* 5V and GND are exchanged with each other, and,
* on CPC+ the buttons must be connected to a "select" line (instead of to GND).
* The ADC hardware in the CPC works only with 180K ohm 180kΩ potentiometers (unlike the software counters in PCs, which works with different types, in range 10K...300K ohm300kΩ, or so)
'''Caution''' - there is no resistor in the supply lines - the 5V/GND pins connect directly to the computers '''2.4 Ampere''' power supply - so, there's a good chance that the CPCs reversed polarity will '''destroy''' any electronics (electrolyte capacitors, auto-fire circuits, etc) in connected PC joysticks.
* 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 (there are no diodes between pins 7+14 and 2+10 the mainboard).
* The A/D inputs have an input range of 0V (data = 00) to 2.5V (data = 3Fh), and an input impedance of 180k 180kΩ to VccV<sub>cc</sub>.
