Need datasheet for AMD 79C830 SUPERNET 2 chip ($$$)

Hi everyone. I'm looking for a datasheet for the AMD 79C830 "SUPERNET 2" chip. The only caveat is that it must be dated prior to July 1991. This will likely be a preliminary datasheet that was disseminated in limited volume. If you've got it, please contact me directly. I'll pay $100 for an actual lead but it must be in paper form. Digital copies might work, though it's doubtful whether one would exist.
