bought this on eBay suspecting it was LSI-11 based because of the floppies labeled DY:
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.
