I am now dangerously close to getting 2.11BSD on my 11/44. ^_^
I got a SCSI disk controller (Viking UDT) and TS11 tapes, and 16 ports of
DZ11s (Anyone got jumper/DIP switch info on these?), but my problem is
lack of a boot tape.
Anyway, since I have other machines around which can grok SCSI disks, I tried
making an RP06 image on Supnik's emulator, installing the rauboot instead of
hkuboot, but it failed. The PDP-11 read the bootstrap in OK and the bootstrap
was running but it was looping (I forgot the address).
Has anyone done this before? I would use a SCSI tape to boot from but the
SCSI tape drive I have died. (Roached literally - one of the little fsckers
got inside it and got fried.)

Are you sure it was a RP06 image? hkuboot is the RK06/07 bootstrap.
How did you move the RP06 (or RK06) image to the physical SCSI drive? You
were asking about doing it with RT-11 a few weeks ago, but you *do*
know that RT-11 won't conventionally access the 65536th (and
2*65536th, and 3*65536th...) blocks on a MSCP partition, don't you? (There
is a way of accessing that last block, but you have to code it with
a .SPFUN call to the DU driver, and none of the distributed RT-11 utilities
work on that last block, even with the /DEVICE qualifier.)
Did the version of 2.11BSD you're working from have disklabel support in
the hk driver? Disklabel support there was added recently (where "recent"
= 2 years ago).
The PDP-11 read the bootstrap in OK and the
bootstrap
was running but it was looping (I forgot the address).
Get us the address (HALT the 11/44, either with the front panel toggle
or control-P from the console) and we'll find out why it's looping.
