DOMAIN PROCESSING - A NEW FORM OF INTERACTIVE COMPUTING
A DEDICATED CPU PER USER:
Each user experiences a high level of predictable performance,
through his own VLSI cpu with 32 bit architecture, and an
advanced network oriented operating system.
MULTIPLE PROCESSES PER USER:
A new mode of man-machine interaction, comprising a high
resolution bit-map display and display manager.
Multiple programs run simultaneously for the user,
with a window for each being displayed on the screen.
A RESOURCE SHARING MODULAR NETWORK:
Computational power and peripheral resources are added to
the network in easy stages as the level and shape of an
installations requirements develops. Not only is economic
growth possible, but network resilience provides high levels of
overall system availability.
DOMAIN PROCESSING - AN INTEGRATED SOFTWARE &
HARDWARE SOLUTION FOR INCREASED PROFESSIONAL PRODUCTIVITY
ENGINEERING/GRAPHICS WORKSTATION:
With up to 16 Mbytes virtual address space per process,
an extensive command language and high level language compilers, migration and
development of large scale applications is easily achieved.
Accessing these dedicated mainframe style facilities via the
advanced graphics capabilities of the DOMAIN display can provide
efficiency improvements unattainable with conventional systems.
PROGRAMMERS WORKBENCH
Rationed CPU access can throttle programmer productivity - not so
with DOMAIN, where the availability of a dedicated CPU combined with
operating system capabilities which enable concurrent access to multiple
processes for editing, execution and documentation functions greatly
enhances personal throughput.

Cabling: Coaxial
Node separation: l000m maximum
Access to other networks via gateway node
Note:
The first node in a DOMAIN network requires a Winchester disk and a diskette;
subsequent nodes may not need these devices, depending on the application
requirements.
Additional Hardware
Multibus Interface/Cardcage: to proposed IEEE standard, has five card
slots for storage module, line printer, magnetic tape control or other
user purposes.
300 Mbyte storage module drive: fully removable disk storage
300 lpm printer
600 lpm printer
25/100 ips file/streamer magtape
60 cps letter quality printer
All the above hardware items are fully supported by the operating system.
SOFTWARE SPECIFICATION
Operating System (AEGIS)
Multiprocess network object oriented demand paged virtual memory system
with up to 16 processes per node and up to 16 Mbyte per process.
All the following software items are integrated with and operate
under AEGIS
Display manager: handles concurrent display of, and relationship
between multiple windows and a processes virtual terminal (PAD),
together with multiple fonts.
Binder
Pascal compiler: to proposed ANSI standard
Fortran 77 compiler: to ANSI standard with extensions.
(Compilers generate directly executable code; system references are
dynamically linked at run time. Source program objects, compiled objects and
bound objects can be resident anywhere on the network.)
Software tools library: UNIX like user interface
Stream I/O for process/device/file interconnection
Shell programming for application control
Editors
File management system
DOMAIN is developing rapidly and continuously. Please check the current
