This chapter also describes the following memory modules: MSVll-PKI-PL
and MSVll-QAI-QB/-QC.
The KDJll-S/D is designed for systems that use the extended LSI-ll bus,
commonly called the Q22-bus. The KDJll-D/S uses either the MSVll-P
or MSVll-Q memory module(s) and a set of standard Q22-bus options.

KOJ11-0/S CPU Description

1.2 KDJ11 DIS Overview
A system that contains a KDJ11-D/S CPU module is called a MicroPDP11/53 system.
The KDJ11-D/S (M7554!M7554-P) is a quad-height module based on the
DCJ11 microprocessor chip. The module operates at either 15 or 18 MHz
and includes the CPU, memory management, local memory, a console serial
line unit (SLU), and a printer port SLU.
The KDJ11-D/S executes the PDP-11173 instruction set. The floating point
instruction set is standard, but the floating point accelerator (FPA) is not
an option. The extended instruction set (EIS) is also standard. Three
protection (operating) modes provide full 22-bit memory management for
both instruction and data references: kernel, supervisor, and user.
The KDJ11-D/S can address up to 4 Mbytes of memory. On-board (local)
memory is 512 Kbytes or 1.5 Mbytes of dynamic RAM with no battery
backup. An additional 3.5 or 2.5 Mbytes of memory can be addressed over
the Q22-bus interface. The module's starting address is fixed at zero.
The KDJ11-D is the base module for the -S variants, which are for use in
BA200-series enclosure only.
The KDJ11-D and KDJ11-S modules are functionally identical, but not
interchangeable. The -S variants contain a handle, riveted to the side of
the module, which replaces the internal cabling and I/O panel used in the
BA23 enclosure. When installed with other modules with similar handles or
covers in the card cage of BA200-series enclosures, the handle functions as
a shield for electromagnetic interference (EMIl and simplifies maintenance.
The KDJ11-D (M7554) is shown in Figure 1-1. The KDJ11-S (M7554-P)
is shown in Figure 1-2.

For DU, you boot removable media before fixed-media.
Version 1 (V1.0) supports English and Spanish text only. Switch positions
1 through 5 and 7 through 11 require you to select the desired language.
Version 2 (V2.0) supports English, Spanish, French, German, Dutch,
Swedish, Italian, and Portuguese text. Switch positions 1 through 7 require
you to select the desired language. Switch positions 8 through 11 are
reserved for future languages.
To properly display the text for the various languages, the console terminal
must have certain capabilities:
•

For V1.00 of the ROM code, set up the terminal to display standard
ASCII for both English and Spanish text only. Bit 7 of all input is
stripped to O.

•

For V2.00 of the ROM code, some of the languages require that the
terminal have the multinational character set (MCS) available along
with ASCII. Set up the terminal so that characters from 0 to 127(10)

1-10

KDJ11-D/S CPU System Maintenance

select ASCII, and characters from 128(10) to 255(10) select MCS. Some
languages use 8-bit input also.
Table 1-4 lists the terminal requirements for the various languages.

CPU Module User's Guide.

1.4 Boot and Diagnostic ROM Code
Bootstrap and diagnostic programs reside in two ROMs or EPROMs on the
KDJll-D/S module. The programs mOM code) test the CPU module and
memory at power-up or restart, and boot the user's software from various
devices.
The ROM code consists of three routines:
•

Diagnostics that run when the ROM code is started. The diagnostics
verify that the KDJll-D/S and any additional Q22-bus memory
modules are working correctly. The test run time is longer when
additional memory modules are installed.

•

Bootstrap routines for most DIGITAL tape, disk, and network products.

•

All support routines and user commands.

KDJ11-D/S CPU Description

1-11

1.5 Automatic Boot Mode
Mter the KDJll-D/S start-up self-test completes, the ROM code
automatically tries to load and start (boot) a program from the user's disk
or tape drive. If successful, the ROM code displays a message at the console
terminal.
Example 1-1 shows a message for a successful system bootstrap in
automatic boot mode. In this example, the software is RT-ll, booted from
device DUO.
Example 1-1:

Successful Automatic Boot Message

98765 4 321
DUO
RT-llFB (S) VOS.Ol

The descending number sequence (top line of Example 1-1) indicates that
the tests are executing. Messages following DUO are generated by the
booted software, not the ROM code. At this point, the ROM code is not
executing and all commands and messages are determined by the user's
software.

