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. Disk
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. FM-7 compatibility
All FM-7 software should be backwards compatible with the FM-77AV
History and Trivia
The FM 77 AV was an impressive system in 1985. It's a good example of what was developped in Japan and we never heard of in the rest of the world.
The system has great audio and video features, hence the AV for "Audio and Video". It can display 640 x 200 pixels in two colors, or 320 x 200 in 4096 colors ! There is even a multipage mode where you can define two 460 x 200 screens with 8 colors each, or six 640 x 200 monochrome screens !
There are a lot of graphical symbols already stored in memory (each symbol / letter is composed by 8 x 8 pixels) : 69 alphanumeric symbols, 63 kakatana signs, 63 hiragana signs and 62 graphic symbols. Moreover, the system is capable of displaying 3418 chinese and asiatic characters with a 16 x 16 character matrix (text resolution is thus of 40 x 12).
Last but not least, the FM 77 AV offers superimposition features...
On the sound side, it offers three FM voices and three more PSG voices. Other cool features include infra-red keyboard and built-in real time clock.
There were two models : the AV-1 which has one 3.5" disk-drive (double density) built-in and the AV-2 which is equipped with two of these drives.
