[geeks] help identify this sun cpu?

[Dave McGuire]

   Hi folks.  I've just run across a "Sun SPARC CPU" on eBay that I 
cannot identify.  Has anyone seen anything like it?  At first I thought 
it was a 4/600 board, but look at the empty pads at the top of the pic, 
and look at the ejector handles and retainer screws...that is *not* a 
4/600, at least not like any other I've seen.  It seems to have an mbus 
module on it (but on the wrong side of the board for it to be a 4/600), 
and a strange, very long card in one of the sbus slots, but extending 
the wrong way along the board.

   Any ideas?
