[SunRescue] Identify?

[Shock]

Can anyone identify this motherboard #   501-2286?

I have found a large quanity of what appears to be some generic clone Sparc
5's. But they have no place for CDROMS and use a 50pin SCSI connector. THey
also apear to use 168pin DIMMS. There are 3 SBUS slots and the back of it
looks like a Sparc 5. What the hell are they? Anyone know?
They use the Fujitsu MB86904 microSparc II Processor
