Introduction
The success of DIGITAL's products is built on the concept of architectural compatibility. One of the leading
examples of DIGITAL's superior architecture is the PDP-11. This uniquely successful computer family is based
upon a compatible set of processors, ranging from a single chip to full multipurpose computer systems. All of these
processors are built using a common hardware architecture. You can upgrade or expand any DIGITAL system by
adding memory, peripherals, or processors without introducing major incompatibilities into your system. PDP-11
minicomputers and microcomputers are engineered to provide increased functionality in smaller, more economical
packages, while still utilizing the same powerful software as their larger predecessors. Today's PDP-11 s provide a
full product range from chips to systems to networks.
Complementing these computers are a complete array of operating systems: realtime multitasking systems,
timesharing interactive multiuser systems, compact realtime single-user systems, small and midrange commercial
systems, multiuser data management systems, and a development and runtime system designed expressly for
microcomputers. With Digital's Operating System General License, you can choose the particular operating
system that best fits your application needs. Every operating system equips you with a full set of application
development tools, and every processor can support additional language compilers, networking options, and an
ever-expanding selection of application software.
The PDP-11 Systems and Options Catalog is released each quarter to provide you with the most accurate and upto-date information on currently available PDP-11 systems, options, and software products. Whether you are a
new or existing PDP-11 customer, this catalog will help you select the best Digital products to meet your
computing needs.

Introduction
How to Use This Catalog
The following Section Overview will help you find all of the appropriate product information you require, whether
you want to expand your current system, configure a new system, or perform your own integration of system
components. The catalog has been divided into nine major sections. There is also an index and appendix. Each
section begins with a product selection chart that includes page references so that you can quickly determine what
products are offered and where they can be found in that section. Configuration and site preparation charts
contain detailed technical specifications (power requirements, mounting codes, etc.) for all products, and are
located at the end of each section.
Software Ordering Information is contained at the end of the Software and Networking Sections.
Section 1 - Systems describes the PDP-11 computer models and systems, beginning with the LSI-11-Bus family
of computers-the MICRO/PDP-11, the PDP-11/23-PLUS and the PDP-11/23-S and following with the UNIBUS
family of computers- the PDP-11 124 and PDP-11 144. Each system model description includes faetures and
benefits, performance characteristics, expansion information, site preparation figures, ordering information, and a
checklist of supported options.
A diagram of the CPU box and a graphic system configurator are also included for each computer model. The CPU
box shows the location of modules bundled in the system (for example, the CPU or controller), the location of
dedicated modules (for example, memory or floating point processor) and expansion slots (for example, hex, quad,
extended LSI-11 quad or double). The system configurator is designed in the form of a worksheet to enable you to
write down the options you wish to purchase, and calculate the deduction of the DC power and bus loads drawn
by each option. (See the sample worksheet on the next page.)
If you run out of DC power in the CPU box before adding on all your options, you will need to purchase an
expansion box. Should you run out of room in the CPU cabinet for another expansion box, then it is necessary to
purchase another cabinet. These expansion products are also described in this section.
Section 2 - Options provides all the necessary information for selecting and configuring the processor, memory,
communication, and realtime 1/0 options ;rat are available for the LSI-11 or UNIBUS systems you have selected.
The new flexible option ordering plan is described in detail at the beginning of this section. Please read it over
carefully, as many of the options have new order code designations.
Section 3 - Components includes LSI-11 chip and board-level products for customers who want to perform their
own system integration. A complete selection of LSI-11 processor and memory options, enclosures, backplanes
and development tools is included.
Section 4 - Disks and Tapes describes the disk and magnetic tape subsystems available for the LSI-11 and
UNIBUS systems. Included is a description of the Digital Storage Architecture (DSA) and both the UDA50 and
RQDX1 controllers. Again, each product description includes complete performance characteristics and ordering
information.
.
Section 5 - Personal Computers describes Digital's new family of personal computers: DECmate II-tailored to
meet the needs of the small business and office environments; the Rainbow 1 OQ-designed for popular industry
standard personal computer applications, and the Professional 325 and 35Q-designed to bring minicomputer
performance and professional applications to personal computing. These product descriptions include some of the
hardware and software options available for each model. For complete information on hardware and software
options, consult the Personal Computer Summer Catalog.
Section 6 - Terminals and Printers include Digital's wide variety of video terminals, graphics terminals, hardcopy
terminals, page printer and lineprinters that are available for LSI-11 and UNIBUS systems.
Section 7 - Software describes the seven operating systems that can run on your PDP-11, plus optional
software-programming languages, information management, word processing, graphics, and application packages-you can add. License and ordering information is provided.
Section 8 - Networking provides information on Digital's network architecture and our communication software.
The communication software includes: DECnet-for Digital-to-Digital communication, either locally or remotely;
Internets-for connecting Digital systems to non-Digital systems; and Packetnet System Interfaces-for connection
of systems through a public packet-switching network.
Section 9 - Customer Services summarizes some of the excellent support services Digital offers, including Field
Service, Software Services, and Educational Services to meet your hardware, software, and training needs.
Section 10- Index will help you find the information you need quickly and easily.
Appendix A - Tables for translating the old LSI-11 Bus and UNIBUS option order codes to the new ordering
nomenclature.

