Internals
Motherboard
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.
Power Supply
Electron is powered at 19V AC. It is possible to get cheap replacement power supplies, that are used today for various telecommunication equipment.

Would like permission to use photo of the Acorn Electron on an article I am writing about the Acorn line of computers.
Ok, no problem. Please post a link to the article once it is ready. Thanks!
Hi there! You seem to be a crack in electronics and also used to the electron harware, too: Im wondering, why my electron, I live in belgium but had to buy a computer in the UK, has got a power supply that is 12V/1A. It may be the original, it is brandet “acorn”. Now the plug does not fit into the continental european 230V net, so should I replace it with 12V? Or 18V? Both there, but im not interestred in destroing it… So a hint/clue would be nice. tanks a lot – Anne
@ The Schmitts – The original PSU was 19V AC, and was a very heavy old-fashioned transformer. It is immediately rectified into DC, then regulated down to 5V by the internal PSU board. A model 12V DC switching power supply will work just fine. You will almost certainly have one already as they are very common. The polarity does not matter.