1.5.1 Bootstrap Error Messages
If the autoboot is not successful, the ROM code displays an error message
indicating that the autoboot was not successful, but will make continuous
passes until successful or aborted.

There are two types of KDJll-D/S bootstrap error messages: One is
associated with automatic boot mode at power-up or restart, and the other
with the console mode Boot command (Section 1.6.2).
Example 1-2 shows an error message for an unsuccessful system bootstrap
in the automatic boot mode.

When an error occurs in a boot program called with the Boot command, the
ROM code displays one of the following error messages:

1.6 Console Mode
Console mode allows you to select a boot device, list available boot
programs, run ROM tests, obtain a map of all memory and I/O page
locations, and wrap the console SLU to the second SLD.
You can enter console mode in two ways:
•

Depending on the contents of native register (NR) <12:08>, console
mode is entered automatically after testing is completed. In console
mode, the ROM code allows you to determine the execution sequence
by entering keyboard commands through the console terminal.

•

By typing ICTRLC I during testing or the boot sequence; in this case, the
NR bits are ignored.

When you enter console mode, the ROM code displays the message shown
in Example 1-5, then waits for you to enter a command.
Example 1-5:

Successful Power-Up to Console Mode Message

9 8 7 6 5 4 321
C01llmands are Help, Boot, List, Map, Test, and Wrap.

The Boot command allows you to select a boot device. The command uses
arguments and optional switches.
Arguments specify the device name and unit number. The device name is
a two-letter mnemonic that describes the device. An optional third letter
specifies the controller. If you omit the unit number, the program assumes
unit zero.
Enter the Boot command in either of the following two ways:
•

The device name is usually a two-letter mnemonic. The valid letter range
is A through Z.
The unit number range is the valid range for a particular boot program.
The range varies from 0 to 225, depending on the device.
The description, or device type, is the name of the physical device.

1.6.4 Map Command
The Map command displays the current ROM code version number,
determines and displays the size of consecutive memory, identifies all
memory in the system, and maps all locations in the I/O page.
Memory is mapped in l-Kbyte increments from location zero to the I/O
page. The map routine tries to identify the size of each memory module
and its CSR address (if applicable). If two or more noncontiguous memory
modules are present, the ROM code displays their descriptions, separated
by a blank line.
NOTE: If two memory modules share some common addresses or have CSRs
with the same address, the Map command does not work correctly.

1-18

KDJ11-D/S CPU System Maintenance

After all memory is mapped, you are prompted to press IRETURN I
(Example 1-11). Mapping continues and all responding 110 page addresses
are displayed. The 110 page map addresses are 17760000 to 17777776. In
addition, all responding CPU addresses are listed with a short description.
There is no description for addresses that respond and are on the external
bus, with the exception of memory CSRs, if present, and Q-bus devices
DU, MU, and XH. The map only identifies DU (disk MSCP controller)
and MU (tape MSCP controller) at their standard addresses of 17772150/2
and 17774500/2. The map identifies XH at addresses 17774440/56 and
17774460176.
When the on-board line time clock CSR at address 17777546 is reached
during the 110 page portion of the Map command, the ROM code follows
the LTC CSR printout with either BEVENT=O (signal is not present on
Q-busl or BEVENT=1 (signal is present on Q-bus). The line time clock test
does not fail if the BEVENT signal is not present.
When the ROM code detects a device at addresses 17774440 to 17774456 or
17774460 to 17774476 during the I/O page portion of the Map command, it
identifies that device as XH for an Ethernet controller and then reads and
types the six-byte station address starting at either 17774440 or 17774460.
The ROM code prints out in hexadecimal bits 7:4 then 3:0 of each of the six
bytes. The Map command message in Example 1-11 shows one DEQNA
present at location 17774440 to 17774456.

