Hello I have a simple question and didn't find any answer yet. Does WINDOWS 3 make any use of a numeric coprocessor (80X87) ? In the \system directory there is a 87emu.dll, but I don't know what it does. I didn't notice any difference in speed before and after I had installed the 80287 either.

OS/2 has some other graphic primitives (like bezier splines) which might not be possible to write with integer math, so maybe OS/2 will show a speed increase. However, I think it's the applications under Windows that benefit. Obviously, Excel does. I heard that Pagemaker does too (can anyone substantiate this?) You probably won't find much of an increase unless you start running really large, math-intesive applications, like large spreadsheets, CAD programs, and stuff like Mathematica. ------------------------------------------------------------ The Time Traveler Your daddy works in porno Now that mommy's not around timur@seas.gwu.edu She used to love her heroin HE891C@GWUVM.GWU.EDU But now she's underground - Guns N' Roses
