Mystery Motorola Chip SC80951S

Every so often, since the beginning of the "interweb," I've wasted a few hours scouring the vast stores of information for a glimmer of data on the Motorola SC80951S chip. All I find are the part pimps peddling them for sums which they'll only disclose if you file a formal RFQ. No datasheets or even a simple description of the part's function can be found anywhere. I amuse myself by wondering if I had somehow acquired some super secret component that played a crucial part in the downfall of the Eastern Bloc. Eventually reality kicks in and I realize it wouldn't have a Motorola logo on it if that was the case. So here I am, before what probably amounts to the most comprehensive brain trust in vintage compute technology, to ask if any of you folks know what this thing is. Here is a link to a photograph: http://www.aximel.com/files/SC80951S.jpg Though I could not focus close enough to get a picture of the wafer, it appears to have some regions that suggest an EPROM memory array, some smaller regions that might be SRAM, and various other complicated looking shapes that may just be a CPU of some sort. I'm mostly interested in learning what it is. But if you can find me a data sheet I'll gladly share half a dozen of them with you. :-)
