[Coco] Coco Cartridge Prototyping Pak PCB

[Kip Koon]

Hi Guys!
Here is the second version of the Coco Cartridge Prototyping Pak with all
your suggestions.  How did I do Ed?  Not only have I included the links to
the renderings from OSHPark, but I have also included the Schematic and PCB
layout in PDF form since so many people are expressing an interest in this
project and have made suggestions.
The following links are the top and bottom renderings of the PCB from
OSHPark.

Here are the links to the schematics and the PCB layout.  The first
schematic has all the decode logic.  All the second schematic has are the
holes.  The third link of course is the PCB layout from Eagle Pro. V6.4.0.

Thank you Ed for offering to help.  It was late when I got back on, so I
went ahead and tried my hand at some clean up.  
If I missed someone's suggestion.  It was not intentional.  Please continue
to inspect my work and let me know what you think?  I appreciate all your
suggestions.  It helps me to make a better PCB.  Thanks a bunch!  Have Fun
Guys!

OK <ignorance switch on>

I am not sure what the silk screening critiques are about. IS that referring
to the printing over some of the holes? To my untrained eyes, it looks good.
TIA
