Analogue Joystick Port (15 Pin SUB-D, female) (CPC Plus only)
The Analogue CPC+ Joystick port is somewhat similar to standard PC Joystick ports - with two important differences:
- 5V and GND are exchanged with each other, and,
- on CPC+ the buttons must be connected to a "select" line (instead of to GND).

- Two analogue joysticks could be connected by using an Y-cable. The Fire signals are the same as for the normal (digital) joystick port. Joystick 1 buttons should be connected to Pin 2,4,6, and joystick 2 buttons to Pin 10,12,14. Like the digital Joystick Y-cables the analog Y-cable should have diodes in the button lines.
- The A/D inputs have an input range of 0V (data = 00) to 2.5V (data = 3Fh), and an input impedance of 180k to Vcc.
- Not sure if the POTs on the CPCs analog X/Y inputs are to be wired to 5V or GND (or to both)? And, how they are wired on PCs accordingly?
