[Coco] Problem w/MultiPak and Coco 3

[David Gettle]

You may also try track cleaner for model trains, that is what I've been
using to clean the edge contacts on my CoCo system for several years with a
cotton swab or clean cloth (cartridge side). For the actual card edge plug
I've been using a piece of computer circuit board with cloth glued to it
and soaking the cloth with track cleaner. You can still get the correct
thickness circuit board from RadioShack.
