MESS supports both .T77 and .WAV cassette images.

To use a cassette, boot without any disks inserted to get to the F-BASIC ready prompt. Mount a cassette image either beforehand, via the ''-cass'' switch on the commandline, or via the MESS file manager (TAB menu). Then, from the MESS tape control menu (TAB menu, again), select Play. Exit the menu, and at the F-BASIC Ready prompt, type ''run""''. The tape now starts playing, and will load the software on the tape.

Please note, that only .WAV files support recording, .T77 files are read-only.


MESS supports .D77 disk images.

To use a disk, simply mount it via the ''-flop1'' switch on the commandline. The disk should automatically boot the software on it. You can also use the MESS file manager to mount the disk, then restart the system with F3.

Please note, that for now at least, .D77 files are read-only.

History and Trivia

Fujitsu was (and still is) japan's leading electronics company. This computer was the successor of the FM-8 itself first member of the Fujitsu FM (for "Fujitsu Micro") range of computers, extending from hobbyist home computers up to 16-bit machines for the business market.

The FM-7 was conceived as a cut-down version of the FM-8, eliminating the bubble cassette feature, and thereby achieving greater compactness and significantly lower price. But it also offered features not found on the FM-8, like a real sound synthesizer LSI providing 3 voices and 8 octaves. This made it the ideal hobby japanese computer at the time.

As the NEC PC series and the Sharp X1 and X68000, these computers were very very popular in Japan. They all had impressive characteristics in relation to the European and American computers counterparts.

The Most outstanding feature of the FM-7 was the quality and speed of the graphic display.
