[Coco] Electronic Computer Festival Badge Idea

[Dave Philipsen]

Sounds like a good deal.

I have seen some designs use a machine pin socket for a DIP chip and
actually surface mount much smaller chips inside the confines of the
machine pin socket on the same side of the board in addition to perhaps
an SMD or two on the other side of the board...
