Background

The power supply for the CPC464,664 or 6128 is not in the keyboard unit, it is in the monitor or an external television modulator.

Monitor models

  • The GT64 is the "Green Screen" monochrome monitor for the CPC464 and has the 5V power supply for the computer.
  • The GT65 is the "Green Screen" monochrome monitor for the CPC664 or CPC6128 and has the 5V power supply for the computer and 12V power supply for the disc drive.
  • The MM14 is the "Grey Scale" monochrome monitor for the CPC464+ and CPC6128+ and has the 5V power supply for the computer and disc drive.
  • The CTM640 is the colour monitor for the CPC464 and has the 5V power supply for the computer.
  • The CTM644 is the colour monitor for the CPC664 or CPC6128 and has the 5V power supply for the computer and 12V power supply for the disc drive.
  • The CM14 is the color monitor for the CPC464+ and CPC6128+ and has the 5V power supply for the computer and disc drive.

TV Modulator models

  • 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:
computer: 5V DC @ 1.7A
internal disc drive: 12V DC @ 0.4A
  • CPC6128:
computer: 5V DC @ 1.7A
internal disc drive: 12V DC @ 0.4A
  • 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 plug (note 2)
  • 2.1mm power line socket (note 3)
  • a power supply which can supply 5V DC and 12V DC (note 4)
  • 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 4)
  • wire

NOTES:

  1. The 2.5mm power line plug will connect into the CPC+ and provides the 5V power
  2. The 2.1mm power line plug will connect into the CPC and provides the 5V power
  3. The lead from the CPC664, CPC6128 will connect into the 2.1mm power line socket to provide the 12V power for the disc drive
  4. A PC power supply is ideal. If a PC power supply is used you will also require:
  • 4-pin (0.2") 5.08mm Spacing Polarised Power Connector (male) -- don't panic, this is the part fitting with the output from the power supply, see for example Molex connector or google image search. Other options are possible, use whatever fits the power supply you use, this one will fit virtually every PC power supply. Many PC hackers have some cables lying around, like power supply doubler cable, or old fan, with a suitable connector that can be reused.
Description Maplins Reference
2.5mm power line plug HH62S
2.1mm power line socket JK11M
PC power supply VL11M
4-pin 5.08mm Spacing Polarised Power Connector (male) JW64

Power to computer:

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.
