This was a business personal computer from Fujitsu. The FM-11 was announced as a higher-end model of the FM-8 in November 1982, simultaneously with the mass market FM-7 machine. This machine was a high-performance personal computer designed for business use, and the series was comprised of 3 models the FM-11ST, FM-11AD and FM-11EX. The FM-11ST was a low-cost machine. The intermediate FM-11AD later developed into the FM-11AD2 and FM-11AD2+, and was consistently popular as an OS-9 machine. The top-end FM-11EX was a true business computer, equipped with a 16-bit 8088 and 8-bit 6809 main CPU (either could be selected for use), and OS CP/M-86 (16-bit) and F-BASIC (8-bit). It developed into the FM16β(Beta),, via the FM-11BS.
