Thanks for the brochure.
That looks like a fascinating project!
Computerworld mentioned it occasionally in 1980.
I love that "Pl/1 will soon emerge as the dominant language of
microcomputers"
If you haven't already exhausted such leads (apologies if you already
have), some trivial GOOGLE'ing turned up the name (and autobiography) of a
guy who designed one of their disk controllers:

Sorry, NO technical details of the controller that he designed.

Well. Now this is NOT a standard 179x that has written
this. As I mentioned
early on in this thread it was not at all possible to read the disks with a
standard controller. The bit rate was off by quite a bit and the general
format is different. So this is not necessarily a CRC at all. The machine
that has written these is the Q1 Lite computer. A very odd mid-seventies
system. http://bitsavers.trailing-edge.com/pdf/q1/Q1_Sales_Brochure.pdf.
