[Coco] Mystery "FDC (EAGLE FORMAT)" Schematic on MaltedMedia FTP

[Chad H]

Yikes!   Hearing that more and more when stumbling across old projects and the creators have disappeared due to a falling out.

>From comparing the board view, yep that's definitely the same board.  Was a version of Disk Basic ever made?  I'm guessing NitrOS9 compatibility is out of the question.

That may be the CoCo FD/HD controller designed by Chuck Youse in 2008. He sent me one of the prototypes so that I could make a version of Disk Basic that would work with it. The 8207AA controller is nothing like the Western Digital chips used in other CoCo floppy controllers.

After Chuck got involved in a flame war on this list he decided to abandon all his CoCo projects and leave the community.

I have posted a picture of the prototype here:
