Changes
* 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 @ 2A
* CPC664: {can somebody help here please??}::computer: ?5V DC @ 1.7A:: internal disc drive: ? 12V DC @ 0.4A
* CPC6128:
::computer: 5V DC @ 1.7A
* 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:
* Outer diameter is 5.5mm for all plugs and sockets
* 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+.
What you will need:
CPC and CPC+:
* 2.5mm power line plug (note 1)
* 2.1mm power line socket plug (note 2)* 2.1mm power line socket (note 3)* a power supply which can supply 5V DC and 12V DC (note 34)
* fast acting fuse
* in-line fuse holder
* wire
CPC only:
* 2.1mm power line plug (note 2)
* 2.1mm power line socket (note 3)
* a power supply which can supply 5V DC and 12V DC (note 4)
* wire
CPC+ only:
* 2.5mm power line plug (note 1)
* a power supply which can supply 5V DC (note 34)
* wire

The plug has one outer and one inner contact. The outer contact is 0V, and the inner contact is 5V.
For the 12V of the CPC 664 and 6128 it is the other way around, the outer contact is 12V, and the inner contact is 0V.
