The boards in question were standard DEC M-series,
with vanilla TTL parts. No gold plating except the
edge connector, and whatever was used inside the
plastic DIPs.
Older plastic DIPs? Guess what...
Even with modern SOICs, there are a few bucks per pound in vanilla.
CERDIPs? More than a few bucks per pound.
He paid $50 a board for a few quad or
hex-width boards.
That is quite high - more than scrap. Who knows.
I really couldn't tell you what the gold is worth,
but
I have a good idea how much I have to offer for
certain kinds of boards to pry them away from someone
who does.
It is very good to know what you are up against.