1.6.5 Test Command
The Test command causes the ROM code to run most of the power-up tests
in a continuous loop. The ROM code starts at test 3, runs all applicable
tests and subtests, then restarts the loop after test 6 is completed. To abort
testing and restart console mode, enterlcTRucl at any time. If an error occurs,
the test 3 through 6 error routine is entered. '!\vo actions are possible at
this time:
•

Restart the console mode by entering ICTRUC I.

•

Loop through all the tests, ignoring errors, by typing L IRETURN I.

1-20

KOJ11-0/S CPU System Maintenance

On exiting from the test loop, the ROM code displays the total number
of loops (passes) and the total number of errors (if any) in the following
format, where n is the number of errors and x is the number of times the
tests were attempted:
nnn/xxx

In Example 1-12, the Test command is entered to run all loopable tests.
After four passes, the testing sequence is aborted with no errors.

1.6.6 Wrap Command

....

The Wrap command transmits all input from the console terminal
(DLARTO) to the second SLU (DLARTl), or to a selected SLU. All input
from DLARTI or the selected SLU is sent to the console terminaL This
action allows you, at DLARTO, to communicate with another system
through DLARTI or another selected SLU. The command has one optional
switch: switch IA.
Entering the Wrap command with switch IA causes the ROM code to request
an alternate SLU address. The valid alternate address range is 17776500
to 17776676.
Example 1-13 shows the Wrap command without the switch. The console
wraps to the second SLU at address 17776500.
Example 1-14 shows the Wrap command with an alternate SLU address.

terminals to reprint command lines that are obscured by pressing the
Delete key.

Selects the console terminal as a hard-copy terminal. Affects
output only if you press the Delete key. When you press Delete,
the ROM code identifies deleted characters with / <forward slash)
characters.

1.7 MSV11 P Memory
The MSVll-P memory is a quad-height module that occupies the slot(s) in
the backplane immediately following the KDJll-D/S CPU in slot 1.
The MSVll-P module contains 64K metallic oxide semiconductor (MOS)
chips that provide storage for IS-bit words (16 data bits and 2 parity bits).
The MSVll-P also contains parity control circuitry and a control status
register.

1-22 KOJ11-0/S CPU System Maintenance

The memory module variants and their storage capacities are:
•

MSVll-PK (M8967-K): 256 Kbytes

•

MSVll-PL (M8067-L): 512 Kbytes

You configure the MSVll-P, shown in Figure 1-6, by means of jumpers
and wire-wrap pins. The -PK and -PL modules have the same factory
configuration.
The MSVll-P module has two LEDs that show the following status:
•

A green LED: lights to indicate that +5 Vdc is present.

•

A red LED: lights to indicate that a parity error has been detected.

1.8 MSV11 Q Memory
The MSVll-Q memory is a quad-height module, shown in Figure 1-7, that
occupies the slot(s) in the backplane immediately following the KDJll-D/S
CPU in slot 1.
The MSVll-Q module has a 1, 2, or 4 Mbyte capacity using either 64K or
256K MaS dynamic RAMs. The control status register (CSR) contains bits
used to store the parity error address bits. You can force wrong parity by
setting a bit in the CSR to check the parity logic.

Chapter 2

Configuration
2.1 Introduction
This chapter describes the rules and guidelines for changing the
configuration of a KDJll-D/S system. Before you change a system's
configuration, you must consider the following factors:
Module order in the backplane
Module configuration
Mass storage device configuration
Section 2.2 lists the guidelines for module order and configuration. These
guidelines apply to the KDJll-D/S CPU in the BA23 and BA200-series
enclosures.
If you are adding a device to a system, you must know the capacity of the
system enclosure in the following areas:

Backplane
I/O panel
Power supply
Mass storage devices

-"-

Worksheets for the enclosures (Section 2.5) provide information about
system capacities.

