[comp.sys.ibm.pc] '387 coprocessor emulation.

peraino@gmu90x.gmu.edu (peraino) (02/27/90)

Greetings;

     Some 386 PC's seem to have a way to emulate the '387 with software.
I have a ps/2 model 70, and am wondering how I could accomplish
this. I realize that it would be slow, but I have a few packages that
require the use of a coprocessor, which I don't have. If anyone could
help me, please respond directly to me, since I don't normally read this
group. Thanx much.

I have a shareware program called EM87 that does a pretty good job of 80x87
emulation.  It only works on a 386/387.  It runs software like a 8 Mhz 8088
on a 20 Mhz 386.  For light duty applications it is OK, but Autocad 10 will 
lock it up with not to much trouble.  Nothing really substitutes for a
coprocessor for floating point intensive applications.
