On the interface board, it's connected to the collector of a transistor, pulled up to Vcc by a 1k resistor, emiter to ground, base goes to the on-switch (via 1k resistor). It doesn't connect to the MAS or anywhere else if I didn't miss anything. Too bad I forgot that we have beautiful schematics on the rockbox site, that would have saved me a complete disassembly of my jukebox...
