This schematic requires a TV with ''RGB input'' on Scart Connector (back in the 8bit era, many TVs have had only ''Composite input'' implemented on Scart connectors - nowadays RGB is also supported by DVD players and 3D gaming consoles, which is possibly increasing the chance to find RGB support on modern TVs).
The 9V and 1.5V batteries are optional. Instead of the batteries, you may also extract the voltages from elsewhere (like the CPC supply). They may be helpful to switch the TV to AV and RGB mode automatically, without needing to activate it via buttons on the remote control. Instead of Note that AV input can be usually selected using the batteriesremote control, you may also extract the voltages from elsewhere while manual RGB input selection is only available on more recent TVs. '''Battery duration''': since Pin 16 (like the CPC supplyRGB input selection)has an input impedance of 75 Ohm, valid are Pin8 it will drain a common fully charged 1.2V ~2500mAh AA battery in about one week, if left connected permanently to the TV set. {|class= "wikitable"|+| Pin| Voltage| Function| Note|-| Pin 8| 9.5V - 12V (| enables AV input| 9V is actually a bit too low), and Pin16 = |-| Pin 16| 1V - 3V.| enables RGB input||}
