How does the Sun 2/50 then mount partitions ? (or were you using
SunOS 5 on the 2/50 and using NFS to mount parittions) ?

There was no SunOS 4.1.3 kernel for Sun3. Sun stopped support for Sun3
at SunOS 4.1.1_U1 (or was it 3x that stopped at 4.1.1_U1 and straight
Sun3 at 4.1.1 Rev B ?).

possibly a fuse ? maybe some boards didn't have everything required to
make that work... dunno as I don't have a 3/60.

Your hard disk to install on should be target 3. SunOS oddly maps
sd0 to target 3, etc... (if you have any running SunOS system that
hasn't beem modified look at the kernel conf file you will see the
sd and st to id mappeings in there.... it's the same for most if not
all SunOS 4.X releases).
Another thing to keep in mind... is sometimes you can't just 'plop'
newer boot roms into a board.... sometimes there are ECOs required
(like with the Sun 3/80 going to 3.03 ROMs).
