Chapter 1 INTRODUCTION¶
This chapter gives an introduction to the ND-5000 ES C models.
1.1 System description¶
The new ND-5000 ES Model C replaces the current ND-5000 Compact. It covers the low/medium end of the ND-5000 systems and is meant to be used as general departmental systems and servers for installations that are not too large.
It has the same cabinet as the previous version, except for the front cover. The interior, however, is completely new. It consists of a large card crate, into which all cards and devices (including the new power supply, the fan unit, disks, floppy units and streamer units) can be plugged. The backwiring is located in the middle of the card crate, and cards and devices are plugged in from both the front and the rear sides.
The new ND-5000 ES Model C is available with all ND-5000 CPU versions, including ND-5800.
See the table on page 2 for an overview of the various systems available.

Chapter 2 Physical Description¶
This chapter describes the different parts of the hardware in the new ND-5000 ES Model C. This is a physical description, and will not cover functional descriptions of the different parts described in this chapter:
- Cabinet
- Panels
- Power switch
- Backwiring
- Fan tray

Page 15¶
Chapter 2 Physical Description¶
2.1 Cabinet¶
This section describes the cabinet, including the card crate, the power supply and the devices.
It is easy to replace defective devices and modules, as the parts that normally need service are plugged directly into the backwiring and the cabinet is practically free from internal cables.

Chapter 2: Physical Description¶
2.1.2 Fan Tray¶
The cooling is based on the same principle as the previous ND-5000 Compact. The fans are located in a fan tray pluggable from the bottom of the front into the backwiring (see figure 4). The fans are the DC type, with an extra wire for indicating the rotation speed. The power for the fans is supplied by the DC 500 power supply, and the voltage is controlled by software and the ambient temperature. The input to the fan speed control comes from an NTC resistor which senses the room temperature. This sensor is mounted at the top of the backwiring, close to the air inlet.
NOTE
Note that you must turn the power off
before removing or inserting the fan
tray.
2.1.3 Operator Panel¶
The operator panel and key switch are located at the top of the front (see figure 4). It is similar to the operator panels on previous ND computers, but the display has been removed. The information that earlier could be read from the display is still available, but you must connect a maintenance display to get it (see page 42). The operator panel is connected to the backwiring via a flat cable along the top of the cabinet.

Chapter 2 Physical Description¶
2.1.4 Backwiring¶
The backwiring acts as the main connection between all internal modules. All cards and devices are plugged directly into the backwiring, including the power supply and the fan tray.
The backwiring also contains:
- Temperature sensor (regulating the fan speed)
- Connector for the operator panel
- An area where it is possible to measure the voltages
- Terminator/strap fields for the SCSI bus
- Switches for splitting the SCSI bus
The backwiring is prepared for taking care of the internal SCSI bus. This bus has been routed to all internal SCSI devices, and it ends up on the plugboard in position 14. Here the bus can be terminated, or one external single-ended SCSI device can be connected. This could, for example, be a magtape unit used for backup.
Normally all devices on the SCSI bus can be accessed from ND-100, but the strap/terminator fields and the split switches on the backwiring make it possible to split the SCSI bus. See the description in the section "SCSI bus" on page 14.
Two different versions of the backwiring are used:
- PCB number 5812 for early versions
- PCB number 5816 for later versions
The difference between these two backwirings is the possibility to split the bus with
Page 21¶
Chapter 2 Physical Description¶
straps/terminators and split switches. See the illustrations of the backwirings (figure 5 and figure 6) and the description in the section "The SCSI bus" on page 14.
Unused SCSI positions must be terminated by a dummy plug, part number 322774.

2.1.4.1 SCSI Bus¶
The SCSI (Small Computer Systems Interface) standard is used for connecting mass storage devices to the computer. A maximum of eight units can be connected to one bus (including the ND-100 SCSI controller).
On the ND-5000 ES Model C, the backwiring takes care of the internal SCSI bus. This bus has been routed to all internal SCSI devices (streamer and disks), and it ends up on the plugboard in position 14 (see figures 7 and 8).
Here the bus can be terminated, or one external single-ended SCSI device can be connected. This could, for example, be a magtape unit used for backup.
To be able to separate the different SCSI units from each other, each unit connected to the SCSI bus must have its own SCSI identification number (ID number). These numbers are 0-7, and they are set by switches or straps on each device or board.
| ID number | Device | See page |
|---|---|---|
| 0 | Disk A (system disk) | 31 |
| *) 1 | Streamer or ND Gigatape | 32 |
| 2 | Optional external SCSI device | |
| 3 - 6 | Free (Disk B-E) | 31 |
| 7 | ND-100 Floppy and SCSI controller | 39 |
*) SCSI ID number 1 is reserved for the device used for system disk backup.
Page 25¶
Chapter 2 Physical Description¶
All devices on the SCSI bus are normally accessed from the ND-100, but there are several possible ways to split the access to the SCSI devices. This is done with strap fields and split switches in the backwiring (see figure 5 and figure 6) and a flat cable on the System plugboard - 5259 (see figure 22).
On the next pages we show three different examples of how to do this on both versions of the backwiring.

