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.
