[Coco] make-do ROM Paks

[Mark Marlette]

Depending on what the final use is for this device. I HIGHLY recommend  
that that the card edge connectors are gold plated.

Generally a ROM pak wasn't because it would be inserted and removed  
often, thus cleaning/wiping would occur before it could/would tarnish.

If one was going to make a pak that would stay plugged in for a long  
time. You WILL have problems. That is why all of our devices have the  
gold plated edge connectors. We have seen it in our proto-types. I  
don't gold those, but still use them in the labs.

Not all PCB houses will have the gold etch process. The good ones will.
