The Texas Instruments’ Data Systems Group added two more 80386 based systems to its low-end Unix range on Friday. Joining the existing System 1300, introduced last May, is the 16MHz SP1000 and 1200 systems: the SP1000 is a desktop machine for up to 16 users, with interleaved memory expandable from 1Mb to 9Mb, and 48Mb or 87Mb disk options, priced from UKP6,600; the System 1200 is for eight to 24 users and has 8Kb cache, 2Mb RAM and 48Mb, 87Mb, and 140Mb disk options with prices starting from UKP11,600. The machines are priced at the same levels as the current 80286-based Series 1000 and 1100 systems, and use TI’s System V-compatible operating system based on Xenix 386 from the Santa Cruz Operation: the company says it will continue to offer the 286 systems for users not ready to move to full 32-bit architecture. Both are available immediately. Also announced was a new operating system, System V release 2.2, for the Motorola-based System 1500 multi-processor, which supports extended symmetric processing, and according to Texas eliminates the bottlenecks that occur under the systems master-slave architecture. Further additions to the top end of the range are also in the pipeline.
