Do, please.   I remember seeing them about 3 years ago when I got my
first VAX (a 3500 that we blew up before we knew any better), and have
used 3100 class boxes ever since.  But, now that I have a MV3300 to
worry about, too, I probably do need to find out what specifically
those symbols and switches mean.

Mine does.... MV3300.

If that is the same cable that is in my MV3300, I will look into it when
I get home, tonight, since I have to open it up for the ethernet port
switch lube job.  If it is not, well, sorry.  Where should the number
be on that cable (a white barrel wrap tag?)?

IF I can get my ethernet port working, I will offer my box as a guinea
pig for testing.  I will have to use TK50 or ethernet to boot, since I
don't have any way to run scsi on it, yet.  If I can get it going from
an Ultrix boot, I could set up the second HD as a NetBSD test drive.
Since the TK50 tape boot is independent of the scsi bus, could a standard
boot tape from 1.4.1 or 1.4.2 be used to boot the thing into a ramdisk
kernel, and then load from ftp (if my ethernet works) or tape?  I have
not thought to try that, but logic would suggest it ought to at least
come up into the kernel even if no scsi devices were found?
