RP06/TE16 and RP06/TU77 Based
VAX-11/780 System Configuration

The VT52 terminal photographed with this system must be purchased separately.

Effective: April 1980

Configuration Guidelines
This VAX-111780 packaged system is configured with 1 million
bytes of ECC MOS memory, an REP06 single access 176 million
byte disk drive with MASSBUS adapter, a TEE16 (45 inches/second) or TEU77 (125 inches/second) magnetic tape transport unit with MASSBUS adapter, an LA 120 DECwriter Ill console
terminal, and a BA 11-K extension mounting box containing one
DD11-DK back panel mounting unit and one DZ11-A asynchronous multiplexer for connection of eight EIA communication lines.
Please note that there may be no substitution made for the LA 120
console terminal in this packaged system. Also note that it is not
advisable to use a video terminal as the console device because
there are cases where diagnostics and system software messages
are longer than the number of lines available on the screen. In
these cases, parts of the error messages would be lost as they
scrolled off the top of the screen.

Memory (Local and Shared)
The CPU cabinet in this system has predesignated space available for an additional 3,072K bytes of ECC MOS, 16K chip
memory for a total of four million bytes in the basic CPU cabinet.
Additional memory may be ordered in any of the combinations
noted in the VAX-111780 SYSTEMS AND OPTIONS SUMMARY.

Cabinet is required. The MA780 cabinet is always positioned adjacent to the CPU cabinet or the CPU Expansion Cabinet.

1/0 Adapters (UNIBUS and MASSBUS)
One DW780 UNIBUS Adapter (USA) and two MASSBUS adapters
(MBA) are mounted in predesignated CPU cabinet space. Additional UBAs and MBAs can be mounted in the Option Panel
Spaces available in the CPU Expansion Cabinet, H9602-HA(HB).
Each additional USA and MBA requires one Option Panel Space.
VAX-11 /780 systems can accommodate up to four UNIBUS adapters AND four MASSBUS adapters.
The system can run as many devices from a USA as will mount
into the allowable backplanes (within the power and bus load
limits of the UNIBUS) and as are supported by the VAX/VMS
operating system. One BA 11-K must be ordered for each USA
which is added to a VAX-11 /780 system, in order to mount options
which are to be connected to additional UNIBUSes.
Additional disks (RM03 and RP06) can be added to either MASSBUS on this system without expanding it to a third MASSBUS.
Likewise, additional magnetic tapes can be added to this system's
magtape MASSBUS. When application considerations dictate
more than two MASSBUSes, additional MBAs may be ordered.

For expansion beyond the four million bytes to a maximum of
eight million bytes of local memory, an H9602-HA(HB) CPU Expansion Cabinet can be ordered. An additional four million bytes
of memory with control (one MS780-C plus combinations of
MS780-D expansion memory) can be mounted in this cabinet.
The MS780-C controller requires two Option Panel Spaces in the
CPU Expansion Cabinet.

These are REM03, REP06, TEE16, TEU45, and TEU77 which include the mass storage device, its controller, a MASSBUS adapter, and its power supply.
Each MBA can run up to eight disk drives, OR eight tape drives
and seven disk drives on its MASSBUS.

Physical memory can also be expanded using the MA780 Multiport (shared) Memory Option. Two of these options can be added
to a VAX-11/780 system. Each MA780 holds up to 2 million bytes
of ECC MOS memory.
Maximum VAX-11 /780 configurations will therefore support up to
12 million bytes of ECC MOS memory.
The MA780 Multiport Memory Option is connected to a VAX11 /780 via port interfaces (MA780-C). One MA780-C can be
mounted in the basic CPU cabinet. If two MA780 subsystems are
to be connected, an Option Panel Space in the CPU Expansion

Table I lists necessary information on expansion space, plus available power and bus loads for configuring add-on equipment to
this VAX-11 /780 packaged system.

High-Performance Channel Interface
The DR780 is a general-purpose interface which can be used to
connect customer-designed devices to a VAX-11 /780. Also, two
DR780s can be used to connect two VAX-11 /780 systems.
The DR780 requires one Option Panel Space in a CPU Expansion
Cabinet, H9602-HA(HB). It includes the interface logic, power
supply and 25 ft. of cable. There is a limit of one DR780 per VAX-

ASYNCHRONOUS 8-LINE EIA MULTIPLEXER

Asynchronous Multiplexers (Programmed 1/0)
There are two kinds of asynchronous multiplexers available on
VAX-11 /780 systems, one for 20mA current loop operation and
one for EIA/CCITT. Each of these is available in 8- or 16-line units.

