	SysEnvirons (v1 and 2) in System 6.0.2 and later will return hasFPU TRUE
if either a 881 or 882 is installed.  This was not the reason that Excel 
fails, it is becuase Excel does not use SysEnvirons to test, it does its
own testing for the 881 and that test fails for the 882 in the IIx.

	Anything is possiblie, though currently I don't see why you would need to
know whether it was an 881 or 882...
