For safety information see the owner’s guide that came with the system in
which you are installing your Model 743 board computer.

Regulatory Statements

Emissions Regulations
Federal Communications Commission (FCC) This equipment has

been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules and interference causing reg­ulations of Industry Canada. These limits are designed to provide reason­able protection against harmful interference in a non-residential
installation. This equipment generates, uses, and can radiate radio fre­quency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
Howe ver, there is no guarantee that interference will not occur in a partic­ular installation. If this equipment does cause harmful interference to
radio or television reception (determined by turning the equipment off
and on), you can correct the interference by one or more of the following
measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment to an outlet on a circuit different from that to which the
receiver is connected.

Hewlett-Packard’s system certification tests were conducted with HP-sup­ported peripheral devices and HP shielded cables, such as those you
receive with your computer. Changes or modifications not expressly
approved by Hewlett-Packard could void the user’s authority to operate
the equipment.

Electrostatic Discharge (ESD) Precautions

Electrostatic Discharge (ESD) Precautions

Electrostatic charges can damage the integrated circuits on printed circuit
boards. To prevent such damage from occurring, observe the following
precautions during board unpacking, installation, and configuration:

• Stand on a static-free mat.

• Wear a static strap to ensure that any accumulated electrostatic charge
is discharged from your body to ground.

• Connect all equipment together, including the static-free mat, static
strap, routing nodes, and peripheral units.

• Keep uninstalled printed circuit boards in their protective antistatic
bags.

• Handle printed circuit boards by their edges, once you have removed
them from their protective antistatic bags.

features:

• Model type:
Model 743i/64

Model 743rt/64
Model 743i/100
Model 743rt/100

• VME slot configuration
Single slot

Dual slot (requires PCI Mezzanine Card (PMC) bridge board,
General System Connect (GSC) expansion kit or HCRX graph­ics board
Three slot (requires PMC bridge and expansion boards or GSC
expansion kit with ATM card)

• CPU PA-RISC PA7100-LC, processor performance
64 or 100 MHz

Cache - 256 KB

• Clocks

Interval timers (One 32 bit, Two 16 bit)
Watchdog timer

• Operating systems
HP-UX 9.05 (or later; some options require later releases). The

Model 743 typically boots from a hard disk drive. HP-UX may
also be installed from an external DDS or CD-ROM drive.

1-2

If the Model 743 is a client on a LAN, HP-UX can be booted
over the LAN.

HP-RT 2.0 and later.

• User interface
CDE or HP VUE graphical user interface (HP-UX only)

• Compatibility
Source and binary code compatible with Series 700 product

family.

used.

1-3

Product Information

Product Description

NOTE: Either a GSC expansion kit or the HCRX expansion graphics

boards extend graphics capability beyond the onboard graphics
chip set of a Model 743 board computer. However, the HP-RT
operating system supports only one graphics display, and HP-UX

10.x supports up to three graphics displays.

• Main Memory
Single VME slot 743i: 16 to 128 MB RAM

Single VME slot 743rt: 8 to 128 MB RAM
Dual VME slot 743i: 16 to 256 MB RAM
Dual VME slot 743rt: 8 to 256 MB RAM
(Dual slot means an expansion kit or HCRX board must be
installed.)

NOTE: A Model 743 configured for more than two RAM cards (one in

each RAM stack) requires installation of an expansion kit or an
HCRX graphics board and occupies two VME slots.

Up to four RAM cards may be installed - three cards in RAM
stack 1, one card in RAM stack 2.
RAM cards may be placed in any order. A higher capacity mem­ory card can be added on top of a lower capacity card or you can
reverse the order, with a lower capacity card on top of a higher
capacity card.

Internal SCSI-2 single-ended bus

2 asynchronous RS-232-C ports (requires a conversion cable)
1 HP parallel port (requires a conversion cable)
1 LAN AUI port (requires a conversion cable)
2 mini-DIN PS/2 ports
1 slot for RAM memory (memory cards can be stacked)
CD-quality audio, supported only by HP-UX and requires a

conversion cable

PCMCIA adapter, supported only by HP-RT

• Dual Slot Upgrades
PMC bridge board (with two PMC sites, cannot be used w/

1-4

HCRX, and supported only on HP-UX)
GSC expansion kit (with two GSC sites)
HCRX8 graphics board (with one additional GSC site)
HCRX24 graphics board (with one additional GSC site)
GSC HP A4267A graphics card
FWD SCSI card

• 3-slot Upgrade
PMC expansion board (with two PMC sites, requires PMC

bridge)
ATM Network Card (up to 2, GSC expansion kit required, can­not be used with HCRX graphics)

• Other Supported Configurations
