FACOM 9450 Personal Computer

The FACOM 9450 is a personal computer announced by Fujitsu in October 1981. Its multi-job execution capability enabled simultaneous handling of office tasks and host computer connectivity.

In 1980, Fujitsu developed the "HIT-80" with the cooperation of PANAFACOM (now PFU), enabling both office work at retail locations and immediate order placement into production processes. The FACOM 9450 integrated OA tools, Japanese word processing capabilities, and terminal functions into the HIT-80. It was introduced to the market as a "truly business-useful PC" capable of nationwide maintenance, enabling a single unit to support diverse business tasks.

It featured a proprietary 16-bit CPU and 128KB of memory with RAS functionality. Its OS was APCSII, characterized by multi-job capability (simultaneous execution of two programs) and multi-tasking capability (parallel processing of 256 programs).

Success was also driven by strong support for application package development by software development partner companies, resulting in a wide variety and large number of available packages.

The 9450 series continued enhancements until the 9450LTmkII in 1988. In the late 1980s, amid the shift to 32-bit CPUs and the spread of MS-DOS, Fujitsu announced the FMR-50Λ in 1988, integrating the 9450 and FMR. The following year, 1989, the 9450 series was integrated into the FMR series and discontinued.
