Hull-based Unix systems house Radius Plc has made what chairman Edward Sharp describes as it most significant acquisition to date, paying UKP1.2m for Computerised Business Systems Ltd of Cardiff. The acquisition is the Unlisted Securities Market counter’s third purchase in under a year. Last December, it paid a nominal fee for Advanced Business Technology Ltd (CI No 589), following up in October this year (CI No 782) with the purchase of the assets of Armstrong Micro Electronics Ltd for UKP500,000. CBSL specialises in computer syst ems for accountants and the legal profession. In the year to March 31, it made UKP80,000 pre-tax on sales of UKP2m. Increased profits have been warranted for the current year. Its entry into the fold increases Radius’ Unix capability still further. At the time of its public flotation in October 1985 (CI No 288), Radius did 65% of its business with Texas Instruments’ kit running under TI’s proprietary operating systems. CBSL’s main product, the Profasy system for accountants, has over 300 installations, a total Sharp says is impressive considering that it has only been sold from a single base in Cadiff. Profasy will in future be sold through all of Radius’s nine offices. Radius also plans to sell some of its existing products from Cardiff, its first outlet in Wales and the West. The UKP1.2m price for the 70 employee company is made up of UKP120,000 in cash with the rest in shares. Computerised Business owner and managing director Ian Munro will be joining the Radius board.
