Hmmm, something must be wrong since nothing happens after five minutes.
I'll put the machine aside and work on it later. It's part of the pile of
DEC gear I must get rid of anyway. List of which will appear here soon.

I didn't mean to say RT was on any of the disk packs I tried to
bootup.Truthfully, I do not know which: RT-11 or RSX-11M as the bootable
packs were not marked. I did try a couple of the RSX-11M Distribution packs.

I've tried at least a half dozen packs some of which are bootable as
mentioned above. Exact same results.
