[Coco] Source for Coco/Arduino interface

[Matthew D Stock]

Hi all,

This is still a work in progress, but I put together with the code and 
schematics for the bus interface board I'm building.  I'm in the process 
of doing a redesign to reduce the part count and make it a little more 
like a general "experimenter's board," but this version will work well 
for people who want to just do ROM programming (like in the video).

Repo is at https://github.com/mattstock/cococpld

I expect I'll have populated boards available for sale at some point 
soon, but I thought a few people might want to look at the code in the 
meantime.  Let me know if I missed anything - I reorganized stuff on my 
end to get this release together.

Also, I just finished putting together a simple card-edge transceiver 
breakout board that has a pinout compatible with the Terasic DE1 FPGA 
board.  You should be able to plug this board into your Coco and use a 
ribbon cable to plug into your FPGA or breadboard.  Email me at 
stock at bexkat.com if you're interested and I'll figure out the cost.

More videos soon.
