I got this on eBay, the Seller is from Dallas, TX and stated in the Auction that this Unit was Surplus came from a Tandy Outlet Store in Fort Worth, TX.

 

I know this Unit won't work without 12VDC, so I had previously bought some Fujitsu MB8877A LSI Chips, in case I got a 26-3022 Board. Luckily the Western Digital FD1793B-02 is socketed, so a Simple Chip Swap is all that is needed to Upgrade this Controller.

 

When connected to the CoCo2, the Boot Message stated, "Disk Extended Color Basic 1.1", on the CoCo 3 the Boot Message stated, "Disk Extended Color Basic 2.1".

 

This is a Picture with the WD FD1793B-02 chip still installed.
