Now that I'm getting used my Model M mini, I've discovered something quite interesting: jamming the left Shift key down really hard inserts a ">" character. Does this mean every Model M membrane is really an ISO membrane, and the US layout just arranges the keycaps differently? If so, this opens up an opportunity to make an "ISO" space saver using a couple replacement keycaps, an extra buckling spring, an extra spring column, and some blood and sweat.
Anyone else notice this behavior (Full-sized M or not)?
