Hi, Richard.

RL>        I'm after a routine, bios calls or hints on how to
RL>output DAC signals using a joystick port.  I already have a
RL>C++ routine for ADC using interupt calls, (let me know if
RL>anyone want's it to read joystick values and I'll upload it
RL>to 500cc) but I need one to output as well.
RL>.
RL>        Any help on how to do it or if it is imposible, would be appreciated

Not possible, unfortunately. The joystick interface is simply 4 timers
which are set by an OUT instruction from the PC, then run down at a
rate determined by the resistances of the joystick potentiometers and
some internal capacitors & resistors (.01uF/2.2k). The PC detects when
they cross the lower threshhold voltage of the timer chip.
