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.
