/* Analog PC Joysticks */
Analog PC Joysticks have a very similar 15pin connector. Theoretically, a few PC joysticks might be CPC+ compatible. However, in practice, this is rather unlikely - the potentiometers must have correct value, the button common pin must be correct, and the joystick may not contain additional electronics like auto-fire circuits, electrolyte capacitors, or digital-switch to analog-signal converters.
* '''Caution''' - compared with PCs, the '''CPC+/GX4000 do output reversed polarity''' reversed polarity on the joysticks power supply ''' pins, so any special electronics in '''PC joysticks may get destroyed''' when connecting them to a CPC Plus/GX4000.'''
If you want to use a PC joystick: Remove any electronics other than the potentiometers and buttons. Ensure that buttons are wired to correct common pin. And, probably you'd need to replace the potentiometers (if they aren't 180K) - however, this may be the complicated part: potentiometers in analog joysticks aren't necessarily matiching standard mechanic dimensions.
