The FM-7 ("Fujitsu Micro 7") is a home computer created by Fujitsu, first released in 1982, only sold in Japan. It is a stripped down version of their earlier FM-8; during development, the FM-7 was known as the "FM-8 Jr.". Although it is known as a lower cost model, most notably removing its (expensive) bubble memory technology, the FM-7 was given a more advanced sound synthesizer, leading to a strong uptake among the hobbyist computer market in Japan and making it a more dominant system than the FM-8. This model competed primarily with the NEC PC-8801 and Sharp X1 series of computers in the early 1980s. It was succeeded by the FM-77 series in 1984 (which were backwards compatible with the FM-7), and later the 32-bit FM Towns in 1989. The FM-7 is 6809-based, similar to the TRS-80 Color Computer by Radio Shack; some software is compatible with both systems. ==Hardware== *Two MC 68B09 CPUs @ 2 MHz: one main CPU and one graphics processor. *Screen Resolution: 640×200, 8 colors OR 320×200, 262144 colors *Memory: 40 KB ROM, 64 KB RAM *Sound: 3-channel (AY-3-8910) PSG chip, built-in speaker mounted near the top of the unit. *Interfaces: RS-232, monitor and Centronics ports, expansion slots. *Storage: 5.25" floppy disk *Operating system: OS-9, (compatible with Color Computer) *Three slots for optional plug-in cards, including a Z-80 CPU and additional RS-232 ports. *Full-size keyboard, with keys handling multiple functions (as many as 5, depending on what SHIFT/KANA/GRAPH/etc key is pressed). *10 Function Keys at the top, pre-programmed with shortcuts (LIST, etc.). *Numeric keypad (on right) and cursor-control keys (upper-right). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「FM-7」の詳細全文を読む スポンサード リンク
