   I don't know about booting another OS directly from vtserver, but
I've successfully copied a BRUSYS image to RX02 with it, and booted
from the resulting disk. ISTR that there's also a method to make a
vtserver-bootable xxdp image, but I've not tried it.

   Heh. I've got SDI with functional RA60s and media, TU80, several
miles of tape, RX02s with exactly two(2) working floppy disks and about
30 pounds of 8-inch bulk-erased coasters, and a borrowed RT-11
v5.<mumble> install set on 8-inch media, except Disk 1 has about 3
critical corrupt files on it.

   I apparently own the licenses for both RT-11 v5.x and RSX11M on this
box (very long story), but the previous owner bulk-erased *all* the
storage media except the disk packs (and wrote zeroes, then trash files
then zeroes again, to the disk packs). Including all the distribution

   It's enough to make a grown man cry. I've got BSD running on it, but
frankly, I've got a metric assload of Unix boxes that are more
interesting as Unix servers and cheaper to run. I wanted something
that's unique to my PDP-11.
