Vintage Synth Repair

I am working on a 3.5 floppy drive replacement for all these 3.0 
quick disc machines like the older Akai, Roland and Korg units. 
Anyone know where I could get a copy of the Roland S10 sampler 
schematic?

Its been a long time since I've seen one of the 3" discs, but I seen 
to recall that they use a single track that spirals in toward the 
center, like an old vinyl record.  The 3.5" floppy drives use 
concentric circular tracks, which are separate from each other, and 
each track is individually recorded.  This would make it impossible 
to simply plug the drive into the unit.  You could use a small 
computer between the unit and a floppy, having the computer send and 
receive data to the synth in the 3" disc format, using its own memory 
to temporily store the data, and then reading/writing to the 3.5" 
floppy.

I'm not terribly up on all the technical details, nor
do I have the schematics for the S-10, but I
definitely urge this guy to try!  I have an S-10, and
those QD's, besides being hard to find these days, are
incredibly unreliable.  I've also noticed that a few
early stand-alone MIDI sequencers use those loathsome
QuickDisks too.  Ugh!

I don't have a schematic for the S10, but I just wanted to post this 
message to express my encouragement at what you're attempting!!!  If 
you manage to get some results from what you're doing, be sure to let 
me know - or better yet, just post it on this list.  I would really 
love to upgrade my S10 for use with 3.5 floppy discs.  Why the hell 
did they come up with those stupid Quick (as if) Discs in the first 
place?!?  I love my S10 - sure, it's an obsolete, underpowered piece 
of crapola, but (a) it's my favorite for creating quick 'n' dirty, 
grungy sounding drum loops and sampling electric guitar power chords 
for that "obviously sampled" sound, and (b) there are actually some 
halfway decent samples floating around the 'net for the silly thing...

Well, It may never work but I have been reading the tech notes of a computer nut who managed to do this with an old computer that was only setup with the quick disc or mini floppy disc media drive. 

I am looking into it now. If anyone has a unit that needs a replacement floppy drive let me know I may have an answer.

Well, get down with your bad self, I say.

I was just contacted earlier today by a guy whose S-10's drive broke, and he's sending me a bunch of sound-bites (he's a DJ, ya see) on QD to convert to wav's and put on a CD-R for him.  I just hope my
S-10 can still read 'em (it still works, but it's damn finicky).  Anyway, I get to keep all the QD's (he said there's 50 of them or so), and he'll also be sending me his S-10, which he won't need
anymore once he has the CD-R.  Like I said, I like the S-10 - my S-550 is much tonier and high-class (and has a better sample library), but the S-10 is great for doing things on the fly, quick and
dirty and lo-fi, and it's a shame that so many have been abandoned just because of a short-sighted media decision.  Incidentally, I read something just a bit ago that seems to suggest that the only
reason for the proliferation of QD's is because they could be mailed at a lower postage rate than 3.5" floppies in Japan!!!

Something you might want to check if your quick disc is not working:


If I remember correctly, the quick disc drive has a small felt pad to 
hold the disc against the head.  It was pretty common for one of 
these to get knocked off when the disc was inserted, after which the 
drive would not work correctly.
