The first official yellowcog PCBs are now being played with and seem to work. One or two problems have been found but can be "fixed" with software. One strange non-terminal manufacturing problem also found where the physical board doesn't match the gerbers.
The first official yellowcog PCBs are now being manufactured. We finally plumped for using EAGLE (although not the free version). Thanks to my (now ex) colleagues who helped out by double-checking the schematics and layout.
