bought this on eBay suspecting it was LSI-11 based because of the floppies labeled DY:
https://www.ebay.com/itm//192437124163 It's kinda neat, has a very late (1989) AED WINC-05 disk controller in it, 11/73 and a bunch of custom daq boards. It also has a Dilog Qbus to Unibus converter (didn't even know they made one) and it appears all the custom boards are on the Unibus. I doubt I'll ever find docs for it though.
