1. A controller for a personal computer having a game board with a finite number of inputs for receiving and inputting to the computer a first limited number of analog input signals and a second limited number of discrete input signals, the controller comprising:

  • a number of analog output signal lines not exceeding said first number and a number of discrete output signal lines not exceeding said second number;

    a game board connector coupled to the analog and discrete output signal lines for inputting controller signals to the game board inputs;

    a plurality of switches all coupled to a common input voltage node; and

    circuit means coupling all of the plurality of switches to one of the analog output signal lines through a different resistance so as to produce a different discrete level of signal on said one analog output signal line uniquely corresponding to actuation of each of the switches;

    thereby enabling input of different controller signals from said plurality of switches to the computer through the game board connector by use of only said one analog signal line.
