Okay, that looks correct.


This is sus.
According to my 6000-400 manual Table C-2

R5 Bit functions for Ultrix.
 Forces ULTRIXBOOT to prompt the user for an image name
(Default is VMUNIX)
 Boots the ULTRIX kernel imag in single-user mode.
Must be set and R4 must be 0
Must be set.

This is an Ultrix tape? You have threaded and LOADED the tape right? And
the machine is online?
The BOT, ONLINE and LOGIC ON leds are lit?
The error basically means the device you are trying to access doesn't
respond or isn't there.
I think you have the device name wrong, just looking in book to try and see
what it should be.
It doesn't actually SAY you can boot from a TU81, but it doesn't say you
can't either.

I don't think it has one, mine shows under VMS as ENIGMA$MUA0
That certainly how mine behaves. Have you tried to boot from MUA0 instead
of MU0?
The TK70 is CSA1 so that could be it.

Not sure what else it could be off hand, will have a closer look at the boot
flags, might be something special needed for tape.
Never actually done a tape boot, boot flags look sus for ultrix though.
