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.

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. Dedicated power and cooling.
o General-purpose I/O (GPIO) software package - for PNA users
who wish to develop their own peripheral device drivers.
o Up to two 300 megabyte, removable media, storage module
disk drives may be connected to a Computational Node for
shared storage service.
o 1600 BPI/25 IPS magnetic tape subsystem
o 60 CPS letter-quality printer
SOFTWARE FEATURES - AEGIS OPERATING SYSTEM
Object-oriented, virtual memory operating system supports up
to 15 concurrent processes on each Computational Node. Objects
of size up to 2(32) bytes are demand-paged from local disk
storage and remotely across the network.
AEGIS SOFTWARE COMPONENTS
o Interactive display manager presents output from multiple
concurrent processes. Includes a comprehensive screen-
oriented editor. Supports display of high-resolution
graphics and multi-font text.
o Interprocess communication, process creation, and event
synchronization to coordinate the execution of separate
programs.
o Network-wide hierarchical directory structure with access
control list protection mechanism.
o Shell command line interpreter for application control: An
interactive programming language whose "Verbs" are user
and utility programs.
o Redirectable stream I/O for network-wide process/device/
file interconnection.
o Software tools utility program library to speed application
development.
HIGH LEVEL LANGUAGES
o Pascal compiler conforms to proposed ISO standard plus
extensions.
o FORTRAN-77 compiler conforms to ANSI standard plus
extensions.
o C compiler.
o Lisp compiler
o Online, high-level language debugging tool.
