I was coming to the same conclusion that
this could/should be considered an 11/73, since the KDJ11-B always seems
to referred to as the board in an 11/73. Totally likely that it was
upgraded in the "original" 11/23+ chassis some time in the past.<br>

I will pull out one of the cards for the laser cutter and get pics up
soon. Since I'll be in there, I'll take photos of the Zip interface card
as well.<br>

<br> Ah, gotcha. In DEC parlance, that's the "cabinet kit". What
probably happened is that it was originally an 11/23, and was upgraded
in-chassis to an 11/73, which uses a (slightly) different cabinet kit.

two
onboard SLUs which use the 10-pin connectors, not the 40-pins.

<br>Â There's virtually no chance of it being anything other than MSCP.
Several companies made Qbus SCSI host adapters; all of them (or nearly
so) implement MSCP.

<br> Not quite. 2.11BSD, the last release, is the first release to
require split I/D space. 2.10BSD and prior will run on the 11/23.
