Scisys sold many chess computers in the UK under the marketing company name Acetronic. The Acetronic name was already well known in connection with video games. It made and marketed video games consoles which played games like Pong and Tank Battle from the late 1970s onwards. To the left is an Acetronic example, a Mini Chess packaged with a board and chess pieces called the Acetronic Electronic Chess. I have one of these and a similar one sold as the AudioSonic Pocket Chess.
