CAD system operates without interface to host computer

Aydin has announced a new product for the computer-aided design systems industry. Aycad, an interactive graphics workstation with a computer system packaged internally, is configured with three Intel microcomputers, two high-speed math coprocessors, and a bipolar bit-slice computer dedicated to a single user. The result is a stand-alone graphics system designed to perform total applications in architecture, 3-D mechanical design, and manufacturing without having to interface with a host computer.

The components of the Aycad system are an Aydin 5216 display computer, a high-resolution (IK x 1K) color monitor, a function keyboard, a station console, a 36~ x 48 ~ digitizer with 3-D coordinate display, and multiple 35M- byte Winchester disks with 8-inch floppy disk backup. Interfaces to video hard-cop, units and all major plotters are available. Prices start at $75,000 per Aycad workstation

System 80 models offer 4.8G bytes of disk storage

Sperry Univac has added Model 4 and Model 6 to its System 80 family of computers. The models offer a disk storage capacity of up to 4.8G bytes, a disk drive capacity of 16, a disk- caching feature that reduces the number of "read" operations performed on the disk, a streamer tape with a data rate of 160K bps for disk media backup, and a workstation that allows output to bypass the screen and go directly to the printer.

According to the company, the new models represent performance upgrades for the existing Model 3 and Model 5 and feature improved job scheduling, optimized shared-file performance, enhanced memory management, and new block loading and file accessing techniques for the Escort programming language. Models 3 and 5 can be upgraded to match the capabilities of the new models.

Models 4 and 6 support the Unis 80, Unidis Wholesale, WAMS 80, Univfacs 80, and AMS 80 software systems.
