4.47.1 Overview
The SAIC
225
Galaxy 1100 is a portable PA-RISC workstation based on the regular HP 9000/712 work-
station in a ruggedized, portable case. However it is not a notebook since it lacks a battery and needs
to be connected to standard AC power input.
The Galaxy 1100 is a very rare system, originally built for military/intelligence applications to the
following standards:
Portable requirements: Navy TAC-4
Shock: Federal Test Method Standard 101C, Method 5007.1 free-fall drop test
Airborne: MIL-STD-740-1, Grade C, Table 1
SAIC developed several special I/O devices attached to the mainboard via GIO/TSIO expansion cards.
