Bzzzt.  The Solbourne workstations are far different than Sun's SPARCstations
and don't run NetBSD.  End of story.

The Solbourne OS/MP 4.1C, while based on SunOS 4.1.3, is also quite different
to accomodate the not-insignificant differences in the Solbourne hardware vis
a vis Sun's.

If you want to try porting NetBSD/SPARC to those Solbournes, well, good luck.
Maybe Warner Losh is out there somewhere and could offer some advice; but I
suspect it would be more like sympathy at this point.  You've been saddled
with dead-end hardware.
