Does anyone know what the Radius SANE init does besides (apparantly)
dramatically increasing the speed of the 68881 in my Mac II?  A
friend of mine recommended it and gave me a copy saying that it
more than triples the math computations.  A Software patch of some
sort.  I also borrowed his shareware program, Speedometer 1.1 to
gauge the speed increase and these were the results:

Test:				Results w/out		Results with
--------------------------------------------------------------------
KWhetstones/sec			52.174			167.131
Dhrystone/sec			2564.103		2568.493
Sieve				1.383			1.383
Savage Cum Error		3.0444e-0111		2.29e-0111
Savage Time			48.45			4.583
Savage Iterations		5000			5000
CPU Speed (1=SE?)		3.38			3.37
Math Speed			6.68			25.56
Disk Speed			3.31			3.31
Overall				4.02			7.80
---------------------------------------------------------------------

System is a Mac II, 6.0.2/6.1, No Multifinder, 140 Meg Rodime,
more inits than I can count, 5 Megs RAM.

If these results are true and hold for all math intensive applications,
this really is a blessing.  Does anybody know anything about this?
The copyright date on this init is 1987, and is version 1.2.
