The fact that the board have four edge connectors and not six totally
excludes PDP-11.
The first and last picture of the ebay listing above clearly has SIX edge
connectors.
And, in fact, a number of PDP-11 peripheral boards had only 4 connectors.
CPU boards and memory did usually have 6.

I based my PDP8 on googling and looking for comments about the processor
type.
There was a history page which said they used PDP8s in their
designs. I know that the 6 up is more common for PDP11, but wanted to
throw it out there. I figured a core board of the right variety for $195
might be a steal since the seller didn't list it to be on the DEC hardware
searches on Ebay.
Thanks for Al's comment on the 6800 board. I see about half of all photos
being crap these days on ebay. I was crossing fingers it would be a design
that started out as an actual dec, and maybe had a small board built up
with a Harris pdp processor on it. I know that is a really long shot, but
not impossible.
thanks for the comments.
