            APOLLO INTRODUCES THE DSP160 DOMAIN SERVER PROCESSOR



            BOSTON, MASSACHUSETTS, October 26, 1983 -- Apollo Computer Inc.

today announced its new DSP160 server processor, providing a high end

supermini performance computational resource which can be shared throughout 

an Apollo network.

      
            "Users can transparently share the DSP160's powerful computation 

capabilities as well as its ability to manage peripheral resources." stated

Anil Gadre, product manager for the new server. "The DSP160 is an integral 

part of Apollo's DOMAIN  architecture and is compatible with all members of 

the Apollo family of user nodes and servers."


            The DSP160's high performance, proprietary bit slice CPU, with 

integral hardware floating point and two cache memories, give it processing 

power to improve the throughput of computationally intensive applications 

such as solids modeling, finite element analysis, and integrated circuit 

simulation. In addition, since each process of the DSP160 has 256 megabytes 

of virtual address space, application programs requiring a great deal of 

memory can be handled with ease.



            "By offloading computation intensive program segments, the user's 

interactive work is not constrained," added Gadre, "thus  improving the level 

of personal productivity. Users throughout  the network may share the high end

server's processing capabilities  and experience an increase in throughput 

for the entire  network of nodes."      


             The full 32 bit proprietary architecture combined with up to 4 

MB main memory and a 256M byte virtual address space makes the  DSP160 ideal 

for applications previously requiring expensive  and very large supermini 

systems. The processor's integral floating point unit combined with 3 stage

pipelining and separate data and instruction cache memory provides the high 

processing speed needed for reducing large data sets and performing complex 

manipulations. 


            The DSP160 can support a 68MB or a 157MB integrated
                                                  *
Winchester disk, and provides an optional MULTIBUS  card cage, offering

interfaces to other devices. A 300MB drive is also available, and

three RS232C ports are standard.


            Apollo Computer is the creator of DOMAIN Processing, the 

concept of distributed computer power over a local area network of dedicated, 

high-performance, 32-bit engineering workstations.  The product is used in 

aerospace research, civil engineering, chemical engineering, interactive 

computer-aided engineering, software design, financial modeling, statistical

analysis, and computer science education. The company, headquartered at 

15 Elizabeth Drive in Chelmsford, MA, has 21 full service and sales 

offices in the United States and 6 international offices serving Europe, 

the Middle East, and the Far East.
