June 8, 1992 -- Dayton, Ohio -- In support of its commitment to the
real-time market, Systran Corp. announced today the Model R1600 rehostable
network interface. With the introduction of the Model R1600, any bus
architecture -- even those of obsolete, proprietary or not-yet-invented
computers -- can be integrated into the SCRAMNet real-time replicated
shared-memory network. The Model R1600 was developed in response to
customer requests for SCRAMNet support of low-volume, aging or proprietary
computer systems used in such real-time applications as simulation,
telemetry and process control.

Said W. Lynn Trainor, president of Systran, "The introduction of the R1600
puts into the customer's hands the ability to integrate a real-time system
using virtually any mix of computer systems, even those not yet invented.
We believe no other real-time network provider can make this claim."

With the Model R1600 interface, system architects can quickly and
cost-effectively integrate bus architectures that are not directly
supported by Systran into the SCRAMNet network. For example, to connect an
Intel IWARP computer to a MicroVAX and a VME-based real-time computer
system, a customer could use SCRAMNet's existing Q-bus and VME-bus-based
interfaces, and the Model R1600 to connect the non-standard IWARP memory
bus.

The compact, rack-mountable Model R1600 houses the SCRAMNet network
interface and a general-purpose interface port. A separate adapter board
in the host system contains all of the circuitry necessary to meet
host-specific bus requirements. The customer designs the host adapter,
with Systran supplying interface specifications for the register and
memory port on the Model R1600, and other technical support.

The Model R1600 maintains full SCRAMNet functionality and compatibility,
offering the same low data latency, 150 Mbit/sec. speed, deterministic
performance and ease-of-installation as other SCRAMNet interface
products.

SCRAMNet Designed for Simplicity, Speed SCRAMNet, the leading real-time
distributed network, is optimized for simplicity and speed. With
SCRAMNet's replicated shared-memory design, all computer nodes on the
network are equipped with identical computer-addressable memories. Every
change to the replicated shared-memory at one node is immediately and
automatically repeated in all nodes on the network in microseconds,
causing all computers to appear to real-time applications as one large
virtual multi-processor. Featuring fiber-optic technology, a sophisticated
interrupt structure, data filtering and a programmable byte swapper, the
SCRAMNet network avoids the limitations of physical shared-memory
architectures and message-passing LANs to deliver true real-time speed,
deterministic performance, and positive system control with no software
overhead.

Pricing and Availability The SCRAMNet Model R1600 rehostable network
interface is available now for $6,700 to $9,600, depending on memory size.
In addition, options are available for internal dual link and fiber-optic
bypass switch options. 

An established research and development firm headquartered in Dayton, Ohio,
Systran Corp. specializes in simulation, artificial intelligence and
defense-related hardware/software research and development. The company's
SCRAMNet network is the leading real-time network, with hundreds of nodes
