Prior to flotation in the UK later this year, McDonnell Douglas Information Systems has enhanced its Series 19 range to offer co-resident Unix and Reality OS Pick application support at the high end, and four new Series 19 models at the low end. The RX series of multi and parallel processors are based on Encore Computer Corp’s Multimax machines, and applications and tools from the Reality operating system will run alongside Encore’s Unix. The two companies signed a joint development agreement in October last year (CI No 1,292), after a similar agreement with Unidata Inc, Denver to develop Reality implementations of Pick running under Unix failed to bear fruit (CI No 1,073). The three models in the RX range have Reality database characteristics integrated into the native Unix, and are totally compatible with the rest of the Series 19 range. The RX22, rated at 34 MIPS, comes with four to eight processors, 64Mb and 1.2Gb or 192Mb and 7.2Mb respectively. The mid-range RX44 has between eight and 12 processors. The eight processor model runs at 68 MIPS with 128Mb and 2.4Gb, and the 12 processor has 320Mb and 9.6Gb with 102MIPS. The top-end RX66 has 12 processors, expandable to 18.
