DFS to MMFS Transfer - hoglet67/MMFS GitHub Wiki

It is a common requirement to copy discs between SD CARD and Physical Floppies.

This is an open-source project and comes with no warranty as normal but there is a bigger issue with disc copying:

YOU CAN GET THE SOURCE AND DESTINATION WRONG. The software can work perfectly but with disastrous consequences if you overwrite something precious.

BEWARE!

MMFS does the copying with a small BBC Basic program which has the following features:

• discovers the ROM numbers of DFS and MMFS
• prompts for disk numbers
• copies 8 tracks at a time
• Has good error handling

The programs are provided in a .ssd image which is part of the MMFS release and can be downloaded from the release zip and placed in a spare slot (disk) on your SDCARD.

IDTOM

This copies from floppies to SD Card. This is great for archiving your precious floppy disks or using them on a PC emulator or BEEB FPGA. Note the drive must be formatted. If it is already formatted you are good to go. Beware however it will overwrite the contents of that disk. If it is not formatted and you want to use say image 200 then either:

*MMFS
*DIN 200
*FORM 80 0

or to save time you can use:

*MMFS
*DIN 200
*DOP R

Will prepare the disk ready to write.

IMTOD

This copies from SD card to floppies. This can be good for fixing broken floppies.
