available: Q-bus SCSI controller

I have a Distributed Logic Corp, SQ716A Rev J, differential (high voltage) Q-Bus SCSI disk controller that I'm willing to part with. I've tested it by booting into it's internal monitor on a uVAX (and that works), but I don't have a differential SCSI disk to test it with, so I guess it's as-is. Things I'd be willing to trade for (all or part). 1.) One each, RL02 unit select plugs 2 and 3. 2.) DEC BA123 cabinet kit for a RLV21 (RL01/RL02) disk controller. 3.) Rear rack mounting brackets for a DEC BA23 (5.25 inch rack mount uVaxII chassis). I have the two long side rails, but there is a small bracket which attaches each side rail to the rear mounting bracket in the rack cabinet. 4.) Some number of RL02 packs. Let me know if you are interested... Bill