2.2 Module Order
The order of modules in the backplane depends on four factors:

•
•
•
•

Relative use of devices in the system
Expected performance of each device relative to other devices
The ability of a device to tolerate delays between bus requests and bus
grants (known as "delay tolerance'" or '"interrupt latency'")
The tendency of a device to prevent devices farther from the CPU from
accessing the bus

Configuration

2-1

The relative use and performance of devices depends on the application.
This means the order of modules also depends on the application. Most
applications try to balance the use of devices. To achieve maximum system
performance, use the recommended order listed in Table 2-1. The order
is based on the Q-bus DMA transfer characteristics; use it as a guideline.
Make sure you read the rules and guidelines in Section 2.3 for placement
of the CPU and memory modules.

CAUTION: If an option has Q / CD jumpers, check the documentation for
that option for the correct Q / CD jumper settings. An incorrect jumper setting

can cause damage to the option.
When devices do not perform as expected, you can change the recommended
module order to meet the needs of the application. Often, performance
problems involve a device that is heavily used or has a low delay tolerance.
Usually, there are other heavily used devices between the device with the
low delay tolerance and the CPU. In this case, move the problem device
closer to the CPU.

2-2

KOJ11-0/S CPU System Maintenance

2.3 Configuration Rules
Follow these configuration rules when you install or remove modules from
the card cage:
•

Always install the KDJll-D/S CPU module in slot 1.

•

Always install the MSVll-P or MSVll-Q memory module(s) in the
slots immediately following the CPU, beginning with slot 2.

•

Maintain the Q22-bus grant continuity for all Q22-bus devices in the
system. Each Q22-bus slot that comes before a Q22-bus device on the
grant continuity chain must contain an M9047 grant continuity card or
another Q22-bus device.

•

Install modules following the CPU and memory using the sequence
shown in Table 2-1.

•

Refer to the applicable enclosure maintenance documentation for
enclosure-specific guidelines for the 110 panel and configuration of the
backplane.

2.4 Configuration Procedure
Each module in a system must use a unique device address and interrupt
vector. The device address is also known as the control status register
(CSR) address. Most modules have switches or jumpers for setting the
CSR address and interrupt vector values.
Calculating address and vector values is a complex procedure because some
modules use floating addresses and vectors. The value of a floating address
depends on the other modules in the system.
See Microsystems Options for CSR addresses and interrupt vectors for
MicroPDP-ll options. Most modules have switches and jumpers to change
their operating characteristics. For some applications, you may have to
change the factory switch and jumper positions according to the guidelines
in Microsystems Options.
NOTE: Changing the factory positions may affect the operation of the

diagnostics for the device.

Configuration

2.5 Configuration Worksheets
Use the following configuration worksheets, located at the end of this
chapter, to make sure a configuration does not exceed a system's limits
for expansion space, va space, power, and bus loads:
Enclosure

Worksheet

BA23
BA200-series

Figure 2-1
Figure 2-2

If you use standard DIGITAL modules, you will not exceed the limits for
bus loads.

Use the configuration worksheet as follows:
1.

List all the devices already installed in the system.

List all the devices you plan to install in the system.

Fill in the information for each device, using the data listed in Table 2-2
for BA200-series enclosures or Table 2-3 for the BA23 enclosure.

4. Add up the columns. Make sure the totals are within the limits for the
enclosure power supply.

Troubleshooting
3.1 Overview
This chapter describes the KDJll-D/S CPU power-up self-test procedure
and error messages.
NOTE: The XXDP V2 diagnostic monitor is described in the XXDP User's

Manual.
Read the Troubleshooting section of the customer documentation before
using this chapter. Many apparent system problems have simple causes,
such as incorrect external cabling or monitor settings. Always check for
obvious problems before troubleshooting the system.
The KDJll-D/S CPU and most option modules run self-tests when you
power up the system. A module self-test can detect hard or repeatable
errors, but not intermittent errors.
The LEDs on the module indicate test results. A successful module self-test
does not guarantee that the module is performing correctly, because the test
checks the controller logic only. The test does not check the module's Q22bus interface, line drivers and receivers, or connector pins. An unsuccessful
module self-test is accurate; the test does not require any other part of the
system to be working.
Refer to Microsystems Options for a description of self-tests for individual
modules. For detailed information, including the contents of the command
status register (CSR) of the module's Q22-bus interface, see the user's guide
for the module.

