I bought a big box'o'parts for my SGI Challenge L a while back, and there's
one board in the bunch I can't identify.

I thought it was a processor board, a 2-processor version of the quad-IP19
already in the Challenge, but, now that I finally compare them, I see it's
completely different.

The one in the Challenge is marked "IP 91 ASSY 030-0375-009 Rav A" along the
top edge.  It's got 4 processors, four groups of SIMM-like memory, etc.

The mystery board isn't marked along the top, but has a small sticker saying
"030-1107-101 Rev A" on the board, and "1107-101/A" on one of the locking
handles.  It's got two processors, two blank areas marked "CPU2" and "CPU3",
no SIMMs, and a completely different layout.

part number.

Googling the number hasn't turned up much, but you guys are better than
Google when it comes to this stuff.  Clues appreciated.
