[Coco] [CoCo] Hello, newbie with new toy

I'm still not 100% convinced that the problem mightn't  be that the rompacks
aren't making good contact.  Does alcohol actually dissolve oxidation?  (My
chemistry is more than a bit rusty, but I doubt it.)

Did you clean both the upper and the lower sets of contacts?  (One surface
is typically harder to get to than the other.)  Try a pencil eraser on them.
