NOTES:
* Outer diameter (A) is 5.5mm for all plugs and sockets, inner diameter (B) is 2.1mm for classic CPCs and 2.5mm for Plus * short and long plugs exist, the ones used for the CPC and Plus are the short ones with approx. 9.5mm (vs. 14mm for the long onesC)
* for 5V plugs and sockets, the inner contact is + and the outer contact is GND
* for 12V plugs and sockets, it's the other way around, the outer contact is + and the inner contact is GND
There are ATX breakout boards available on e.g. Ebay or Amazon, which will add fuses to the 12V and 5V lanes of the power supply, so they can be safely used with the CPC and Plus.