Introduction

Introduction'
The following terminology is used in this catalog for configuring and ordering PDP-11 products. A sample
configurator worksheet is included to illustrate how to add options to your system and to help define the terms
used in the product descriptions and in the ordering and configuring charts.

Orderi ng Information
The model numbers are the deSignations used to order products in this catalog. For products that are voltagel
frequency dependent the designations are in the following format. The 1 20Vac/60Hz variation of the model
appears first, followed by the 240Vac/50Hz system in parentheses. For example with model number H7750BA(BD), the H7750-BA deSignates the 120 Vac, 60 Hz power model. The H7750-BD deSignates the 240 Vac,
50 Hz power option.
Communications and liD options have new order code deSignations which indicate whether the options are
puchased with a new system or added to an existing system. The following terms describe this flexible option
ordering plan:
System option

Ordered with CPU. Includes the generic option and all the appropriate cabling, I/O connection panel
inserts and bracket hardware for installation on that CPU. Example: OMR11-AP.

Base option

Board or peripheral without cables. Example: OZV11-M

Cabinet kit

Unique cable, I/O connection panel insert and bracket hardware required to install the option in a specific
cabinet or enclosure. Example: CK-OZV11-0B

External cable

Shielded cable which connects peripherals to the enclosure. These cables must be ordered separately
for communication options. The -xx designation in cable model numbers indicates that different length
cables or other product variations are available and that the order code corresponding to the desired
option must be specified. (See Price liSt.)

See Appendix A for conversion of the old option order codes to the new nomenclature.

Configuring Information
There are five factors to consider when you configure PDP-11 systems:
• Expansion Space - the space in a CPU or expansion box to accommodate a specific type of backplane or
module. Expansion space refers to phYSical space,for example, SU(s) or Quad Slots. (See CPU Backplane
Diagram below.)
• Power Requirements-the amount of DC current and watts each option requires. The figures for available
power are supplied in the configurator worksheet.
• Bus Loads-the number of AC and DC busloads drawn by each option. The figures for available bus loads are
supplied in the configurator worksheet.
• Priority-the order in which options are placed in the backplane can affect system performance. For example,
the UDA50 disk storage subsystem control unit is always configured as the last device on the UNIBUS
backplane. Note: Each system will be integrated with all modules in the correct prioritized order (not
necessarily the order shown in the sample configurator).
• liD Connection Panel Insert Space-space in the liD Connection panel (located at the back of the system
box) used to carry connectors for communications and peripheral devices. Options vary in the number of
connection panel units of space they require. The number of available insert spaces is included in the
configurator worksheet.
Once you have selected those options that meet your system requirements, list them in the option column of
the configurator, refer to the option chart that lists the power and space requirements mentioned above, and
begin subtracting the figures given for each option from the figures provided with the system configuration.

vi Introduction

New Cabinet and Cabling
Digital has implemented a design for shielding cabinet and cabling to reduce the potential of electromagnetic
interference from computer devices. This new cabling system is made up of three parts:
• First, a shielded CPU enclosure and an internal cable that originates at the option module or controller
• Second, a shielded I/O Connection Panel that jOins the internal and external cables and provides the transition
between option modules and externally connected devices.
• Third, an external cable that attaches to the peripherals

The I/O Connection Panel (described in Section 1- Systems) completes the shielding envelope and provides the
filtering necessary to contain potential radio frequency interference within the cabinet. All cables entering or exiting
the cabinet must do so via the I/O connector panel.
To simplify the task of connecting Digital and Non-Digital devices to systems in the same way, a wide range of I/O.
connector panel hardware is offered through the Installed Base Marketing Group.

