Harris offers Unix-based engineering workstations for software developmentTwo new Unix-based workstations, in-

troduced by the Computer Systems Divi-sion of Harris Corporation, can be usedas either stand-alone workstations or aspart of a Harris workstation and super-minicomputer network.The new 32-bit Harris Station 10 and

Harris Station 20 are designed to bringhigh-performance multitasking com-puting power to individual users. High-resolution graphics and a wide range ofsoftware packages make them ideal forcomputer-aided engineering and soft-ware development, according to Harris.Both the HS-10 and HS-20 can be

linked to the company's super-minicom-puters via RS-232 serial lines or throughEthernet local-area neworking. Accord-ing to Harris, this capability enables itsmore powerful super-minicomputers tooperate as compute servers, offloadingcomputationally intensive tasks from theworkstations, or as file servers, storingand quickly accessing large files anddatabases.The HS-10 and HS-20 achieve .575-

MIPS performance, as measued by theWhetstone benchmark. Multiple VLSImicroprocessors and a dual-bus archi-tecture distribute the processing load toappropriate subsystems. The work-stations operate in four modes: as stand-alone computers, fully integrated graph-ics systems, Ethernet network nodes, orRS-232 terminals for Harris super-mini-computers.The CPU in each workstation uses

dual 32-bit microprocessors-a 68010and 68000 running at 10 MHz. Multi-tasking is enhanced by the availability of24 sets of 32 double-precision registers.The dual-bus architecture enables work-station system modules to communicatevia the 8M-byte/second system bus,while the peripherals connect through anenhanced 6M-byte/second Multibus.

Harris workstations achieve a signifi-cantly higher level of performance in sci-entific applications with the floating-point processor and array processor. Theoptional floating-point processor oper-ates in parallel with the CPU, handlingsingle- and double-precision floating-point calculations. It typically performssingle-precision add or multiply in 1.66ss.

All computations using the floating-point processor are carried out to the fullaccuracy specified by IEEE standards,Harris states. Commonly used transcen-

dental functions such as sine, cosine, andtangent are supported in hardware.The workstations are menu-driven to

handle a range of applications, and soft-ware packages are available for en-gineering, computer-aided design, draft-ing, graphics, and administration. Ap-plication support libraries are callablefrom C, Fortran 77, and Pascal.The Unix operating system in Harris

workstations is compatible with AT&TUnix System V, enhanced with real-timeand Berkeley extensions. Other Unix-based software products available fromthird parties include packages for com-puter-aided design, general engineeringand science, graphics, database manage-ment, and remote job entry.According to Harris, the Unix-based

workstations provide an outstanding en-vironment for software development. IfUnix practices for generating portablesoftware are followed, the software de-

veloped will execute on other computersystems running Unix.Packaged as a stand-alone unit, the

basic workstation includes a 32-bit CPUwith three RS-232 lines, IM byte ofmem-ory, an independent graphics processor,a 50M-byte disk drive and 45M-byte car-tridge tape drive, the Unix operatingsystem with Fortran 77 and C languages,a 19-inch monitor, and an eight-slotchassis in pedestal packaging. The stan-dard HS-10 includes a monochromegraphics subsystem with a 19-inch 1024x 800 monitor. The HS-20 features col-or graphics capability with a 19-inch 832x 600 monitor.Prices for the HS-10 start at $32,500;

prices for the HS-20 start at $39,900.For additional information, contact

New workstations extend the Harris line of computer systems to the single-user level.Support for Ethernet local-area networking links the new HS-10 and HS-20 work-stations, as well as linking them to all Harris super-minicomputers. These networksfeature program-to-program communication, remote file transfer, virtual terminal,network print spooler, and electronic mail facilities. Harris super-minicomputers canoperate as compute servers or file servers for the workstations, off-loading large tasksfor quicker response.
