Some adverts and other Superbrain information:

Notice in this first advert that BASF disk drives are fitted, the full face of the drive is visible. Later models have Tandon drives and they are hidden behind the computer case. This first advert is from Practical Computing October 1979. First Advert Oct 1979 First Mention in PCW
It took until August 1980 for Personal Computer World to review the machine. By then it had lost the BASF drives. They reviewed a QD machine (Quad Density: 35 track, double sided drives). More up to date reviews at www.pcw.co.uk
