I find myself greatly amused at the idea of a VAX 11/750
booting from a
"modern" computer whose sole purpose is to emulate a tape
drive.

I went to the auction when Delta Airlines shut down their flight
sim
training facilty here in the Twin Cities. They had a Link/GP-4 machine
that must have been 10 racks of TTL and analog stuff - hooked up to a
PDP-11/45 that I didn't win at the auction :-( Anyway, it must have
originally
had drum memory. In one of the racks there was a 1U piece of
gear that had the
label "DRUM EMULATOR". It looked like nothing more
than a 3.5" floppy drive
with some logic behind it.

I was able to save the console panel for this guy
from the scrappers who
were dismantling it when I went to pick up the stuff I
did win. About 70
pounds  of buttons, lights and dials.
