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.
I have the DZ11 (M7814) user's guide right here.
1) Priority insert level 5 goes in E41.
2) E72 -- Address.
Closed (on) is binary 1.
A12 A11 A10 A9 A8 A7 A6 A5 A4 A3
-----------------------------------------
| 10| 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
on | | | | | | | | | | |
| | | | | | | | | | |
off | | | | | | | | | | |
-----------------------------------------
Addressing examples:
160000 -- A12 thru A3 OFF
160010 -- A12 thru A4 OFF, A3 ON
177770 -- A12 thru A3 ON
(OFF=Logical 0, ON=Logical 1)
3) E81 -- Vector
Closed (on) is a binary 0.
-unused- V3 V4 V5 V6 V7 V8
---------------------------------
| 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
on | | | | | | | | |
| | | | | | | | |
off | | | | | | | | |
---------------------------------
Vectoring examples:
Vector V8 V7 V6 V5 V4 V3
300 ON OFF OFF ON ON ON
310 ON OFF OFF ON ON OFF
770 OFF OFF OFF OFF OFF OFF
(ON=Logical 0, OFF=Logical 1)
Let me know if you need any more info.
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).
Did you successfully build from a boot-tape image on the emulator, or did you copy
the RP06 image (such as on the PUPS archive) directly to the disk and tranfer
the physical drive to the PDP? (And what method/command did you use?)
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.)
I do this regularly for my vaxen. 10 to 1 Steven Schultz has been this route
on the PDP-11's tho (Hi Steven :).
Lemme know if I can help more.
Regards,

Hmm.. I've got a manual for the Viking UDT, and I'll try to remember to
bring it in on Monday.
I don't know anything about how 2.11BSD boots. However, I had an
interesting
time trying to get 4.3BSD on my 750 to boot off this controller. It
turned out
that the Viking's emulation of the UDA50 isn't *quite* accurate, and
that the 4.3 boot
code was using one of the edge-of-the-envelope features that the Viking
didn't quite
emulate right. I modified the bootstrap slightly and got it going.
Whether this
has anything to do with your problem, I don't know. (It was worth all
the effort
in the end, to see the monster hulking 750 booting of a little dinky
plastic zip drive!)

[Replied to Tim but not the list - oops!]
Method to transfer drive: FTPd disk image to MicroVAX running NetBSD,
used cat. Saved the RT11 image beforehand. When BSD died I put RT11 back.
RT11 works.
Disk image was an RP06 constructed from a boot tape I made. It used stuff
from the PUPS archive but wasn't the image from the archive.
I will get the loop address shortly - I have to get an extension cord back to
power the machine.
