[Coco] Multipak redesign/replacement / New CoCo...

[Zippster]

And in the spirit of keeping it simple, the project Louis referenced below
is a basic multipack.  The design looks ready to go with LS logic.
If the logic is put in a CPLD, tweaks to the circuit can be made through
programming if necessary later.

It would also make it considerably smaller.
