IIRC, Autocad *requires* a mathco, so one has a choice of a) buying a mathco
(used to be $$$), b) running with an emulator, or c) not running autocad.
As to whether the system will run faster with or without a software mathco
emulator, I must admit, it would seem obvious that an emulator would only
slow the system down (by using more Cpu time to handle the emulator than
going straight to the CPU -- kinda like buying direct from the mfr and
eliminating the middleman) but I cannot say that that's true without testing it.
The FRANKE87 program may be really good at what it does, enough to make a
difference when compared to Intel's idea of FP math. I have to say that if
Merch says he measured the difference and the emulator is faster, I'll take
his word for it until proven wrong.

2) I saw
several emulators, but the only one I found that actually worked
well, the file was called "FRANKE87" and was German in origin. It actually
fooled AutoCad 10 into believing there was a co-processor chip on my 386SX
and actually did speed up FP instructions (measured with CheckIt).
Not. Autocad is
processor heavy program and better unload that FP to
that coprocessor result in even powerful system when using the
suitable s/w like autocad.
