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:

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.

Nice that you were able to get some basic signs of life from the
TDL-11. I don't think I tried a SCSI ZIP drive with the TDL-12, just a
standard hard drive and didn't have any issues that I can remember
getting that to work. The TDL-12 manual says it works with SCSI
addresses from 0-3. Does the SCSI ZIP drive (at least the external
one) only allow you to select SCSI address of 5 or 6, if I remember
correctly?
On the TDL-12 you can configure a single physical drive to appear as
up to four RL drives. I haven't looked at the TDL-11 firmware enough
to see if it should allow the same.
If you get it all working it is a useful setup to have around since it
allows you to run older OS versions which don't have native MSCP
controller support.
