The SAIC Galaxy 1100 were portable PA-RISC workstations based on the HP 9000/712 workstation in a ruggedized case released in 1994. They are not notebooks in the current sense but portable workstations — no battery but standard AC power.


The Galaxy 1100 portables are very rare, originally built in the 90s for military and intelligence applications. Since the Galaxy 1100 are technically normal PA-RISC workstations they support standard PA-RISC operating systems and software. The Galaxy 1000 were the 60 MHz version, the Galaxy 1100 was 80 MHz.

HP was part of the US Navy TAC-4 program in the 1990s through which HP supplied PA-RISC workstations to the US Navy for measurement and control. For environments where standard workstations were not robust enough, HP contracted SAIC to produce a ruggedized MIL-SPEC portable workstation for the Navy: the SAIC Galaxy 1100 based on the HP 9000 712.

SAIC developed several specialized I/O devices for the Galaxy that attached to GIO/TSIO expansion slots. Industry-standard PCMCIA slots were available as well through a SAIC-specific extension board. As these systems were produced under a military contract and sometimes used in classified environment only few became available to civilian world. Only two other portable PA-RISC computers were sold – the RDI PrecisionBook, based on HP Visualize C132L, and the Japanese Hitachi 3050RX/100C; the SAIC Galaxy was not directly sold outside of military contracts and only later became available publically through resellers.

A long article on SAIC Galaxy 1100 and their VUE environment by Cameron Kaiser from 2023 expands on the background and historic usage of Galaxy computers and some technicals.
