Acorn Computers Plc launched into the Unix world in January 1989 with the low-cost – UKP3,500, since reduced to UKP3,000 – R140 workstation, and during that time has found its niches, despite fierce competition from the big Americans. At last week’s Unix User Show it unveiled its second generation product, the R200, using the ARM 3 RISC processor, which it says is be priced to re-affirm Acorn’s position as a supplier of affordable workstations – the company is obviously aware of Sun’s new SLC Sparcstation, priced at around UKP4,000. Acorn, which recently announced increased year-end profits, hopes the new machines will increase its market share in health care, university and polytechnic applications, as well as specialist technical markets such as image processing and computer-based training. It’s on 12 weeks’ delivery.