1 Systems
Digital's PDP-11 systems are based on a compatible set of processors, all using a common architecture and a
common instruction set, and all capable of supporting any of seven PDP-11 operating systems. PDP-11 systems
offer the widest selection of operating systems, languages, data management, communications and applications
software in the industry. With over 300,000 systems installed worldwide, the PDP-11 is the most popular
minicomputer in history. PDP-11 s can also be easily connected to our larger VAX systems, to personal computers,
even to other vendors' mainframes, and into an Ethernet.
Using this section in conjunction with the Software section of this catalog it is easy to find the combination of
hardware and software that will meet your exact requirements. The system selection chart on the facing page can
be used for a quick comparison of PDP-11 systems.
The system section is divided into two parts : LSI-11 Bus systems and UNIBUS systems. The two bus
implementations provide similar I/O speed and memory addressability. The major difference between the two lies in
the type and variety of peripheral devices which can be added to the system.
The LSI-11 Bus was introduced in 1975. Its simple design permits the implementation of very small, inexpensive
computer systems, such as the MICRO/PDP-11 and the PDP-11/23-PLUS. The largest Digital disks these two
systems support have a 10MB capacity per drive. The fastest networking interface runs at 56K bits per second.
The current generation of LSI-11 bus microcomputers is capable of supporting 4 to 1 2 concurrent users, depending
upon the application.

Systems
The UNIBUS, the original PDP-11 bus, was introduced in 1970. Applications that require high-speed communications or large disk capacity (up to 400 MB per drive) are typically based on UNIBUS PDP-11 systems, such as the
PDP-11/24 and PDP-11/44. (Many UNIBUS peripherals are also supported on Digital's VAX-11 family of 32 bit
superminicomputers.) The PDP-11 /44 can support up to 48 concurrent users.
All PDP-11 packaged systems include, as minimum components, a CPU·, memory, console terminal interface, and a
disk subsystem. Most include the PDP-11 Operating System General License which allows you to run any or all
PDP-11 operating systems on your computer. Software media, documentation and support services for each
operating system may be ordered as needed. Refer to the Operating System Ordering Chart (page 7-13) in the
Software Section of this catalog. None of these systems include a console terminal. You can select the terminal that
best suits your application from the wide variety of video and hardcopy models described in the Terminals &
Printers section of this catalog (page 6-1 ).

The LSI-ll Bus Family of Multiuser Systems

The LS1-11 family includes not only the base and packaged systems described here, but a range of chips, singleboard computers, and components which are more fully described in the Components section.
Two LS1-11 multiuser systems are offered: the PDP-11 123 PLUS and the MICRO/PDP-11 . Because they.utilize
the same PDP-11 123-PLUS CPU, they have many features in common. They execute an identical instruction set,
support many of the same devices, and support the same memory and performance enhancement options.
The MICRO/PDP-11 is designed for small, multi-user applications where size and cost are of paramount concern.
The PDP-11 123-PLUSis more expandable and can handle a wider range of concurrent functions, more
communications, and more mass storage. For the lowest priced PDP-11 123-PLUS CPU package, there is the
PDP-11 123-S which offers the performance of a PDP-11 in a 3.5 inch rack-mountable box.

LSI-11 Computer Features:
• Physical memory addressing up to 4 MB (backplane space permitting) for improved performance in multiuser
applications.
• Optional non-volatile CMOS memory for use in environments where power conditions are uncertain .
• Two asynchronous EINCCITT interfaces: one for the console terminal and one for expansion.
• Parity MOS memory expansion in 256 KB or 512 KB increments.
• Optional Commercial Instruction Set chip for faster PDP-11 COBOL-81 program execution.
• Optional floating point instruction chip or a floating point processor board for faster BASIC and FORTRAN
program execution.
• Two CPU operating modes: Kernel and User .
• Diagnostic bootstrap which tests memory, CPU, and the console terminal on startup, then boots the system
from a designated disk or DECnet line.
• I/O Connection Panel to simplify cable management.

