Memory Computer Plc, the Dublin systems house quoted on the Unlisted Securities Market showed a 57% increase in turnover in its first half results released yesterday. There was a 73% growth in the UK market which now accounts for almost half of Memory’s total business. David Stern, corporate development manager, said the company’s increased expansion into Unix-based software in the last six months was a major factor for the increase in sales. He expects the investment in Unix systems to yield substantial results in the near and medium-term future. The company underwent a recent reorganisation of operations, including investment in personnel, training plus upgrading the group’s internal computer systems which was reflected in the small increase in pre-tax profit to UKPIr104,000 from UKP86,000. The company has also invested in the development of Prime-based software packages which should result in a series of new products in the new year. Following the demise of Memory’s 74S281 4-bit bit-slice M55 machine the company has now completed the transition from computer manufacturer and distributor to a value added systems, software and maintenance company. Memory is also trying to de-emphasise its hardware distribution role.