3.2 General Procedures
System problems are generally of two types:
•

The system fails to boot (Section 3.2.1).

•

The system boots, but a device in the system fails (Section 3.2.2).

Troubleshooting

3--1

You should ask two questions before troubleshooting any problem:
•

Has the system been used before, and did it work correctly?

•

Have changes been made to the system recently?

Two common problems occur when you make a change to the system:
•

Cabling is incorrect.

•

Module configuration errors (incorrect CSR addresses and interrupt
vectors) are introduced.

When you troubleshoot problems, note the status of cables and connectors
before you perform each step. Since cables are not always keyed, you can
easily install them backward, or into the wrong connector. Label cables
before you disconnect them, to prevent introducing new problems that make
it more difficult to diagnose the original problem.

3.2.1 System Fails To Boot
The KDJl1-D/S CPU module self-test is described in Section 3.3. If the
system fails (or appears to fail) to boot the operating system, then load and
boot the XXDP diagnostic monitor.
If you cannot boot XXDP V2, do the following:

•

Check the console terminal screen for an error message. Error messages
are listed in Section 3.3.

•

If no error message appears, make sure the on/off power switches on
the console terminal and the system are set to on (1). Check the DC
OK light on both, if applicable.

•

Check the cabling to the console terminal.

•

Check the hex display on the CPU VO panel. If the display does not
light, check the CPU module's LEDs and the CPU cabling. If a hex
error message appears (F through 1) on the VO panel or the module,
see Section 3.3.

•

If the console terminal remains off, check the power supply and power
supply cabling.

If you can boot XXDP V2, and the system passes all tests, then the fault
may be in the operating system.

3-2 KDJ11-D/S CPU System Maintenance

3.2.2 System Boots, but Device Fails
If the system boots successfully, but a device seems to fail or an intermittent

failure occurs, run the XXDP diagnostic monitor to isolate the failure to an
FRU. The failing device is usually in one of the following areas:
CPU
Memory
Mass storage
Communications devices
Here are some common indications of an intermittent or device-specific
problem:
•

Operating system error messages appear at power-up for a particular
communications device.

•

Periodic operating system error messages indicate that a device is not
present or cannot be found.

•

Periodic data loss or scrambled data occur on one or more
communications lines.

•

Attached devices either do not work, or work incorrectly.

•

The system cannot communicate with another computer.

3.3 KDJll DIS Self-Test
The KDJll-D/S CPU is configured at the factory for automatic self-test
and boot mode. The self-test is stored in boot ROMs, and runs each time
the system is turned on or restarted. The self-test performs tests on the
following:
CPU
Memory
Connections between both CPU and memory modules and the Q22-bus
The self-test first tests a small portion of the CPU module, then
progressively tests the rest of the system. The system enters automatic boot
mode (Section 1.5) upon successful completion of the self-test. If the selftest discovers an error or failure, the system displays a message. Table 3-1
lists and describes the start-up self-test error messages.

If any part of the self-test or boot diagnostics fails, the system normally
displays a message in three locations:
•

On the console terminal

•

On the KDJll-D/S LEDs

•

On the SLU panel

Sections 3.3.1 through 3.3.4 explain the KDJll-D/S self-test results.

3.3.1 Test 1
When started, the ROM code runs a series of tests that verify the basic
MMU operation and verify the ROM code. The comprehensive error
message display routines are disabled at this point in the testing sequence.
If an error occurs during test 1, the ROM code displays the following error
message:
KDJll-D/S 1.00

This message indicates that a fatal error condition occurred. The ROM code
ignores any keyboard input, except to redisplay the error message each time
input is received.

3 4 KOJ11-0/S CPU System Maintenance

3.3.2 Test 2

Test 2 checks the console SLU. When the SLUO test is running, the ROM
code assumes that error messages cannot be displayed. Therefore, if an
error occurs, the ROM code loops on the error.

3.3.3 Tests 3 through 6
Tests 3 through 6 are the main CPU and memory tests. These tests
continuously loop when you enter the Test command. If an error is detected
during these tests, the ROM code displays a brief error message.
If an error occurs and you did not select a language, the ROM code prompts
you for a language, then displays the error message. In Example 3-1, the
user selected English at the language inquiry prompt. Note that each line
of the language inquiry displays the associated language.

