Many had 1MB (such as the 142MHz).  The double-width card looks like a
FDDI or CDDI board to me, though I can't be sure.  There's no mention of
it in the bootup messages, though a cgsix is mentioned.

This could well be a prototype, though the heatsink on the module in the
picture looks like an older style.  Some close ups of the module would be
really nice to see.

Interestingly enough, there's a 2MB PrestoServe VSIMM present in both the
picture and the OBP log.  You can just see the side of the (yellow)
battery on the end of the SIMM.

FWIW, this system is probably on par CPU-wise with a fast Ultra 1.  It's
probably not worth the $450 for raw power, but if you're into collecting
Sun-related oddities...
