I just ran across a sale on epay by a guy who thought you could pull the 
processor chip off the board and sell each in separate auctions.

I couldn't find the processor from the huge number of gold scrap chip 
auctions he had, but he said it (or the other) chip(s) for the board 
were listed.

I think giving him the benefit of the doubt, he thought that the two 
were separable like motherboards and processors are now day.  Worst case 
he was just an unfortunate idiot that destroyed the board.

I sent him an email telling him the value I place on it (tested) and 
suggested that he think of older boards as the full components to be 
kept together unless he wants to destroy the board, or knows what he is 
doing breaking them up.  Of course on old Qbus and the like boards, one 
does have some components that are more valuable if you break up the 
board, and pull "unobtainium" chips.  But pulling out the KDF processor 
isn't one of them in general.

I just bought a KDJ Jaws chip for a "round 2it" project to try to get it 
running, as I archived a PDP11 "Hack" page indicating how to get one 
running on a proto board with minimal hardware.

I don't know if you could do that with the KDF, but that isn't what this 
guy is doing.
