Dual RK07 Disk-Based
VAX-11/780 System Configuration

Effective: January 1981

Configuration Guidelines
This VAX-11/780 packaged system Is configured with 512K bytes
of ECC MOS memory, an RK711 UNIBUS control[er with two top
loading RK07 cartridge disk drives for a total of 56 megabytes of
on-line storage, and an LA 120 DECwriter Ill console terminal.

UNIBUS

....

The CPU cabinet in this system houses a UNIBUS Mounting
Frame which contains the RK711 controller, one DZ11-A asynchronous multiplexer for connection of eight EIA communication
lines, and mounting space for UNIBUS options.

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
The CPU cabinet in this system has predesignated space available for an additional 3,584K bytes of ECC MOS, 16K chip memory for a total of four megabytes in the basic CPU cabinet. Additional memory may be ordered in any of the combinations noted in
the VAX SYSTEMS AND OPTIONS SUMMARY.

UNIBUS MOUNTING FRAME

UNIBUS expansion in this system is also governed by several
other configuring considerations:

UNIBUS Expansion
One DW780 UNIBUS Adapter (UBA) Is mounted in predesignated
CPU cabinet space. The system can run as many UNIBUS options
(listed in the VAX Systems & Options Summary) from the UBA as
will mount into the available backplane space in the UNIBUS
Mounting Frame (see diagram and Table I), within the power and
bus load limits of the UNIBUS.

First, there is a system limit of one distribution panel. The DZ11-A
which comes with this system includes a controller for eight asynchronous EIA lines and a 16-line distribution panel (to which one
DZ11-B may be added for control of an additional eight EIA lines).
Therefore, any additional distribution panels (e.g., for the DMR11,
DZ11, CS11, LPA11-K and lab options, CS11) require the add-on
UNIBUS Options Cabinet, H9602-DF(DH), for mounting.

To expand beyond the limifs of the UNIBUS Mounting Frame, an
UNIBUS Options Cabinet, H9602-DF(DH), 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 DZ11 distribution panels.

Second, expansion is limited by space available In the UNIBUS

1/0 Panel (see diagram). This panel serves as the connection
point between control modules mounted in the UNIBUS Mounting
Frame and their associated external devices.

Please note that the Information below describes the
configuration of the SV-AXHHV packaged system when It Is
upgraded with the VAX-11/780 System Upgrade Option, H9604BA(BB).

VAX-11/780 System Upgrade Option, H9604-BA(BB)

1/0 Adapters (UNIBUS and MASSBUS)

A field installed System Upgrade Option is available for this VAX11/780 packaged system. It includes one H9602-DF(DH) UNIBUS
Expansion Cabinet with power control, plus a BA 11-KE(KF) expansion mounting box and one 0011-DK expansion backplane.
The upgrade involves the transfer of all UNIBUS options in the
CPU Cabinet's UNIBUS Mounting Frame to the UNIBUS Expansion Cabinet.

One DW780 UNIBUS Adapter (UBA) Is mounted in predesignated
CPU cabinet space. MASSBUS Adapters (MBA) and additional
UNIBUS Adapters can be mounted In the Option Panel Spaces
available in the CPU Cabinet and the CPU Expansion Cabinet,
H9602-HA/HB. Each MBA and each additional UBA requires one
Option Panel Space. VAX-111780 systems can accommodate up
to four UNIBUS Adapters AND four MASSBUS Adapters.

The space occupied by the UNIBUS Mounting Frame is converted
to two Option Panel Spaces and the UNIBUS 1/0 Panel is eliminated. In addition, it becomes possible to order the CPU Expansion
Cabinet, H9602-HA(HB), which provides four additional Option
Panel Spaces.
Once the system has been upgraded, the Option Panel Spaces in
the CPU Cabinet and the CPU Expansion Cabinet can be used to
mount MASSBUS Adapters (MBA), additional UNIBUS Adapters
(UBA), a second memory controller (CPU Expansion Cabinet only), Multiport Memory port interfaces, and/or the DR780 general
purpose interface.

Memory (Local and Shared)

The system can run as many UNIBUS options (listed in the VAX
Systems & Options Summary) from a UBA as will mount into the
allowable backplanes (within the the power and bus load limits of
the UNIBUS). One BA11-K expansion box must be ordered for
each UBA which is added to a VAX-11/780 system, in order to
mount options which are to be connected to additional UNIBUSes.
An MBA is needed when adding high-performance MASSBUS
devices such as RM80, RM05, RM03, RP06, TE16, TU45, or TU77.
These devices should be ordered as REM80, REMOS, REM03,
REP06, TEE16, TEU45, or TEU77 respectively, each of which includes the mass storage unit, its controller, a MASSBUS Adapter,
and the power su
r that MBA.

For expansion beyond four megabytes to a maximum of eight
megabytes of local memory, an H9602-HA(HB) CPU Expansion
Cabinet can be ordered. An additional four megabytes 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 (OPS) in the CPU Expansion Cabinet.

Each MBA can run up to eight disk drives, OR eight TE16 or TU45
tape drives and seven disk drives OR four TU77 tape drives and
seven disk drives on its MASSBUS.

Physical memory can also be expanded using the MA 780 Multiport (shared) Memory Option. Two of these options can be added
to a VAX-11/780 system. Each MA780 holds up to 2 megabytes of
ECC MOS memory.

The DR780 is a general-purpose interface which can be used to
connect customer-designed devices to a V AX-111780. Also, two
DR780s can be used to connect two VAX-111780 systems.

Maximum VAX-11 /780 configurations will therefore support up to
12 megabytes 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 cabinet or the
CPU Expansion Cabinet is required. The MA780 cabinet is always
positioned adjacent to either the CPU cabinet or the CPU Expansion Cabinet.

DR780 High-Performance Channel Interface

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 perVAX111780 system and the DR780 cannot be configured on systems
which already include the MA780 Multlport Memory. The cable
from the user device to the DR780 can be up to 80 ft. in length.
Table II lists necessary information on expansion space, plus
available power and bus loads for configuring add-on equipment
to this upgraded VAX-111780 packaged system.

The table indicates the correct options to order based upon the
number and type of terminals or lines to be used. Note that a
OZ11-A, which includes a controller for eight EIA lines and a 16line distribution panel, 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 its own 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.
