In for a power supply fault but while in there, the floppy drive has never
worked. Would it be a standard PC drive? or known simple repairable stock
fault? It does klunk once, on pwering up , sort of PC fashion

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.

Well let me know what you find. The S20 has no ROM based sounds so all
was loaded at and during performance via floppy. These floppies are
roughly the size of a Minidisc. As the diskette was attempting to be read
I adjusted the head height and immediately the disk started to load. I
went back and adjusted the other two axis adjustments by sight to make
sure the head rode true on the surface.

Standard PC 3.5 inch FD in the xp 60 . Removing it and poking around and
refitting I can save to a PC formatted disk and load back a "song" and read
as HEX files on a pc so perhaps stuck stepper spindle or connector problem.

If it's standard it could be replaced with a PC drive, that's good.

In my experience, most (but not all) of these floppys are NOT standard PC
drives. Why this is/was the case I have never really understood. (Unless
it was for the manufacturers to make more money on spare parts). In your
case here, count yourself lucky!

I did once try and investigate whether it was possible to reconfigure
standard drives to work in various keyboards/samplers etc, but at the time
couldn't find enough data, or the time, to do so.

Do you mean non-3.5 inch or not directly swappable FD from a PC to one of
these?
I did not try an ex-PC FD in the Roland.
Noted the type as in the Roland as
Panasonic JU 257A 726P, not researched it, as the green FD front panel LED
was not lit before fiddling and did come on after fiddling and with it
return to function

I once installed a PC DVDRW in a stand alone DVD recorder. However
I used the control boards from the stand alone recorder on the
replacement drive. Both were LiteOn products, the drives were 99% the
same.

Knowing this to work one would assume that a standard 34 pin floppy would
interchange regardless of the unit.


There are legions of Akai, Roland, Korg, Emu and Yamaha owners out there
that dearly wish this were true .....

I understand that. What I don't understand is why you failed to
quote my entire reply.




Are you hoping one day to take over from Phil Allison?

Are you being purposefully evasive?




Lets just leave it there, eh.


Ok but in the future please put some thought into your insults.





Didn't think you could just leave it there.
Ah, a 'last word' obsesso. You're predictable.

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.

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.

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.
