[Coco] Coco Cartridge Prototyping Pak PCB

[Kip Koon]

Hi Bill and All!
I made some changes to the PCB, so I overwrote the files, so I imagine the links changed.  Sorry about that.  Use the links from my latest email.  Those should work.  Please let me know when you see them.  Thanks for letting me know.

Hi Kip,  I don’t know if it is just me, but the links you provide to dropbox give me error 404? something happening on my part? others seem to see it.