MICROjPDP-ll

The MICRO/PDP-11 family of small, multiuser computers consists of both floppy-disk and fixed-plus-floppy
systems. They are packaged to fit easily under a desk or worktable, on a tabletop, or as a rack mountable box
enclosure, and can be expanded to support up to 10 users.
The 5.25 inch RD51 Winchester disk drive, included in some MICRO/PDP-11 models, has a formatted capacity
of 10MB. The RX50 floppy diskette subsystem, included in all models, accepts two single-sided 5.25 in
diskettes, each with a capacity of 400KB. (These are the same diskettes used by Digital's Professional series of
personal computers, described in the Personal Computers Section in this catalog.) The RQDX1 controller
handles both the RD51 and the RX50 and performs Direct Memory Access (OMA) block-mode transfers for
maximum system efficiency.
The major sub-assemblies -floppy subsystem, system enclosure, processor and memory - are available in
component form for system integrators and OEMs.
To facilitate international distribution, 15 country kits are offered. A country kit includes a user-friendly checkout
diskette, miscellaneous labels and hardware, and a 25-foot null modem cable. Order a country kit in the specified
language from the LSI-11 options checklist on the previous page. All systems may be set for either 1 20V or
220/240Voperation.

Ali Multiuser MICRO/PDP-11 s include the standard LSI-11 computer features plus:
• 256 KB parity MOS memory expandable up to
4 MB, backplane space permitting
• One 5.25 inch dual 400 KB RX50 diskette subsystem

Configuring MICRO/PDP-11 Multiuser Systems
In addition to the routine factors of option power requirements and available backplane slots, the utilization of the
, I/O Connection panel must be considered.

Power Requirements and Bus Loads
Each MICRO/PDP-11 option requires a certain amount of DC current and AC and DC bus loads. To configure a
system, subtract the power requirements and bus loads of the options from the available amps at + 5V and at
+ 1 2V and the available AC and DC bus loads. (The figures for available power and bus loads are supplied in the
configurator worksheet.)

Backplane Slots
The MICRO/PDP-11 has the first three slots configured to accept one option each (quad or dual). The next five
slots can accept one quad option or two dual options. When configuring options, make sure that Dual width
options get placed adjacent to one another to make efficient use of slot space. If for priority reasons you have a
Dual option, followed by a Quad option, a bus grant continuity card (G7272) is included in your country kit to run
signals to the Quad option. Consult the Micro/PDP-11 Handbook for more information on priority schemes.

1/0 Connection Panel Insert Space
The I/O Connection Panel for the MICRO/PDP-11 is a 1 2 in x 5 in plate located at the back of the system box. It
is used to carry connectors for communication cables. These cables connect the computer to terminals and
mass storage devices outside of the chas~is. The panel is designed to simplify cable management.
MICRO/PDP-11 options have panel inserts which come in two sizes: size A (1 in x 4 in) and size 8 (2.6 in x 3.2
in). The panel has space for two A inserts and four 8 inserts. An adapter plate is included for converting two 8
inserts to three A inserts. The MICRO/PDP-11 options consist of two distinct parts: 1) the module, for example
the DZV11, 2) the cabinet kit, conSisting of one size 8 panel insert with 4 EIA connectors, and the cable to
connect the module to the panel insert. Mounting hardware is also included.

Refer to the Option Configuring Charts at the end of Section 2 and at the end of the Disks and Tapes Section
for the power reqUirements, bus loads, backplane and I/O Connection panel insert sizes for each option.

CPU Cabinet Expansion
There is a 5.25 in high (13.2 cm) by 26.8 in deep (68 cm) area of mounting space available below the CPU box
for expansion. This is typically used for a BA 11-SE(SF) 8-slot expansion box to accommodate additional
communication or realtime options.
The BA 11-SE(SF) is a cabinet-mountable expansion box with bezel required for 22-bit expansion of the PDP-11 I
23-PLUS system. System expansion is limited to a single BA11-SE(SF). It must be mounted in the CPU cabinet.
When purchasing the BA 11-SE(SF) expansion box with a system, the 1 20V version will contain the 87 4-C
power controller. Customers planning to field install the 1 20V expansion box in the CPU cabinet are required to
purchase a replacement power controller (874-C or 874-D). When the BA11-SE(SF) box is ordered with the
system, Digital supplies the appropriate power controller at no extra cost.
Note: Cable not included. Order the BCV2A-03 Extended LSI-11 BUS cable and expansion assembly for
connecting the CPU box to the expansion box.