Chapter 2 Physical Description¶
This can be done as described below:
- An MF bus SCSI controller (MF bus SCSI controller I) must be placed in MF bus position 8 in the card crate (positions 5, 6 or 7 may also be used, but then you must use an extra plugboard in the backwiring and a flat cable).
- Another single-ended MF bus SCSI controller (MF bus SCSI controller II) must be placed in MF bus positions 5, 6 or 7, and a SCSI plugboard must be placed in the same position from the rear side.
- The strap fields on the backwiring must be set as shown in the figure on the next page.
- The split switches on the backwiring must be as shown in the figure on the next page.
- The flat cable on the System plugboard must be connected as shown in the figure on the next page.
- A cable must be connected between the two plugboards.
- Empty SCSI positions must be equipped with dummy plugs, part number 322774.

2.1.7 Power Supply¶
The new DC500 and DC501 power supplies are equipped with a microprocessor. Voltages, currents and the fan speed can be monitored and adjusted via a terminal or via TELEFIX.
The power supply also checks that all fans in the fan tray are running.
A temperature sensor, mounted on the top of the backwiring, checks the temperature inside the cabinet. If the temperature increases, the power supply feeds the fans a higher voltage to increase the fan speed, and that reduces the temperature.
The power supply has the following capacities:
| Voltage | Amperes |
|---|---|
| + 5 Volts | 150 Amperes |
| + 5 Volts standby | 8 Amperes (DC501: 12 Amperes) |
| +12 Volts | 18 Amperes (25 Amp. peak to start up disks) |
It is not necessary to perform any maintenance or adjustments on the power module. If the module is defective, it must be replaced.
The power supply is the plug-in type and is therefore easy to replace: Turn the key switch on the operator panel to OFF and turn the power off. Disconnect the two cables from the power supply, unscrew the two screws holding the power supply and pull it out.

2.1.8 Boards¶
This section describes new boards that are unique to the ND-5000 ES Model C, controllers or plugboards. Other ND-100 cards and cards in the MF bus are not described here, since they are described in other manuals.
Plugboards are plugged into the backwiring from the rear of the cabinet, and this means the computer is almost cable-free.
Some of the plugboards are delivered with every system, while others are optional depending on the model and configuration.
The purpose of this brief description is to show the plugs and switches on the boards.
Page 47¶
Chapter 2 Physical Description¶
System Plugboard (5259)¶
This board is used to connect the following devices:
- Maintenance display
- External SCSI device
- ND-5000 CPU console
- ND-100 console
- TELEFIX modem
The plugboard also contains switches for baud rates for the consoles and a switch for enabling/disabling TELEFIX. It is delivered with every system and is placed in the leftmost position in the backwiring, seen from the rear side.

8-terminal plugboards¶
There are two different types of plugboards for the 8-terminal interface:
-
PCB 5261 (8-terminal plugboard) is plugged into the backwiring from the rear side, normally in position 1. Because of the size of the plugboard, it is not possible to plug other plugboards into position 2. Up to eight terminals can be connected to this plugboard.
This board is normally used when eight or fewer terminals are connected.
- PCB 5262 (Plugboard for external panel) is plugged into the backwiring from the rear side in one of the free I/O-positions. This plugboard is connected to an external plug panel (PCB 1701) via two cables (see figure 25). PCB 1701 is mounted in a frame on a wall in the data room. Up to eight terminals can be connected to PCB 1701, and each frame can take up to eight external plug panels.

Chapter 3: Maintenance Display¶
Since there is no display on the operator panel of the ND-5000 ES Model C, you must use an external maintenance display. It is similar to the display part of the first ND-100 operator panels, but there is no OPCOM button (see the figure on page 43).
Connection¶
Connect the display to the upper socket in the system plugboard (5259), which is located in the leftmost position in the backwiring, seen from the back.

3.1.1 Normal Display Operation¶
In normal conditions, the different parts of the display operate as described in this section.
The FUNCTION Field:¶
The four parts of the FUNCTION field show the following:
UTIlity¶
The UTIL part shows the utility of the ND-120 CPU. The more the ND-120 is utilized (that is, the less time spent on program level 0), the more segments are lit.
| | |------| |-\\ |------|
| | | | | \\ | |
| | | | | \\ | |
| | | | | \\| |
| | | | | \\ |

