 Scrounged a Mac SE motherboard+accelerator from a parts bin at RE-PC
 this afternoon and I'm trying to figure out what it is.  Unfortunately
 it looks like a few parts have been scavenged (a crystal oscillator and
 a few chips, plus the 68030+FPU) and there's a loose wire on the
 underside.
 I can't find any markings that give away its identity.  I have a few
 pictures up at 
http://yahozna.dyndns.org/scratch/mysterymac/.  Anyone
 have any ideas? 
There were a number of accelerators available back in the early/mid 90s.
For an identification like that and possibly to find someone else with the
same accelerator who can ID the missing parts, I'd try the appropriate
sub-forum over on 
68kmla.net.  That's 68K Macintosh Liberation Army.
