The schematic for the "7048" keyboard logic shows a PNP transistor controlling an output labeled "Clicker". It doesn't show what it is connected to, but I'm 99%

The schematic for the "7048" keyboard logic shows a PNP transistor controlling an output labeled "Clicker". It doesn't show what it is connected to, but I'm 99% sure it is a solenoid because there is a flyback diode protecting that transistor.