Chapter 3 Maintenance Display¶
Interrupt/paging MODE¶
The MODE part shows whether the interrupt system and/or the paging system is turned on.
lP l
Both the Interrupt and Only the interrupt sys-
paging systems are on. tem is on.
The ADDRESS field¶
The ADDRESS field displays the DAY, HOUR, MINute and SECond taken from the system clock. (See figure 27 on page 43.)
The DATA field¶
The DATA field shows the active program level in the computer. A "one" is set in one of the positions 0-15, corresponding to the active level. The display has afterglow, so it is possible to see a single instruction on a program level. (See figure 27 on page 43.)
The OPCOM indicator¶
As the name indicates, the OPCOM indicator is lit when the computer is in OPCOM mode.
Page 56¶
Chapter 3 Maintenance Display¶
3.1.2 OPCOM Commands Using Display¶
Some of the commands available in OPCOM use the display. A summary of how they affect the display is given here. For a complete explanation of OPCOM etc., see the manual ND-110 & ND-120 Functional Description (ND-806030).
Why Use the Display?¶
Much of the same information is shown on both the console and the display. But the display remains in the same mode afterwards, and is continuously updated. Therefore you can set up the display to examine for example register or memory address, leave OPCOM, start a program, and still see what happens in that register or address.
Memory Examine¶
Display¶
When you examine memory, the display responds like this:
- FUNCTION field: examine mode
- PEXM = Physical address examine
- PT 0 - PT17 = Logical address, mapped via page table 0 - 178.
- ADDRESS field: Memory address.
- DATA field: Contents of current address.
Page 57¶
Chapter 3 Maintenance Display¶
Examine Mode¶
First, set the memory examine mode. If you want to use physical addresses, give the OPCOM command:
#E↓
If you want to use logical addresses, specify the number of the desired page table (0 - 178) before the "E".
Example:
#2E↓
Subsequent addresses will be mapped through page table 2.
Memory Examine¶
To examine a location in memory, type the address followed by a /. The display remains in this mode until you give a new display command.
Example:
#E↓
#12345/ 54321
The contents of physical address 123458 is now 543218. This is shown on both the console and the display. If it is changed by a running program, the new contents will be shown on the display.
Page 58¶
Register Examine¶
In register examine mode, the display shows:
FUNCTION field: Name (and program level if specified) of the register.
ADDRESS field: Current Program Counter (PC). Updated continuously.
DATA field: Contents of register. Updated continuously.
Working Registers¶
To examine one of the working registers, type:
#xxRy/
- xx = Program level (0 - 178). Default is program level 0.
- Ry = Working register name R0 - R7. Corresponding to register-file working registers STS, D, P, B, L, A, T, and X respectively. (These names can also be used directly, but STS must be abbreviated to S.)
Example:
#14R0/ 000043
The contents of R0 (STS register) on program level 14 is now 43. This is shown on both the console and the display. If it is changed by a running program, the new contents will be shown on the display. In addition, the display shows the current program counter (also updated continuously) and the name and level for the register.

| PC: 12466 | 43 |
+-------------+----+
Internal Registers¶
To examine one of the internal registers, type:
#Iy/
y = internal register number:
| Number | Register |
|---|---|
| 0 | PANS |
| 1 | STS |
| 2 | OPR |
| 3 | PSR |
| 4 | PVL |
| 5 | IIC |

| 11 | ACTL |
| 12 | ALD |
| 13 | PES |
| 14 | PCR |
| 15 | PEA |
Example:
#I7/
This input on the console will show the contents of the PIE-register on the console and the display. Changes will only be seen on the display.
User Register¶
The user register is used by some diagnostic and utility programs to hold current status information. To examine this register, type
#U/
Page 60¶
Chapter 3 Maintenance Display¶
Reset to Normal Operation¶
| OPCOM input | The command |
|---|---|
| #ACT/ |
resets the display to the normal operating mode, which is described beginning on page 44.
| Master Clear | The display is also reset to normal operation by a Master Clear to the ND-100. |
Define Display Format¶
| OPCOM input | #uuzzyxFJ |
|---|---|
This command sets the format for the display of data. If the parameters uuzzyx are omitted, the default is octal format.
Parameter Explanation¶
-
x : Number representation code.
- x = 0 Displayed data is in octal format. zz has no effect.
- x = 1 Displayed data is in unary format, i.e. four of the bits in the displayed data are used to light one out of 16 indicators.
- x = 2 Displayed data is in binary format. zz has no effect.
-
y : "Stretch" code (afterglow).
- y = 0 No stretching
- y = 1 Zeros are stretched
Scanned by Jonny Oddene for Sintran Data © 2011
Page 61¶
Chapter 3 Maintenance Display¶
y = 2 Ones are stretched
y = 3 Zeros and ones are stretched
zz : Lower start bit for unary display.
zz = 0-248 Position of lowest bit
to be represented in unary format.
uu : Display processor maintenance codes.
| uu | Description |
|---|---|
| 1 | Display year and month in the ADDRESS field |
| 2 | Inhibit message |
| 4 | Initialize panel processor |
| 108 | Abort message |
(See "ND-110 & ND-120 Functional Description" for details on displaying messages on the display.)
Example
1421FJ¶
After this command is given in OPCOM, bits 148-178 are shown in unary format with afterglow on ones.
