ND 505/CX COMPUTER SYSTEM¶

for Commercial and Technical/Scientific Applications

INTRODUCTION¶

The ND-505/CX system is based upon the ND-500/2 Central Processor. It has 29 bits addressing space available to the user. The architecture of the ND-500/2 CPU accommodates exceedingly large programs and data areas. A Prefetch Processor handles the fetching of data from the multiport memory system and the instruction pipelining. Together, these features make the ND-505/CX one of the most advanced supermini computer systems available.

The basic ND-505/CX Computer System consists of an ND-500/2 CPU, an ND-100 Front-End Processor, a Controller, a System Console and a Main Memory of 2 1/4 Megabyte. It also includes the SINTRAN III multituser, multimode operating system, which performs input/output, job scheduling and resource allocation.

FEATURES¶

Processor Technology
Implementation in FAST TTL and LSI logic.

BCD Arithmetic
A full BCD Arithmetic and conversion processor gives high speed COBOL processing.

Advanced Instruction Repertoire
Instructions are byte-oriented and tailored for high-level program execution efficiency, such as FORTRAN DO-loops and COBOL string-handling.

Large Program Size
The ND-505/CX memory management system allows each user an address space of up to 1/4 Gigabytes for programs.

Large Data Space
Each user may use up to 1/4 Gigabyte for data. This means that files may be accessed as if they were arrays, thus allowing the hardware memory management system to access data, rather than the more resource-consuming file system.

Multiprogramming
Through the use of its efficient virtual memory system and its SINTRAN III Operating System, the ND-500/2 CPU may be shared by many programs. Context-switching routines are implemented in the microcode.

Multiport Memory System
The main memory system is of the multiport type. This allows sharing and direct access for the ND-500/2 CPU, the ND-100 Front-End Processing Unit, and DMA devices such as disk and magnetic tape, and high performance communication links.

SINTRAN III Operating System
This is Norsk Data's interactive, terminal-oriented operating system. It allows many programs written in many languages to be executed simultaneously. Real Time tasks, local and remote batch jobs and other types of data communication may also be run concurrently with the timesharing users.

Basic Configuration¶

The ND-505/CX Computer System is housed in one cabinet. The system includes the ND-500/2 CPU, the Multiport V Memory System, the ND-100 Front-End Processor and the I/O system.

The system includes a disk controller and interface, a floppydisk unit with controller and interface, a console hardcopy terminal with interface, and the SINTRAN III Operating System. Any disk system from 70 MB and upwards may be added according to the configuration rules.

There are 12 free I/O slots in the basic system for peripheral controllers and interfaces, i.e., terminal ports, magnetic tape, communications ports, etc. Any ND-100 peripherals may be attached.

The memory supplied with a basic ND-505/CX system is 2-1/4 Megabytes. 1/4 Megabyte is local for the ND-100 Front-End Processing Unit and the operating system, with the remainder being common to both the ND-500/2 and the ND-100 Front-End Processing Units. The maximum shared memory size for the ND-505/CX system is 8 Megabytes (using 4 MB Modules).
