Electron is powered at 18V AC. It is possible to get cheap replacement power supplies, that are used today for various telecommunication equipment.
Electron has three video connectors: RF, composite and RGB.
Composite video output by default is monochrome only. It is very easy to enable colors on this output – all that is needed is to find and close LK4 link.
