but anyway). They make a product they call the QuickMath/LC. It's just a single PDS card with a socket for the FPU and a socket for a clock. They will sell it populated with a 68882 and clock chip (the 68882 can run at speeds different from the CPU.) The default is no on-board clock, it just uses the system 16MHz clock. If you want, you can get a 20 MHz clock chip to up the speed yourself. I bought it for $149, on a special offer, but I don't remember what the regular price is. Note that the FPU is *socketed*. This is important, since you may want to purchase another board for a processor upgrade at some point in the future. Since it's socketed, you'll be able to pop the FPU out of the QM/LC board and put it in your CPU upgrade board. System Technology Corporation can be reached at (904) 428-0411. 1860 Fern Palm Drive, Edgewater, FL 32141. --jon P.S. I have no relationship with STC other than being a satisfied customer. -- -------------------------------------------------------------------------------- * Jon Whalen @ Notre Dame University Internet:j1whalen@handel.helios.nd.edu * * @ Tellabs Research Center Internet:jon@trc.tellabs.com * --------------------------------------------------------------------------------
