The DSP80A improves a DOMAIN (r) workstation's performance by off-loading the overhead of managing peripherals and communications tasks. The DSP80A is completely software compatible with the workstations and servers on the network. Since the DSP80A performs these administrative functions, user workstations are available for interactive processing. .sp The DSP80A includes its own 32-bit VLSI central processor, up to 3M bytes of main memory, a subset of the AEGIS (tm) network-wide virtual memory operating system, and a five-slot MULTIBUS (tm) card cage. .sp The DSP80A lets a DOMAIN network incorporate larger peripherals, external communications gateways, and specialized subsystems such as array processors. .sp With five IEEE-796 MULTIBUS (tm) card slots and two RS-232C serial ports, the DSP80A can support large-capacity disk drives, gateway communications to external networks, tape drives, and a variety of printers/plotters. Apollo's unique, network-wide virtual memory operating system lets these peripherals respond to users located anywhere in the network as if they were locally attached. Apollo also offers GPIO software to let users prepare and easily install device drivers in a high level language. .sp Apollo supports a variety of peripheral devices compatible with the DSP80A for storage, data interchange, output, and communication. For storage, Apollo provides a removable media 300M byte disk drive (MSD300), and a fixed media 500M byte disk drive(MSD500M). For data interchange, Apollo offers a 1600BPI tape drive (MSD1600). In the communication area, Apollo provides an X.25 and an ETHERNET (r) gateway subsystem. .sp The DSP80A is available as a table top unit, mounted in an Apollo-peripheral cabinet with other Apollo peripherals, or in a rack-mountable kit for placement in a customer-supplied cabinet. .ne 13 .ls 1 .sp 2 {_Features_} .bu .bb o Provides interconnection for peripherals, communications products, and other specialized devices in a DOMAIN network .bb o Compatible with software for all DOMAIN products .bb o Communicates with other DOMAIN systems and off-net environments .bb o Interconnects with industry standard bus for standard peripherals .bb o Supports GPIO software for device drivers .eb .sp {_Benefits_} .bu .bb o Relieves user workstations of overhead processing letting these workstations be more productive at interactive tasks .bb o Provides a centralized mechanism for interconnecting Apollo- or customer-provided peripheral equipment .eb .ls 2 .sp .ne 8 {_Server Workstation_} .sp The DSP80A is a server node that acts as a sharing resource available to any user. As a server, the DSP80A is available to off-load tasks from a user's workstation. Some tasks that run continuously on server processes can be off-loaded to a DSP80A. Since the software is compatible across DOMAIN workstations and servers, any task can be easily off-loaded to a batch type processing node. .sp 2 {_Peripheral Interconnect_} .sp The DSP80A connects peripherals to the Apollo network. Apollo provides hardware and software for connecting tapes, disks, printers, and two separate communication devices. The DSP80A is capable of running the necessary programs to access data, transfer data to/from the peripheral, and controlling the peripherals. Peripherals connected to any node can be shared by other users on the network -- peripherals connected to the DSP80A may also be shared. All control programs run on the DSP80A, freeing up user nodes for tasks that are directly related to running the peripherals. .sp GPIO software facilitates the control of user-provided devices. GPIO software also allows users to prepare drivers for a unique device in high level language and provides protection against accidental data destruction. .ne 8 .sp 2 {_MULTIBUS_} .sp The DSP80A uses the industry-standard MULTIBUS as the interconnect mechanism for both Apollo- and customer-supplied peripherals. The use of an industry standard bus ensures that controllers are commercially available, and that users are readily able to interface to this bus. .ne .sp 2 {_Communications Support_} .sp Communication from one workstation to another is an integral component of DOMAIN System architecture, as is communication between DOMAIN networks. .sp The DSP80A supports a wide range of communications software. .sp Communication with large host systems is supported by the RJE Access Gateway software that emulates several RJE subsystems: IBM's HASP and the standard 2780 and 3780 environments. An ETHERNET gateway provides DOMAIN users with shared access to existing ETHERNET transport facilities. The protocols used for the ETHERNET gateway are Transmission Control Protocol (TCP) and Internetworking Protocol (IP) with the standard Arpanet FTP file transfer service and TELNET remote log in service. .sp The DOMAIN system also fully supports the X.25 protocol for public long haul packet switching networks. .ne 8 .sp 2 {_DOMAIN Product Family_} .sp All members of the DOMAIN Product Family let users transparently share information and resources in the distributed DOMAIN system environment. .sp All members of the DOMAIN Product Family support a wide range of system software, including a growing library of program development and professional productivity tools, support a wide range of peripheral resources, and provide access to other computing environments through communication facilities. Security of data and programs can be provided by selectively controlling access rights. .sp 2 {_Choice of Operating Systems_} .sp All DOMAIN workstations support AEGIS and AUX, Apollo's implementation of UNIX (tm) System III with Berkeley extensions. Users can run UNIX and AEGIS applications concurrently, each sharing access to the common file system. Since applications running under AUX can also issue AEGIS system calls, developers can modify existing UNIX applications to take full advantage of DOMAIN's powerful system architecture. Both AEGIS and AUX applications offer this transparent access to all DOMAIN resources. .sp 2 .ne 5 {_Third Party Software_} .sp An extensive selection of software packages converted for use on the DOMAIN System is available through Apollo's Third Party Software Supplier Program. The program is designed to attract leading third party software vendors whose products provide complete solutions for Apollo customers. Almost three hundred packages are currently available in the areas of finite element analyses, CAD/CAM modeling, logic simulation, statistical analysis, and many others. Several vendors offer various peripheral device and hardware interfaces. The DOMAIN CATALOGUE OF APPLICATIONS contains specific information about most of the available software packages. .sp 2 .ne 5 {_Software Support_} .sp All members of the DOMAIN Product Family support a wide range of system software, including a growing library of program development and professional productivity tools, support a wide range of peripheral resources, and provide access to other computing environments through communication facilities. .sp The DOMAIN software environment also features the FORTRAN 77, ISO Pascal, C, and LISP programming languages. .ls 1 .sp 3 .nf .nj .ne 35 {_Specifications_} .sp 2 CPU data width 32 bits memory capacity .5M byte, 1M byte, 1.5M byte, 3M byte virtural memory yes Peripheral interfaces Serial lines Two RS-232C maximum baud rate 19.2K printer interface One Dataproducts (tm) standard MULTIBUS 5 slots MULTIBUS specifications slots 5 DMA yes speed 2M bytes/second peak burst Masters multiple Specification IEEE P796 D16 M20 I16 VO L compliance Clock speed 8MHZ Software operating system AEGIS, AUX Maximum dma block 64K byte Mechanical height 8.72 in.