3.3.5 Octal Debugging Technique (ODT) Mode
You enter console octal debugging technique (ODT) mode in one of three
ways:
•

By pressing the console terminal Break key if halt-on-break jumper
Wll, located on the CPU module, is not installed or halt-on-break
switch is not disabled. Also, make sure you enable the Break key on
the terminal.

•

By executing a Halt instruction in kernel mode, if halt option jumper
WI on the CPU module is installed.

•

When the Q22-bus BHALT line is asserted on the backplane.

When the system enters console ODT mode, it displays the following on the
console terminal:
nnnnnn
@

The number nnnnnn is the contents of PC (R7), and @ is the ODT prompt
character.
ODT consists of commands and routines to find error conditions and to
communicate with the system. You can examine or modify the contents of
the system's registers and memory locations by entering ODT commands.
The console ODT commands are listed and described in Table 3-3.

A.1 Disk Formatting
Format an RD- 01' RX-series disk drive as follows:
CAUTION: Do not format disks without first backing up the data. The

disk formatting procedure destroys previous disk contents.
1.

Insert the formatter diskette 01' the tape cartridge into its drive. Press
1RETURN I.

Type R ZRQx?? after the. (period) prompt; x is B for RQDX1 or RQDX2,
C for RQDX3, and F for RX33. The question marks allow you to use
any revision of the program. Press 1RETURN I.
NOTE: When formatting an RD52 drive, make sure you have Version
CO or later. Earlier versions format the RD52 (31 Mbytes) as though it

were an RD51 (11 Mbytes).
A prompt similar to the following appears on the terminal:
DR>

To run the program, type START and press 1RETURN I. The following dialog
takes place:

Type Y (yes) and press 1RETURN I.
(Section A.1.l).

This activates the reformat mode

NOTE: The program requires about 12 minutes to format an RD51 and
about 30 minutes to format an RD52 or RD53. Typing N (no) doubles

the time required to format the disk drive.
CONTINUE IF Bpn BLOCK INFORMATION IS INACCESSIBLE?

Type Y and press 1RETURN I.
ENTER A NON-ZERO SERIAL NUMBER:

Type your serial number (located on top of the disk drive) and press
1RETURN I·

FORMAT BEGUN

Mter about 12 minutes, the system displays a completion message as
follows:
FORMAT COMPLETED

If the formatting is not successful, the system displays a message when the
error occurs (Section A.1.2). Remove the diskette or tape cartridge if the
formatting has completed successfully.

A.1.1 Format Modes
The program can run three types of format modes: reformat, restore, or
reconstruct. In order, the program asks you the following questions. Your
answers determine the format mode that runs.
1. Use existing bad block information?
2. Down-line load?
3. Continue if bad block information is inaccessible?

The second question does not appear unless you answer N to the first
question. Answering N to the third question causes the diagnostic program
to stop and print a message if a problem is found.
The format modes operate as follows:
•

Reformat mode. If you answer Y to question one, no further questions
are asked. The format program reads the manufacturer's bad blocks
from a block on the disk. It then formats the disk except for these bad

A-2

KDJ11-D/S CPU System Maintenance

----

blocks. The process requires about 12 minutes. If the program fails,
try restore mode.

•

Restore mode. If you answer N to question one, the program asks
you to type in a list of the bad blocks. It then formats the disk except
for the bad blocks you specify. You can specify the bad blocks using the
list that comes with the drive. The program asks you for the last eight
digits of the serial number (found at the top of the disk drive). Restore
mode requires about 15 minutes.

•

Reconstruct mode. If you answer N to questions one and two, the
program searches the disk and identifies the bad blocks. It does not
use the manufacturer's bad block information. It then formats the disk
except for the identified bad blocks. Reconstruct mode requires about
30 minutes.

A.1.2 Formatter Messages
Table A-I lists the formatter messages, their probable causes, and actions
to correct the problem. The first few errors can occur almost immediately.
The remaining errors can occur from one minute to longer than ten minutes
after the program starts.
