Fujitsu Micro 8
Introduced may 1981, the FM 8 was one of the first Fujitsu micro computers (after the LKIT-8 hobby computer in 1977). In any case it was the first member of the FM series, FM standing for Fujitsu Micro. At that time its features were really impressive: bi-processor (even an additionnal Z80 cpu could be installed), 64 KB RAM, bubble memory, built-in chinese characters ROM, 640x200 high resolution with 8 colors and no proximity conflict!
The FM-8 was developed by employing innovative design and state-of-the-art semiconductor technology, and was designed for use in a variety of fields, ranging from high-level hobby use, to business applications and process control.
The Japanese Computer Museum specifies:
The FM-8 had the following features:
- Equipped with two Motorola 6809 8-bit CPUs (main and sub)
- The worlds first use of 64 kilobit DRAM (like that in large main frame computer) in a microcomputer (64 kilobyte main memory)
- Japanese language display using Chinese character (kanji) ROM (JIS level 1 2,965 characters, optional)
- High-resolution color graphics (640x200 dot, 8 colors selectable at each dot)
- The provided operating systems (OS) included F-BASIC, as well as UCSD-PASCAL, FLEX and CP/M (required Z80 card option)
- First use in a personal computer of bubble memory as external memory (At the time of announcement, the machine had a bubble cassette with a 32 kilobyte capacity. A 128 kilobyte cassette was added later. Bubble memory did not catch on, however, and was eliminated from the standard features in the FM-7.)
When booted, a menu offers different choices:
1 - F-BASIC (ROM/DISK mode)
2 - DOS (mini- floppy disk)
3 - Bubble memory
4 - DOS (standard floppy disk)
There are a lot of character sets available (8x8 matrix): 69 alphanumeric char., 63 katakana signs and 62 graphic symbols. And for characters with a 16x16 pixels matrix: 2965 chinese characters (JIS standard level 1) and 453 non-chinese characters (JIS non-chinese characters).
Optional mini floppy disks could be connected (320 KB each), as well as an expansion unit which allowed many things (voice input/ouput, hard disk connection, RS232c interface, analog interface for measurement,etc.)
In November 1982, Fujitsu announced a upper model of the FM-8 called the FM-11, and a mass-market model called the FM-7.
