Well, after hearing that the latest kernel supported the
exabyte 8200 (thank you!), I decided to bite the bullet and
upgrade from 1.1 to current. The hardware is an SS2 with
prom rev. 2.1. I installed everything but a new bootblock.

Here is what I saw:

Doesn't look like I should be worried, but what does the above mean?

Now comes the part I do worry about:

The kernel now thinks that esp0 targ 6 lun 0 is a regular
drive when it's really an old Sony CDU-8012. It worked in 1.1.

The other interesting new event is I now have a disappearing
file problem. On sd1, whenever I add or remove files, all the other
files in that directory disappear. If I unmount the drive, fsck, and
remount, no errors are reported by fsck, and the files are back. This
does not seem to happen on sd0. I know this drive works fine, or at
least I think I know. In 1.1 I moved around a large amount of data on
the drive without failures on a nightly basis.

Other then that, Netscape w/java works. What more could one want.

Thanks,
Jon
