TV SCART cable

A TV SCART cable allows to connect the CPC/CPCplus to the TV set. This is especially helpful if you couldn't get your hands on a colour monitor or want to use the CPC/CPCplus as a video console in the living room.

Schematics

Amstrad/Schneider CPC (classic)

Colour Picture (RGB)

This schematic requires a TV with RGB input on Scart Connector (many TVs have only Composite input implemented on Scart connectors).

The 9V and 1.5V batteries are optional. They may be helpful to switch the TV to RGB mode automatically, without needing to activate it via buttons on the remote control.

Black & White Monochrome Picture

This schematic passes Luminance to the TVs Composite Input. It's giving only a monochrome picture, the advantage is that it works on nearly all TVs including such without RGB input.

Doing this would be useful only for using the TV as replacement for the GT64/GT65 monitor.

Alternative RGB Wiring

Amstrad CPCplus (In theory also GX4000, but it has its own SCART outlet)

Additional Resistors

Info from OCT: "I recall that when Amstrad Action came up with the proposal for a SCART cable back in issue AA41, numerous readers wrote in suggesting that resistors (most commonly: slightly below 330 ohms) should be connected "in series to the colour signals [...] for improving picture quality" (AA45, June 1989, FORUM, p. 23), so they seem to have appeared overblown in comparison to the CTM644s' back in the day."
