Here's a snippet of info that might or might not be useful as an addition 
to the next update...

I have successfully used a modified Toshiba 3301 with this machine when it
was a 3/480 running SunOS 4.1.1u1, which was the same Sun-3x kernel
release as a 3/80 would use. I never tried the drive with a 3/80 though,
and the usage with a 3/480 was limited to pulling SunOS 4.1.4 release tar
files off a 4.1.4 CD so I could install the new OS for the 4/280 Sparc CPU
board that eventually replace the 3/480 board.

The CD-ROM drivers gave continual errors if the machine was loaded at all,
which showed up in the console window. I presume the drivers in 4.1.1 were
very virgin and largely untested at that stage in development (around
1990), but since I've moved almost exclusively to Sparc machines running
4.1.4 there's been no trace of the problems experienced on the 3/480. 

The 3/80 would have quite probably given different problems if I'd tried
the drive with it because of kernel code differences resulting from the
3/80 having an ESP SCSI chip while the 3/480 had a Sun-3 VME SCSI card
that used an NCR 5380.

Unfortunately for a Sun-3 or Sun-3x user, upgrading to SunOS 4.1.2 isn't 
an option. 8-)

I hope this information is useful.
