EM87 V1.3	2/10/89
			=========

	This program fully emulates the 8087 math coprocessor on 80286 
and 80386 based computers. This is useful to run software that requires
the 8087/80287/80287. This program does not emulate the 80287/80387
extensions to the 8087 instruction set, but all software I have seen
only uses the 8087 instructions to be PC/XT compatable. Please note that
floating point emulation is MUCH slower than the real thing (but also 
much cheaper!).
	Unfortunately, this method of emulation does not work on the 8088
and 8086 based computers because these processors do not have emulation
support built in.

History:
	Version 1.1 fixes problems with programs that access extended memory,
like VDISK.SYS, RAMDRIVE.SYS, SMARTDRV.SYS, AUTOCAD, etc. Also this version
will not load if a real 80X87 is present.
	Version 1.2 fixes problems uninstalling EM87 under certain versions of
DOS. Also display of the help screen would lock up some machines.
	Version 1.3 allows floating point exception interrupts to properly 
cause a non-maskable interrupt when enabled. Very few programs use this feature.
The lack of this capability caused programs that needed it to do strange things
to the video display.

Tested with:
	AUTOCAD release 9.
	AUTOCAD release 10.
	Microway's 87TEST v1.20 (A very intensive 8087 test program).
	FATMAN30 (A great mandelbrot generator!).
	NORTON UTILITIES 4.5 SI (Reports a 8087 present).
	PC-Matlab
	Simnon

Usage:
	EM87		>Display the help screen.
	EM87 /L		>Load the emulator.
	EM87 /U		>Unload the emulator.
