BA123 Cabinet with the cards in the following order (first in top, second
in bottom):
M8192 (Dual Height /73)
2Mb RAM (Dual Height)
2Mb RAM (Dual Height)
M8043 DLV11-J (Dual Height)
WQESD (Quad Height, Boot ROMs)
M9047 Grant Continuity / M7516 DELQA
M7546 TQK50 / M7555 RQDX3

Also in Cabinet is 1 TK50, 1 RX33, 3 150Mb ESDI drives.

There is one change in this configuration, and the one I've been trying to
boot with, I swapped the DEQNA for a DELQA. Somehow I don't expect that to
make the slightest bit of difference.

In any case I brought in the RL02, played swap the controllers and got
RT-11 installed on the one Hard Drive. Which means I was able to haul the
SMS-1000 I had running RT-11 out to the garage and free up a little space
in here.

While I'd like to get the floppy working, it's really my intention to use
the network to transfer files to and from the system.
