I might have been in the audience for that talk... >> DEC RKV11D Q-Bus controller for RK05 disks (on my LSI-11/73 system) >> Originally, it only supported 16-bit addressing, but I added the >> chip and wires to make it support 18-bit addressing.

I have an RKV11D that I've used under RT-11 with 16-bit memory... love to put it on a larger machine. Good luck on posting your stuff. I'm far away so I'm not likely to be interested in anything huge and heavy, but I'll take a peek. Cheers, -ethan
