that a standard 34 pin floppy would
interchange regardless of the unit.

In the early days of floppy interfaces, before PCs style drives became
"the
standard", there were many annoying little variations that could stop a
floppy drive working when swapped about. Much of that persists in
non-standard
drives used on things like keyboards. Why should they strive for
compatibility
with PCs when we can avoid it and charge extra for a "special" drive?

It used to be that a floppy drive had multiple jumper sets (0.1") that
could
be strapped to configure them, often to do with things like the logic
around
which Drive Select (0,1,2,3) and whether the "motor enable" line would
be
used. Some host systems didn't assert motor enable, so the drive would
be
jumpered to run off JUST the drive select.

It was PCs, I think, that introduced the idea of no jumpers, no drive
select,
just put a twist in the cable, which limited you to 2 "identical"
drives. The
proper floppy spec allowed for 4, but each drive was jumpered
differently, and
connected totally in parallel.


In the XT and early AT days the floppy controller boards could handle
two sets of two drives. Some controllers could be set to one of four
addresses for a maximum of 16 floppy drives on one computer.


This is before you get into weird drives that ran at 300 vs 600rpm and
that sort of thing, where to use them with a PC, some components needed
to be
changed to re-set the rotation speed and frequency response to the data
being
read back.

I did notice 3 or 4 submin 2 or 3 way slide switches inside that Roland
Panasonic FDD, gives a goodly number of permutations

I just destroyed a Roland D-5 keyboard. What a piece of unrepairable
junk. Hopefully, the XP-60 is better built. I could not determine if
the XP-60 media uses 1.44MB or 720KB floppish. What is the make and
muddle drive that is stock for the Roland XP-60?

I recently repaired a Korg DSS-1 with the traditional dead floppy disk
drive problem.

If your XP60 requires a 720KB floppy drive, instead of the usual
1.44MByte floppy drive, you have to find one that has suitable jumpers
available. This might also help:
<http://blog.retrosynth.com/archives/2005/08/fun_with_akai_m.html>
If you're lucky, the only jumper you'll need to move is the drive
select jumper, usually labeled DS0, DS1, DS2, and DS3. The common PC
drive is set to DS1. Most of the synthesizers I've played with use
DS0.

Oddly, all of the five or so synthesizers I've fixed that had floppy
drives have all had dead floppy disk drives. My guess(tm) is that
they die from static discharge while shoving the floppy into the
drive. That's what killed mine. I've thought of electroplating the
plastic front panel of the drive with metallic chrome or other metal,
to discharge the static before the floppy enters the drive.

This one is back with its owner. The FDD would solenoid? click at power up
but no front LED, I assume a leads/connector problem unless a stuck spindle
could lead to lack of LED

It's likely that it will accept any commodity PC style floppy drive.
Just be sure to check the drive select line, which is probably set to
DS0 (drive select zero).

Only $129 plus tax, shipping, handling, etc for a replacement. What a
bargain:

This review kinda hints that you can do editing on the PC, save to
floppy, and have the XP60 read the floppy without conversion games.

It's probably just easier to cram in a common floppy drive than to
figure this out.

I had similar troubles with the S330 sampler floppy drive. A standard PC
one didn't work but someone told me that floppy drives with jumpers on
their back work if you set the right ones. Could not yet find a drive w/
jumpers to test if the advice was BS or not though.

I have an old S-20 that the floppy failed. Not a standard floppy. The
belt had turned to goo. After replacing , the diskette would not read.
Some tweaking of the head resulted in the disk to be read. Not sure
this applies to 60 but may be worth considering.

As I remember, early Roland units used the 3 inch Hitachi 360k
byte minidisc. Electromechanically, they looked like the 5 1/4 inch
DD drives. (Half the bit rate, and 300 RPM). Other major users of
them were the Amstrad computers in the UK. And, I think, fancy sewing
machines of the time.

This is a Roland S10, don't know why S20 came to mind. Anyway you are
100% correct about the drive. I've done some research on it after owning
it for several years. It was given to me by a relative who had purchased
it new 20 some years ago. I have around 100 disks for it. It's a very
nice sounding unit. You can sample into it and it has a good arpeggio
function. Also works well with MIDI.
