The ND-5000 family is the third generations system based on the ND-500 architecture. It is a totally new construction both in hardware and physical layout. The ND-5000 CPU uses the same instructions as the ND-500 CPU but adds 25 new instructions called '87 extensions', also found in the ND-500/1 and ND-500/2 CPUs.
The new ND-5000 CPU replaces 24 cards in the old ND-500 arcitecture. The single processor ND-5700 system have the same computational power as a ND-570 system.
Sold as the ND-5200, ND-5400, ND-5500, ND-5700, and ND-5800. The ND-120 CPU line, which constituted the ND-100 side of most ND-5000 computers, was named Delilah. As the 5000 line progressed in speed, the dual-arch ND-100/500 configuration increasingly became bottlenecked by all I/O having to go through the ND-100.
Sold as the ND-5830 and ND-5850. The Rallar processor consisted of two main VLSI gate arrays, KUSK and GAMP - meaning "Jockey" and "Horse", respectively.
The ND-5000 CPUs came in 3 types. Type 1 had two layers of cards, type 2 had three layers of cards, and type 3 had four layers of cards. Type 1 and type 2 used similar mother boards/baby modules, the difference was that a layer with instruction/data cache and the AAP (Additional Arithmetic Processor) was missing in the type 1 CPUs. The missing AAP meant that on type 1 CPUs floating point operations were performed by the microprogram.
The difference in performance between models was mainly done by 3 methods:
- Select a CPU (Type 1 / Type 2 / Type 3).
- Jumper the master clock speed to Slow (156 ns) or Normal (70 ns).
- Disable or enable a number or performance enhancing caching features.
Different combinations of the above resulted in the different ND-5000 models. The table below illustrates this.
|System||CPU type||Instruction cache||Data cache||Address cache||Smart IfGo cache||WICO (Write in Cache only)||Master clock speed|
The original series of ND-5000 computers came in three different models, ND-5700, ND-5800 and ND-5900. The ND-5900 models are the same as the ND-5800, but with multiple CPUs (2, 3 or 4). Later additions to the family were Compact models, ND-5200 Compact and ND-5700 Compact.
|System||Relative CPU performance||Memory shared (MB)||Memory local (MB)||Data cache (KB)||Instruction cache (KB)||Max disk capacity (GB)|
|ND-5700||8 - 512||2||64||320||29|
|ND-5800||2||16 - 512||4||64||320||29|
|ND-5900 model 2||4||16 - 512||4||2x64||2x320||29|

The ND-5000 Compact series
The ND-5000 Compact series is equipped with:
- ND-110/CX I/O Processor (ND-110 in ND-5200 Compact system)
- Internal disks or a controller for external disks
- One Streamer, 125 MB (Option on systems with external disks)
- One floppy-disk drive (1.2 MB capacity)
- 4 to 6 MB memory
- SINTRAN and utilities
All ND-5000 Compact systems are available in two models: A model with internal disks and B model with external disk option. A models include from one to four internal disks of 125 MB capacity each (called models A1 to A4). ND-5200 Compact system includes an extra model with one 60 MB internal disk (called model A0). Model B versions are delivered with a controller for external disks and can be configured with external disks and magtape.

Updating tool to be used on ND-5000 Compact systems: Part no: 350156 Double Bus Contr. updating tool.
Updating tool to be used on ND-5000, large cabinet version: Part no: 350157 MF Bus Controller updating tool.
Note: The updating tool will be available in limited volume and will normally only be needed when upgrading the ND-5000 CPU.
Setting of the ND-5000 CPU model
Setting of the CPU model has to be done when the ND-5000 CPU has to be upgraded or when the content of the EEPROM in the MF backplane is cleared or lost.
Updating tool for ND-5000 Compact Series
Part no: 350156 Double Bus Contr. updating tool.
In this kit only the special PROM are available.
To be able to set the CPU model, exchange these PROMs with the one on the Double bus controller.
PROM version 27/11 -87
pos 16J, 18J, 16K and 18K
Comment: The MF bus will not be available when these PROMs are used. These PROMs are only to be used during initializion of the MF bus or setting the CPU model on ND-5000 CPU's. To set the CPU model, the command shown below must be used.
========================================================= = MF bus - TEST AND MAINTENANCE PROGRAM - = = INTERNAL VERSION for 5465 (5454) = = November 11, 1987 = ========================================================= - * INITIALIZING MF-BUS MEMORY * - BANK NOT PROPERLY INITIALIZED - NOT AVAILABLE >SET-CPU-MODEL DANGER! YOU CAN DAMAGE YOUR SYSTEM PASSWORD: SLOTNO:6 % Slot position of the ND-5000 CPU CPU:7 % ND-SOOO CPU model ref. list abowe. % Values 2,4,5,7 or 8. - WRITING TO NONVOLATILE MEMORY, PLEASE WAIT - NEW-PASSWORD (Y/N):N
To verify that the CPU model is correct the following command can be used:
>LIST-CONFIGURATION Slotno:6 SLOT 06 : ND 5000 MODEL: 00B STATION NO: 0000708 POWER FAIL DESTINATION: 000001B BROADCAST TYPE: OOOOOOB SPEED: OOOOO1B CPU MODEL: 000007B MASTER CONTROL REG : 000201B LIMITS THAT DEFINE ACCESS-AREAS FOR THIS SLOT
When the correct ND-5000 CPU mode] setting has been set, the normal PROMS has to be inserted again on the MF bus controller to be able to run the system.
- The MF-bus will not be set available when using the upgrading tool. When setting of the CPU model is finished, exchange from the upgrading tool, back to the old MF controller with correct version of the MF PROM's.
- Check what kind of AAP module (Checkpoint 3) is installed and use the correct microprogram according to CPU model. Ref. overview of the ND-5000 microprograms.
- If the updating tool is not available, the following commands in the MF maintenance program must be avoided:
>INITIATE-EEPROM with slot number equal to the MF controller. >CONFIGURATE-SLOT with slot number equaI to the ND-5000 CPU and the configuration is saved.
These two commands will destroy the CPU model setting for the ND-5000 CPU.
