In the early 1970s a socket to hold multiple DIP chips was being sold under the brand name DipStik. Up to six chips were inserted in a trough in the socket, a top screwed on with thumbscrews on the ends. It had solder lugs on the top and bottom for each of the chip pins. We are restoring an old

PDP-11 LDA BFD backend for gnu binutils
