Not yet dumped ... I probably need help with this if there's interest in emulating this one:
Got a Sharp Fontwriter FW-700 really cheap and hoped it might have a nice socketed ROM that would be easily dumpable ...
Turns out, this is really a nice, solid machine with an easily readable 640x400 mono (blue on white) LCD screen and well designed word processing software.
Texts are saved in a proprietary format on FAT formatted 720K DD 3.5" floppy disks, the software can supposedly also import/export WordPerfect files.
The innards are accessed by removing the bottom lid of the machine, everything is accessible, but unfortunately SMD soldered.
The chips, starting top left and going clockwise:
HM514260CJ8 = 262,144 word*16 bit DRAM
NEC 72068GF = Floppy Controller
Mitsubishi M37720S1AFP C604100 = 16bit Microcontroller MELPS 7700 series
Some strange beasts there ...
Other Sharp LH53xx parts are ROM, so I assume the top left chip is the machine's ROM - unless some of it is hiding inside the Microcontroller - I couldn't find a defintiive datasheet on this precise part.
If someone wants a go at dumping the FW-700's ROM, give me a shout and we can work out how I can send the board to you - Germany or Europe would be easiest.
