Fujitsu FM-7

The FM-7 ("Fujitsu Micro 7") is a home computer created by Fujitsu. It was first released in 1982 and was sold in Japan and Spain. It is a stripped-down version of Fujitsu's earlier FM-8 computer,[2] and during development it was referred to as the "FM-8 Jr.".

Although it was designed to be a cut-down version of the FM-8 (with the FM-7 costing 126,000 yen, compared to 218,000 yen for the FM-8), most notably removing the (expensive) bubble memory technology, the FM-7 was given a more advanced AY-3-8910 sound chip capable of three voice sound synthesis, leading to a strong uptake among the hobbyist computer market in Japan and making it a more popular system than the FM-8.

The FM-7 primarily competed with the NEC PC-8801 and Sharp X1 series of computers in the early 1980s. It was succeeded by the FM-77 series of computers in 1984, which featured backwards compatibility with the FM-7. The FM-77 series was later succeeded by the 32-bit FM Towns in 1989.

The FM-7 is based around the 6809 chip, which was also used in home computers such as the TRS-80 Color Computer and Dragon 32/64, as well as several arcade games. The computer has two MC68B09 CPUs running at 2MHz. One was used as central CPU, the other as graphics processor

The FM-7 ran the OS-9 Operating Sytem, which is compatible with the Tandy Color Computer
