Sigh. So little time, so many keyboards. The Mark XIV keyboard, using surface-mount pushbuttons was utter fail. Had I actually looked at them, I would have seen that they can't withstand any sideways force at all. Consequently, they break when you look at them sideways. I only discovered this after arriving in India and finding three switches completely useless. Oh well, back to the reliable Marquardt switches. Will remove the surface mount switches and replace them with the Marquardt switches.
