  SunOS4 will run on them.  SparcLinux at least used to, but only with
one board the last time I tried (several years ago).

  Do yourself a favor though...ditch them on eBay and get yourself a
nice pair of cheap, quick SM41 or SM51 boards.  You'll be glad you did.

  It's a DSBE/S...basically the differential equivalent of the
501-2015 (I think) FSBE/S board.  Most operating systems shouldn't be
able to tell the difference.  I've used 'em under NetBSD and I have a
friend who's using some under OpenBSD.  They seem to do fine.
