   Already done. I had enough trouble reading the tapes (a lot of the EOF
markers were gone, so I got big globs consisting of several tars that I had
to separate manually) that I burned them all onto CD-R when I did manage to
get it all straightened out.

   I ran a 2/120 for years on a Fast SCSI-2 drive. I did get the occasional
SCSI error, but I think that was the drive's fault. When the errors
eventually got too bad, IIRC I tried the drive on other systems and it
wouldn't work correctly on those either.

   Oh, that's another thing about Sun-2's: recent versions of gcc (2.7.x
and maybe 2.6.x, I don't remember anymore) may generate bad code for the
68010.
