Certain Yamaha samplers (such as the TX16W
) used floppy disk drives to store
their data. The disk
format ("MSX-DOS") was almost DOS/TOS-like, but a few minor differences gave TOS a
really hard time to understand the format:
- Filenames with blanks
- FAT backup copy missing
This small program patches those problems away, making the disks TOS-compatible.
Hmmm... after all these years, it occurs to me that "MSX-DOS" might actually
be the same DOS format as it was used for
. Not too unlikely, in fact,
since Yamaha was one of the promoters of that homecomputer standard. Also,
Microsoft played a key role in this initiative, and it's reasonable to assume
that they would use a DOS-compatible disk format. Can anybody
confirm this hypothesis?
Those Yamaha sampler disks also had an interesting protection scheme on them.
If I remember correctly, only protected disks were accepted by the Yamaha
sampler, so you couldn't simply format a floppy disk using a DOS or TOS
box and just use it on the sampler.
Yamaha Protector installs the protection scheme on unprotected floppy disks,
and it can remove the protection from protected media.
I once wrote this tool for a specific customer, and if I remember correctly, he probably
paid for the code, which is why I am not posting it here. If you are that customer,
please make yourself known, as I would like to release the tool here as well.