1/0 Connection Panel (H349)
The I/O Connection Panel for the PDP-11 123-PLUS is an 11.5 in (28.32 cm) by 18 in (44.10 cm) plate located
at the back of the system box. It is used to carry connectors for cables. These cables connect the computer to
terminals and mass storage devices outside the CPU box. The panel is designed to simplify cable management.
PDP-11 123-PLUS options have panel inserts which come in two sizes: size A (1 in x 4 in) and size C (4 in x 4 in).
The panel has space for nine size A inserts (J1 ,-2,-3,-4,-5,-8,-9,-10,-11) and four size C inserts (J12,-13,-14,15). The two connectors labelled J6 and J7 are for the two serial lines provided with every system. An adapter
plate is also included to convert four size A inserts (J8-J 11) to one size C insert. The PDP-11 123-PLUS options
consist of two distinct parts: 1) the module, for example the DZV11, 2) the cabinet kit, consisting of the panel
insert, in this case one size 8 with 4 EIA connectors, and the cable to connect the module to the panel insert.
Mounting hardware is also included. (See diagram below.) The Configuring worksheet has space provided for
figuring available panel insert space.
For ease in ordering options, adapters are included with cabinet kits to enable mounting size 8 (2.6 in x 3.2 in) in

The PDP-ll UNIBUS Family of Computers

Today Digital offers two computer models based on its highly successful UNIBUS technology. They are the PDP11/24 and the PDP-11 144. Together these products provide a wide range of minicomputer solutions from small
dedicated control, communication, and computational applications, to larger, multi-user business and scientific
timesharing systems. They share a common backbone--the UNIBUS. This bidirectional asynchronous interconnect
links these versatile processors with the industry's most comprehensive set of mass storage systems and
communications interfaces. It provides the configuration flexibility and growth capacity that make these processors
ideal solutions for a broad spectrum of applications.
The PDP-11/24 and the PDP-11/44 execute a common instruction set, run under the control of any of Digital's
PDP-11 operating systems, and make available the problem solving power of Digital's proven languages, data
management, communications and networking products.
Both the PDP-11 124 and the PDP-11 144:
• Provide high performance Floating Point and Commercial Instruction Set processor options
• Offer memory expansion up to 4MB for enhanced multi-user and realtime performance
• Permit memory expansion in 1 MB increments
• Support the microprocessor-based DSA (Digital Storage Architecture) for high density mass storage and
reduced CPU overhead
• Support the microprocessor-based network communications options for comprehensive system configuration
and resource sharing
• Offer enhanced system reliability and availability through self-diagnostics and power monitoring, and optional
battery backup and auto restart
• Include ASCII console logic for system control/debugging with optional console terminal
• Include two EINCCllT serial interfaces, one for the console terminal and one for expansion
• Provide compatibility with existing UNIBUS peripheral devices for smooth system upgrades
• Offer unmatched configuration flexibility and system growth capacity
The PDP-11 /24 was designed to provide the basis for compact, low cost application solutions. Its features include
a single board CPU with space for optional Commercial Instruction Set and floating pOint processor chips. It offers
an optional hardware Floating Point Processor that delivers up to 6 times the performance of the FPP chip. The
PDP-11/24 provides sophisticated memory management coupled with the extended memory addressing option,
the KT24, that provides 4 MB memory addressing. These features combine to give the PDP-11 124 capabilities
that were previously only available on larger, more powerful PDP-11 s.

1 -1 8

Systems

UNIBUS Family of Computers
The PDP-11 144 was designed to provide a higher level of performance and greater total system capacity, at a
moderate price. It delivers roughly twice the performance of the PDP-11 124, and it is ideally suited for larger,
multi-user departmental level applications. The PDP-11 144's unique features include an 8 KB high speed cache
memory, standard 22-bit extended memory addressing, separate Instruction and Data address space support with
additional general registers, and three operating modes. In addition, the PDP-11/44 offers high performance
hardware Commercial Instruction Set and floating point processor options. The PDP-11 144 provides the kind of
configuration flexibility and growth capacity that is characteristic of all PDP-11 s.
The PDP-11 124 and PDP-11 144 are available in four levels of integration:
• The Rack-mountable Computers provide significant expansion space and memory expansion up to a maximum
of 4 MB.
• The cabinet-mounted Kernel Computers provide a base for OEM system integration.
• The System Building Blocks allow the choice of system and load devices from a variety of disk and tape
subsystems and include the PDP-11 Operating System General License.
• The Packaged Systems include all the necessary hardware and software components (with the exception of

