* MP-1 is the television modulator for the CPC464 and has the 5V power supply for the computer
* MP-2 is the television modulator for the CPC664 and CPC6128 and has the 5V power supply for the computer and 12V power supply for the disc drive.
== Power requirements ==
The power requirements are (information taken from the underneath of the keyboard unit from real machines):
* CPC464+: computer and internal cassette player: 5V DC @ 2.4A
* CPC6128+: computer and internal disc drive: 5V DC @ 2.4A
== Power connectors ==
To connect a power supply to CPC you need the following connectors:
* CPC classic:
* 2.1mm power line plug (providing the 5V for the CPC)
* 2.1mm power line socket (providing the 12V for the floppy)
* CPC+:
* 2.5mm power line plug (providing the 5V for CPC and floppy)
NOTES:
* All voltages MUST be smooth, the CPC does not have a internal regulator!
* If you want to use the computer without the monitor, then you will need to build a television modulator, or a lead to connect to a television with a SCART input.
== Power pack project ==
This project describes a method to make a power pack for the CPC and CPC+.
