In regards to retrofit kits for old Model 10s to upgrade them to Mark II functionality: I will be doing these but please realize I only ordered enough PCBs on this first lot to cover a single delivery phase as I needed to make sure the change was operative (we had mod'd two here, but experience has shown me this is not proof enough). I am placing a new PCB order in the next week and will place some extra mark II boards on that panel. Retrofitting consists of replacing the small board with the Mark II board and running a single component from it to a specific spot on the main board. Because of that. one solder joint will be required (it's nothing to worry about however, a very easy task). Expect the Mark II retrofit package to run about $25. No changes to the faceplate will be required.
