Mystery Q-bus boards

Poking around the web, checking bitsavers. org and Manx, and looking at the Q-bus field guide have so far turned up nothing for me. I'd like to ask all of you Q-bus experts for some input. I've cobbled together a webpage with some images here: http://www.rogerwilco.org/mystery_boards At this moment, I'm most interested in information and documentation on the Clearpoint Q-BUS 11B. I'd like to use this in a PDP-11/23+ or 11/73, hoping to get Ultrix-11 or BSD2.9 running. All comments are welcome on- or off-list. Thanks! J ----- The first board has 6 FPGA's on it, that is what those AT&T chips are... http://www.datasheets.org.uk/search.php?q=ATT3020-70M68&sType=part you can get some specs and datasheets there. My guess is that you will only really be able to figure out what that board does by disassembling the ROM... the second one is interesting, it has a 6809 processor, a 2Mhz programmable timer and 8 2Kx8 Srams the SMS card, I'm not certain about, I know that SMS made several models of hard disk controllers, the one I have had the most experience was the OMTI controller series, the ones I worked with used an external chassis and a custom board in the computer (or in the case of the later tandy computers (model 3 or 4) worked connected to the expansion bus with a ribbon cable The clearpoint Qram11b, I did a google search and found several companies selling them, you may be able to get docs on the card form one of them if no one on the list has any.
