The Acetronic brand is short for Advanced Consumer Electronics Limited a company that was based in London, England.
Acetronic may have been owned or at the very least had a close connection to Radofin a video game console manufacturer out of London, England who sold the 1292 and 1392 Advanced Programmable Video Systems games consoles in 1979. It is believed that Radofin sold the same video game consoles under the name Acetronic called the MPU-1000.
These early chess computers were labeled and sold as Acetronic by SciSys, therefore it is possible that Radofin and Acetronic helped kickstart the ScySis business in United Kingdom around the 1979/1980 period. The connection certainly seemed to be there as Radofin was also manufacturing and selling Hong Kong made electronic calculators since 1974, The early SciSys chess computers indeed had the look and feel of a calculator.
Radofin went into liquidation in August, 1991.
