Until 1976 Sinclair Radionics had enjoyed 15 years of strong turnover and profit growth. However, the company sustained losses related to difficulties with chip supplies for the Black Watch. As a result there were insufficient internal funds available for the final stages of the pocket TV project Sinclair had been working on for some 10 years. In August 1976 the National Enterprise Board (NEB) provided £650,000 in return for 43 per cent stake in Sinclair Radionics. Sinclair did not like sharing control of his company. Thus, he converted a company he had purchased in 1973, Ablesdeal Ltd, into Westminster Mail Order Ltd, which was itself renamed to Sinclair Instrument Ltd. In this way, he maintained control of his most important projects.
