 Let me first describe the apple buttons on the //e.
 The Open-Apple symbol on the //e is the same as closing SW0,
 and Closed-Apple is the same as closing SW1.  There is no key for SW3.
 
 Sw#'s refer to the "game port" switch connections,and are sometimes
 referred to as PB0-PB2, for pushbuttons. 
 
 On the //e these signals are available on both the 16 pin internal
 game I/O port, as well as the 9 pin D-connector on back.  On the
 earlier Apples (][, ][+), there is only the internal game port. 
 My joystick has two pushbuttons corresponding to SW0 and SW1.
 I PRESUME THAT USING THESE SWITCHES WILL LET YOUR SOFTWARE WORK,
 ASSUMING THAT IT CAN RUN WITH THE FIRMWARE OF THE EARLIER APPLES.
 
 To use the internal port then, either get a joystick, or make your own
 switches.  Per the Apple manual, each switch input needs a 560 ohm pull-down
 resistor from the SW pin to ground, with a momementary-contact normally-open 
 switch from the SW pin to +5V.  All are available on the connector.
