No, Zane, it is made by Dilog. I heard that the device can do both tape and disk, but that to save money on DEC's royalty payments they only put the proms in for what you bought - which is not a problem since I got two of them!
I figure if you can't beat it, go with the flow! I am going to move the Plessey DCV54 to 160340 and let the SQ706 play at 172150, even though its diagnostic says its at 174500! The reason I know it is coming up at 172150 is that the DCV54 diagnostic says there is a non-DCV54 controller there, only when the SQ703(6) is plugged in. Unfortunately there are other jobs I have to do first, including fixing a very noisy power contactor in a DEC power controller that is upsetting the wife, and the microvax seems to have a ground loop voltage that is preventing me from entering anything on the console channel since I installed the power converter!
