COMPUTING SYSTEM SUMMARY DOMAIN,THE ARCHITECTURE OF THE FUTURE, TODAY A DEDICATED COMPUTER PER USER DOMAIN delivers predictable throughput to each user. A variety of options can be added to tune each DOMAIN Node's performance to individual needs. And DOMAIN's responsiveness won't suffer as more users are added to the network. CONCURRENT PROCESSES, MULTIPLE WINDOWS Separate windows on DOMAIN's high-resolution, bit-mapped display provide "virtual terminals" connected to multiple programs and data. There is no need to wait for one pro- gram's completion before starting another. This new mode of concurrent interaction saves precious time in the soft- ware development and debugging cycle. A RESOURCE-SHARING, MODULAR NETWORK DOMAIN's computing power and peripheral resources are expand- able in stages that are far more affordable than upgrading a conventional mainframe. Programs and data may be shared quickly and easily across the network. The network's fault- tolerant architecture provides high overall system availability. LARGE-MACHINE FEATURES Each DOMAIN Node provides a virtual memory operating system, an extensive command library, and high-level language com- pilers. Connected DOMAIN Nodes cooperate to provide single, network-wide directory for easy access to programs, data, and peripherals. PROFESSIONAL PRODUCTIVITY SYSTEM Productivity no longer depends upon an uncontrollable share of a central mainframe. DOMAIN's user-dedicated Nodes let programmers optimize the use of their valuable time. Con- current editing, execution, and online documentation speed program development. Advanced graphics, coupled with DOMAIN's other features, streamline large-scale applications develop- ment and conversion. HARDWARE FEATURES Each DOMAIN Computational Node is a dedicated, single-user unit composed of three main subsystems. CPU ENCLOSURE o 32-bit architecture VLSI CPU with demand-paging hardware o 512Kbyte main memory with error checking and correction, expandable to 3.5 mbytes o 1024 x 800 pixels high-resolution, bit-mapped display controller with 128Kb refresh buffer memory. Includes 32 megabit/second block transfer hardware o Integral network interface and controller o Three RS-232 asynchronous serial I/O ports for communications at rates up to 19.2 kbaud DISPLAY OPTIONS DN660 DN460 DN300 19-Inch 19-Inch 17-Inch Black&White Black&White Black&White Orientation Portrait Portrait Portrait Display Field Resolution: 1024 x 1024 x 1024 x Pixils 1024 800 800 Refresher Rate 30 60 80 KEYBOARD o Business typewriter key layout, plus 28 software program- mable keys o Detachable coiled cord stretches up to 3.3 feet (1.0 Meter) o Touchpad cursor control included with black and white display o Integral microprocessor o RS-232 serial ASCII output at 1200 baud o Electronic shiftlock and n-key rollover NETWORKING FEATURES o High-performance local area communications o Transparent access to shared programs, data, and peripherals o Gateway access to remote facilities o DOMAIN ring network-dual address packet with single token arbitration o 12 mbit/second baseband transmission o 3280 feet (1000 meters) separation between active nodes o Uses standard RG6/U coaxial cable DISK OPTIONS WITHIN THE COMPUTATIONAL NODE o 34,70, and 168 mbyte winchester disk o 1.2 mbyte diskette drive, 8-inch, double-sided/double-density ADDITIONAL PERIPHERAL SUPPORT All of these options are fully supported by DOMAIN's operating system. o Peripheral-to-node adapter (PNA)-IEEE-P796(Multibus) standard interface/cardcage with five slots for peripheral device controller cards.