Power Controller

The shielded UNIBUS I/O Connection Panel, located at the back of the CPU cabinet, is comprised of two or more
interlocking frames, option panel inserts and blank inserts that are used to maintain shielding continuity. The I/O
connection panel is bolted horizontally on the back lowest section of the H9642 cabinet and is bolted vertically on
the left rear of the H9645 wide cabinet.
Depending on the system configuration, there are several combinations of option panel inserts and blanks within
the frames. In the example above, the upper right option connector insert can accomodate multiple devices such
as EIA terminals. The lower right insert is the power controller. It is always mounted in this location and is an
integral part of the shielded panel.
As the diagram illustrates, the panel inserts come in a variety of sizes depending on the particular option that is
installed in the system. These insert sizes must be considered when adding options to a system. All device and
communication cables must exit or enter the cabinet via the I/O connector panel to maintain the integrity of the
shield. The UNIBUS I/O connection panel has space available for twelve panel inserts units. Refer to the UNIBUS
Options Configuring Charts at the end of Section 2 for the correct panel insert sizes for each option.

Cabinets

UNIBUS CPU Cabinets
Two CPU cabinets are available for integrating the PDP-11/24 and PDP-11/44 CPU boxes with Digital mass
storage devices or non-Digital mounting boxes. These cabinets feature a centered, shielded enclosure and
shielded cable duct which is routed to an 1/0 Connection panel. When mounted in this shield, and used with
appropriate interfaces and 1/0 connection panel inserts, the PDP-11/24 and PDP-11/44 comply with FCC RF
emission regulations as Class A systems. The top and bottom mounting spaces are not shielded, and only Class A
compliant equipment should be mounted in them. Digital Disk subsystems are RF shielded at the box level, and
may be mounted in these spaces. Note: Because of its depth, the RA60 disk subsystem cannot be mounted in this
cabinet. It requires its own deep H9642-AP(AR) cabinet. BA 11 expander boxes cannot be mounted in the CPU
cab.
The CPU cabinets are supplied with power controllers capable of furnishing 24 amps of 1 20V AC or 1 2 amps of
240VAC.

Ordering Information:
H9642-EA(EB)

CPU cabinet includes mounting space for a 10.5 inch or 5.25 inch CPU, one additional 10.5 inch 01'
5.25 inch device, and a ba~ery backup unit. The I/O connector panel is included.

H9645-EA(EB)

Wide CPU cabinet provides mounting space for a 10.5 inch CPU and two additional 1 0.5 inch or 5.25
inch devices. Side mounting space is provided for the battery backup unit. The I/O panel is included.
Because of AC power constraints, only one RA80 or RA81 disk subsystem may be mounted in this
cabinet. The Digital disk subsystems which may be mounted in these cabinets include the RUA80AA(AD), RUA81-AA(AD), RL211-AK, TU58-DA, and the RX211-BK(BN).

UNIBUS Expander Cabinets
Expander cabinets are furnished without side panels. They are bolted to the right end of H9642 or H9645 CPU
cabinets. The existing right side panel of the CPU cabinet is then used as the right side panel of the expander
cabinet. A UNIBUS cable passes through a shielded port between the cabinets. I/O connection panel inserts for
all options must be located in the I/O connection panel which contains the associated device controller interface.
Expander cabinets are supplied with power controllers capable of furnishing 24 amps of 1 20V AC or 1 2 amps of
240VAC.

UNIBUS Expander Cabinets
Ordering Information:

New Option Ordering Information
Flexible Ordering Plan for Communication and I/O Options
Options can be ordered when a system is purchased- System Options, or as upgrades to a system already
installed in the field-Upgrade Options. System options are installed in a system at the factory, and upgrade
options are installed in the field. Upgrade options will be available for use with both old style-unshielded cabinets,
and with the new style-shielded cabinets designed to reduce potential EMI/RFI emissions.
The following section outlines this new ordering scheme for all LSI-11 Bus and UNIBUS communications and I/O
options. ( Order codes for processor and memory options will not be affected.)

