Acorn Computers Plc points out that all the support parts announced for the Acorn RISC Machine by VLSI Technology (CI No 650) were designed by Acorn (pity Acorn didn’t tell us about them instead of leaving VLSI to make the announcement), and that although the present practical real memory limit of the ARM is 4Mb, the part can address up to 64Mb of real memory; Acorn also says that the board-level system for the IBM XT or AT is an evaluation rather than development system.