The table below indicates the correct options to order based upon
the number and type of terminals or lines to be used. Note that a
OZ11-A with eight EIA lines is standard with every packaged system.

Quantities of EIA lines and 20mA lines can be mixed, but only in
groups of eight on different distribution panels. The first 8 lines of
either option includes a 16-line distribution panel which is
prewired. So, for example, if 8 lines of EIA and 8 lines of 20mA are
desired, two different distribution panels are required. To expand
to more than 48 lines, an H9602-0F(OH) UNIBUS Options Cabinet
can be added.

BA11-KE (KF) EXTENSION MOUNTING BOX

The information in this table should only be used for an initial
VAX-11 /780 system.

UNIBUS Expansion Cabinet
An integral component in all VAX-11 /780 packaged systems is the
UNIBUS Expansion Cabinet which contains one BA 11-K extension mounting box, one 0011-0K backpanel mounting unit, and
one OZ11-A asynchronous multiplexer. The UNIBUS Expansion
Cabinet can house a maximum of two BA 11-K extension
mounting boxes and provides space for up to three OZ11 distribution panels. Each distribution panel is capable of handling up to
16 lines for either EIA or 20mA terminals for a possible total of 48
asynchronous lines.

Power Supplies
This VAX-11 /780 configuration includes four power supplies
which provide power for the CPU, UNIBUS Adapter, two MASSBUS adapters, optional WCS (KU780), and the first four million
bytes of ECC MOS memory.
There is predesignated space in the CPU cabinet for the power
supplies included with the Floating Point Accelerator option and
the H7112-A(B) memory battery backup option.

To expand beyond the limits of the UNIBUS Expansion Cabinet, a
UNIBUS Options Cabinet, H9602-0F(OH), can be ordered (see
back cover). This cabinet, which includes an 861-C(B) power control, provides space for two additional BA 11-K boxes and three
more OZ11 distribution panels.

The optional VAX-11 /780 CPU Expansion Cabinet, H9602HA(H B), also includes space for two power supplies to accommodate additional memory and 1/0 adapters, and for the power supply included with the optional memory battery backup.
In the RP06/TE16 or RP06/TU77 system configuration, there is a
total of 46.5 amps of power available @+5Vor 18 bus loads for
UNIBUS options expansion. (See Table I below.)

The illustration above shows where the OZ11-A and the 0011-0K
mount in the system's BA 11-K, leaving a total of 6 Hex slots and 2
Quad slots of additional mounting space.

Environmental Considerations

SPACE FOR DIST.#5

VAX-11 /780 systems, as well as other DIGIT AL products, are designed to perform while exposed to a variety of environmental
conditions. DIGITAL recommends the following environmental
operating specifications for the computer facility for maximum
reliability:
•
•
•
•

Temperature: 18°C to 24°C (65° to 75°F)
Temperature rate of change: 2°C/hr.(3.6°F/hr.).
Relative humidity: 40% to 60% (non-condensing).
Humidity rate of change: 2%/hr.

All VAX-11 /780 system environments should be fully evaluated by a
Field Service representative to ensure proper performance.

Add-On UNIBUS Options Cabinet
H9602-DF(DH)
For UNIBUS expansion beyond the limits of the system's UNIBUS expansion cabinet, the UNIBUS Options Cabinet may be ordered, H9602DF(DH). This single-width, high-boy cabinet, which includes an 861-C(B)
power control, can accept two additional extension mounting boxes
(shown in the diagram to the far right as BA 11-K #3 & BA 11-K #4), and
three more DZ11 distribution panels.
Please note that backpanel mounting units must be ordered separately
for use in this add-on UNIBUS Options Cabinet.

VAX-11 /780 CPU Expansion Cabinet
H9602-HA(HB)
A single-width, high-boy cabinet, referred to as the H9602-HA(HB) CPU
Expansion Cabinet. This cabinet includes four Option Panel Spaces
which may be used to mount additional memory, port interfaces for the
Multi port Memory option, 1/0 adapters and the DR780 interface option.
These subsystems can be configured as required up to the maximum
number of each device supported by the VAX/VMS operating system
and within the available mounting space in each system. Refer to the
VAX-111780 Systems and Options Summary for more detailed information on the mounting requirements of the various subsystems.
