Hitachi 3050RX 100C are Japanese RISC laptops for Unix computing, introduced in 1994. Hitachi was a PRO consortium member for HP PA-RISC computers; the 3050RX line used stock PA-RISC processors but also some custom Hitachi designs. The 100C was based on such a custom Hitachi PA/50L processor.

Hitachi 3050RX 100C are possibly compatible with HP 9000 PA-RISC workstations but used custom Hitachi HI-UX/WE2 Unix, a modified HP-UX, apparently used for multi-media processing of the 1990s. It is unclear if the 100C was a laptop with battery or portable computer with AC (60W).

Hitachi 3050RX 100C are RISC laptops designed for Unix with Hitachi’s custom HP-UX Unix implementation HI-UX/WE2. There were two other PA-RISC laptops in the 1990s, SAIC Galaxy portable and Tadpole PrecisionBook, both for HP-UX.

Hitachi PA/50L are custom Hitachi PA-RISC low-cost processors, which Hitachi used apparently only in two computers in the 1990s. Not much further technical information is available for Hitachi 3050RX 100C Laptops.
