The purpose of the programs you can download from here is to resurrect an 8-bit computer called FM-7 and its variant from 1980s.

For example, you can write a code for FM-7 on Windows, test on an emulator, then use one of the tools here to transfer to the actual machine.

If you happen to be a former FM-7 user, and if you have a program that you want to run on the actual computer, but you only have a disk image for the emulator, you can use a tool here to write-back the disk image on the actual computer by transferring the image via the data-recorder interface.

For this purpose, all I needed was to write a file into a .D77 disk image or .T77 tape image or a .WAV file.  I didn't read something from those images.  Nonetheless, I ended up writing a program to read a FM-7 file from a disk image formatted in the F-BASIC format.  Well, it's a kind of self memo for the future.

By the way, I had to do a lot of reverse engineering.  I already forgot disk format of F-BASIC.  My program may destroy your disk image.  Therefore, always take backups before giving to my programs.

I acknowledge that I used a set of tools written by Mr. Apollo called FTOOLS to reverse engineer XM7 data formats.  Also the FM-7 emulator XM7 helped a lot in writing and testing FM-7 code.  I thank all developers who was involved in the development of XM7 and supporting tools.

I recognized that there are a few FM-7 series users outside Japan who are still maintaining and using the computers, and I am hoping this tool will help those users.

But, the spring semester is starting and I couldn't spend time for writing English translation of the documentations.

I make all source code open.  You can read.  If you are able to keep FM-7 series computer alive, you should be able to read C++ code easily.

Good luck!

Updates:

2019/05/19

• -38400bps option in RS232CDiskBios, T77ToRS232C, D77ToRS232C commands.  It requires an RS232C card that supports 38400bps.

2019/04/11

• -append option in t77save.exe

2019/01/29

• Added T77ToRS232C BIOS Redirector utility.  You can load and run a FM-7/77 tape-based titles in T77 tape image format via RS232C connection.

2019/01/15

• Added D77toRS232C utility.  You can create an actual floppy disk by transferring disk image from Windows PC to FM-7/77 via serial cross cable.  Please see readme_D77ToRS232C_e.txt for more details.

2018/11/21

• Added RS232C Utilities.  (COMTEST for testing RS232C<->COM connection.  232CFILE RS232C<-COM for file transfer.  RAWREAD RS232C->COM for disk imaging and transfer.  MEM2COM RS232C->COM for memory dump transfer)

2018/08/02

• Added 32-bit binary in the archive.  Actually there is no 32-bit environment near me any longer.  I hope I compiled them right.

2018/06/17

• I was compiling in the debug mode.  Now compiled in the release mode.

2018/01/31

• DISK2TAPE: -fm77av option. If this option is given, the writer program will use expanded RAM (64K) of FM77AV to reduce number of .WAV files.
• DISK2TAPE: -use7000 option. If this option is given, the write program will use $7000-$7FFF to reduce number of .WAV files. But, if this option is used, the writer program must be started from the tape mode. If started from Disk-BASIC, it destroys the Disk-BASIC area.

2018/01/12

• DISK2TAPE: Added an option for specifying the target disk drive, but I haven't tested it. It may or may not work.

2018/01/10

• DISK2TAPE: AV40 failed to write to a disk if running a program from DISK2TAPE after booting without a floppy disk in the disk drive.

2018/01/03

• Version 1
