[Coco] Starting up memory problems and solution.

I've had mine come blank, but most of the time it's full of random
characters.  If it occurs with nothing in the slot, moving the 512k
board pins up & down in their sockets has cured it.  For the blank
screen, it's usually the cartridge slot's fault.  I think it's revenge
for not using it enough. :-)
