The launch of Siemens Nixdorf Informationssysteme AG’s new multiprocessor computer line has been delayed. Topix Abteilungsrechner & Workstations reports that an announcement regarding the B20, on which Siemens Nixdorf has been pinning so many hopes, was planned originally for the autumn. It now seems set to be pushed back at least three months, as the chosen central processing units are causing problems. It therefore seems possible that the B20 will be equipped directly with Intel Corp’s P5 chip rather than upgradable 80486 CPUs. However, work on the MIPS Computer Systems Inc R-series RISC-based B20 line is going ahead somewhat quicker, with a launch expected by the start of 1993. The multiprocessor version of the R4000 central processing unit is expected, finally, in November. Even MIPS owner Silicon Graphics Inc is said to want to speed up its multi-processor work by using the P5 chip.
