I don't recognise the board per se. (sorry), but if you can describe
the memory connectors (pins or sockets?  how many pins?) a little 
better we might be able to help.  With that many of them, they
may well be "standard" 30-pin SIP/SIM modules.

If the board is roughly rectangular, put it in front of you, 
component side up with the short side with the I/O connectors 
facing away from you.

If the 96-way graphics card connector is now on the top of the
right-hand side, and the card plugged into it would be in 
the same plane as the board and adjacent to it, I would say
that the board you have is possibly from Sony NeWS machine,
perhaps a go-faster upgrade (as I seem to recall that the
original boards were unmistakably Sony work).
