SAIC Talon are portable PA-RISC workstations based on HP 9000 712 workstations in a ruggedized case released in 1994. Talon portables are almost unknown today, originally built by SAIC in the 1990s for military and intelligence applications as part of the US Navy TAC-4 program.

HP supplied the US Navy in the 1990s in the TAC-4 program with PA-RISC workstations. For severe environments, HP contracted SAIC to produce ruggedized MIL-SPEC workstations for the Navy: the SAIC Talon and Galaxy.

Both Talon and Galaxy were based on HP 9000 712 workstation design, with Talon seemingly even more ruggedized than Galaxy, painted in Forest green, color 24052 per FED-STD-595. Talon and Galaxy were produced under military contract and used in classified environments, so only few became available to civilian world. There is scant information available on SAIC Talon.

There were a few other RISC Laptops in the 1990s, with a wide variety of processor architectures such as SPARC, PowerPC and even Alpha.

  • SAIC Talon, HP 9000 712, were possibly introduced in 1994

Chipset

SAIC used the HP 9000 712 workstation design, based on the integrated HP LASI chipset, a custom and highly integrated HP design, which combines many functions and I/O on a single chip. Together with the on-CPU memory controller (MIOC), this resulted in a very integrated system architecture.

  • HP LASI integrated chipset
  • Integrated NCR 53C710 8-bit single-ended SCSI-2
  • Integrated Intel 82596CA 10 Mbit Ethernet controller
  • Integrated HP Harmony CD/DAT quality 16-bit stereo audio
  • HP Artist graphics, 8-bit, 1 MB VRAM (could be extended to 2)
  • Integrated Other I/O (serial, parallel, floppy)
  • PCMCIA controller, possibly from SAIC
  • EISA controller, possibly HP Wax
  • Optional EISA-VME bridge
  • Optional Modem via PCMCIA

HP LASI was primarily designed for cost-reduction while still providing all required I/O functions in a single chip. It was used as the main system controller in most PA-7100LC and PA-7300LC systems. SAIC added the PCMCIA, VME and EISA controller and drivers.

Display

  • 10.4″ active matrix LCD
  • 1024×768 resolution
  • full-color

Human Input

  • 85-key integrated IBM-PC keyboard with 12 function keys
  • Three-button Force pad

System buses

Expansion

Memory

  • Possibly: 72-pin ECC SIMMs, same as on standard HP 9000 712
  • 8-32 MB modules
  • Four sockets
  • 16 MB (2×8) minimum, 128 MB (4×32) maximum
  • Memory has to be installed in pairs, starting from slot 0

Expansion cards

SAIC provided a 14.4k modem for the PCMCIA slot, which are labelled optional in documentation. It is unclear what happened to the standard GSIO/TSIO slots on stock 712 mainboards. It is also unclear how the EISA expansion was added to the system, and how the VME connects to it.

  • Optional Two PCMCIA slots, for Type I/II or III
  • EISA card slot
  • Optional VME through EISA-to-VME extender

Storage

  • One 3.5″ Fast-Narrow 50-pin SCSI-2 hard drive
  • One 3.5″ 1.44 MB Floppy drive

Ports

  • SCSI-2 50-pin Fast-Narrow single-ended
  • Serial RS232C DB9 (up to 115200 baud)
  • Parallel DB25
  • Ethernet RJ45
  • Ethernet AUI 15-pin
  • VGA HD15
  • Two PS/2 connectors for keyboard & mouse
  • Three phone jacks (microphone, headphones and line-in)
  • Optional Modem

Operating systems

Talons are possibly normal PA-RISC workstations and should support standard PA-RISC operating systems and software.