System Options
To order the system version of an option, you need only specify a single option name on an order for a CPU. You
will receive the option, with all appropriate cabling and bracket hardware, already installed on that CPU.
Example: (Communications options)

If you want a DECnet RS232-C interface for a PDP-11 144 , you would order a DMR11-AP.

New Option Ordering Information
Upgrade Options
To purchase an option as a field add-on to an existing system, you order the base option module together with the
specific cabinet kit required to install the module on your CPU. A cabinet kit contains the unique cable, filter
assembly, and any bracket hardware required to install the option in a specific cabinet or enclosure.
For mounting options in different cabinets, various length internal cables and mounting brackets will be required on
different CPUs. Therefore, several different cabinet kits are available for one option.
UNIBUS options can be mounted in older, unshielded cabinets by ordering the cabinet kit that includes an adapter
bracket. To determine whether your cabinet is shielded or unshielded, examine the back of the cabinet. A shielded
cabinet will have metal panels with 110 connection panel inserts or blank metal plates mounted in the cutouts in
these panels. An unshielded cabinet may have devices mounted in the back of the cabinet, but will not have
complete coverage across the entire cabinet. The CPU box and disk enclosures are visible from the back of an
unshielded cabinet.
The cabinet kits available for each option are described in Section 2-0ptions.

Example (Communications Options)
If you want to add a 4·line EIA multiplexer to an existing MICRO/PDP-11, you would order the following two
options:

DZV11-M = Base option
CK-DZV11-DB = Cabinet kit to install a DZV11 on a
MICRO/PDP-11
Example: (Non-communications Options)
If you want to add a 64-line parallel interface to an existing PDP-11/23-PLUS, you would order the following two
options:

DRV11-J = Base option module
CK-DRV1 J-KC = Cabinet kit to install a DRV11-J on a
PDP-11/23-PLUS.

To summarize, LSI·11 Bus and UNIBUS communication and 110 options can now be ordered either as systemintegrated or field upgrade options. The order codes have been changed to reflect this new style of purchasing an
option specifically designed to fit any PDP-11 processor in any enclosure you now own or plan to purchase.
An appendix has been added at the end of this catalog which translates the old option order codes to the new
system-integrated and field-upgrade option order codes.

UNIBUS Communication Options
Auxiliary Communications Microprocessors
KMS11-BD

The KMS11-BD is used in a communications environment as a high speed, intelligent front-end processor
which offloads the host CPU of communication functions. Through the use of direct memory access, the
KMS11 efficiently multiplexes as many as 8 synchronous communications lines into the processor. The
KMS11 offers bit or byte oriented operation in either full or half-duplex mode. The hardware calculates
CRC-16 when using byte protocols, and CRC/CCITf, when using bit protocols. Data transmission and
rec~ption is fully controlled by the micro-processor part of KMS 11 , thus allowing full level 2 offloading for
higher processor efficiency. The micro-processor is controlled by a 4 K word memory (writeable control
store) which is loaded at system initialization time with the appropriate micro-program. Current applications utilize the Digital PSI package and a full X.25 link level package. A software tools package is
available for users to create their own custom micro-code for custom networking applications. The
KMS11 interfaces to RS232-C and MIL-188-144 unbalanced. Line speeds are dependent on the
software application. Using Digital PSI software-2 lines at 9600 b; using X.25 link level software-4
lines at 56 Kband"8 lines at 19.2 Kb. Includes a DD11-DK double system unit and all internal cables.
External cables are not included.

Terminal Concentrator
DZS11-EA/VT1 XXEB

The DZS11-EA and VT1 XX-EB, together, comprise the DECmux Terminal Concentrator. DECmux is a
statistical multiplexer that connects up to eight asynchronous terminals to a PDP-11 via a single
synchronous, full-duplex communication link. The eight terminals can be configured in one cluster, or split
into two clusters using the route-through capability. Both the main and route-through links can be made
using dedicated lines and modems or by means of DECmux's RS422 long line capability. The main and
route-though links do not have to be made the same way. All the terminals in the DECmux network can
operate at speeds of 9600 baud. DECmux is DZ11 compatible, therfore it interfaces to the operating
system using the standard device drivers. Note: If you have a second cluster of terminals, order 2
VT1 XX-EBs. External cables not included.
