[Coco] Multi Pack Replacement

[Juan Castro]

I'm visualizing something that looks like 3 CoCo cartridges put
top-to-bottom, with the slots looking up. And a 5-6 in flat cable to
connect it to the CoCo cartridge slot. Could have two dip switches for the
slot selection. Pro: it wouldn't fry your CoCo when the resident toddler
comes running from nowhere and bumps into it.
