I don't have anything for the DEQNA, but the cable info I've seen for DELQA has the comment "this one would probably work for a DEQNA, too." The document I grabbed from http://antinode.info/dec/delqa_cable.html says: 29 December 1996. SMS. DELQA (DEQNA?) Ethernet Cabinet Kit Cable This document describes the cabinet kit for a DELQA Q-bus Ethernet interface board. The kit comprises the AUI connector and fuse assembly at the bulkhead panel, and the cable from the bulkhead panel to the DELQA board. The kit for a DEQNA was similar, and this one would probably work for a DEQNA, too. The connector at the board end of the cable is a 2x12 position, 0.1-inch pitch female. The corresponding connector on the DELQA (M7516[YM]) is a 2x10 male. The outer two pairs of hole on the female connector are unused, but the male connector accomodates the 2x12 female connector. The pin numbers shown below are for the 2x10-pin male connector on the board. The AUI connector is a DB15-S (female). The fuse on the bulkhead panel near the AUI connector is a 1.5A, 25V, slow-blow.

"Bare" is the inner shield. The outer shield is connected to the bulkhead panel near the AUI connector. As the author (dimly) recalls, the DEQNA cabinet kit cable had one fewer wire, presumably not a very important one.

I think I have a DELQA cab kit left and maybe I can take a photo tomorrow. I'll look for a DEQNA one too, but they may all be long gone now. (I also looked at the DEQNA UG but I couldn't find wiring details in there ... but it was a very quick look). Antonio
