An intermittent contact on S22 would cause chaos as the computer would start executing code from a different ROM than what it was expecting to - perhaps even an empty ROM socket and it would make every other ROM in the system vanish. Perhaps the jumper and/or pins are corroded?I've just opened it up, pulled S22 out and back in (I've previously cleaned all the switches), as it's to do with the ROMs. I switched it on, and "BBC Computer 32K BASIC". Seriously? It's got nothing plugged in at the moment (like MMFS, joystick adapter, audio mod, new power adapter).
