Cyrix FasMath EMC87

[Komz]

Hi All,

What's the diference between Cyrix FasMATH for e.g. CX-83D87-33 GP and CX-EMC87-33-GP. Both are 33 MHz version, but what about this "EMC"?

I've got this one and I think that's very funny - chip marks are rotated by 45 degrees

Karolo,

Very nice chip you've got there! This is from Aad Offerman's CHIPLIST:

Very detailed explanation of EMC87 features (I hope this URL works):

It combines the best of both worlds. x87 and akind of weitek programming. Only AutoCAD made a real use of it.
