Electron has three video connectors: RF, composite and RGB.
Composite video output by default is monochrome only. It is very easy to enable colours on this output – all that is needed is to find and close LK4 link.
RGB output has the following pinout and can be connected to SCART TV input.
Electron is powered at 19V AC. It is possible to get cheap replacement power supplies, that are used today for various telecommunication equipment.
