Drat, it doesn't seem to work. Here's the
procedure I tried:
1. Halt the CPU and enter ODT
2. 17774400/000201 400
3. Set halt button back to Run
4. Examine 1000 and up... nothing there but 000000's and 177777's
No, actually it DOES work. As is often the case in these situations,
the failure was human error. I miscounted my QBUS slots and had this
in the A&B slots of row 5 of the backplane, with nothing in C&D -- no
DMA grant continuity! I switched it to C&D of row 5, and now it works:

@ 1000g
IAX 3.2 (C) 1984 TD Systems
B Boot
C Configuration
D Display
E Exercise
F Format
S SCSI Cmd
T Test TDL
W Write BSF
DMON=
Now getting it to talk to my SCSI ZIP disk will be another exercise
entirely. So far it's not working, but I anticipate human error there
as well.
