re: Repairing a Floopy Drive on Technics KN2000 + some Korg models + some Yamaha models listed at the bottom of this message.


Bustedgear.com Floopy Drive belt repair http://www.bustedgear.com/part_belt_floppy.html

I don't know if this is a solution to repair a broken Floopy Drive on a Technics KN2000?

I found this info. via a "Seller" on eBay.

According to the web site this "fix" also applies to:

For: KORG X3, X3R, X2, i2, i3, i4s,
YAMAHA PSR-SQ16, PSR620, PSR1700, PSR2700,
YAMAHA SY77, SY85, SY99, W5, W7, MDF2,
and TECHNICS KN2000

I hope this info is accurate, and helpful to my friends on Synth Zone.

If the floppy drive is a standatd PC compatible one then I'd be very inclined just to get a PC drive.

However if it's worth selling the belts as repair items then I presume the drive must be non-PC standard format.

Maybe it's an older (Apple?) format which use a variable spindle speed to maximise capacity.

Failing that there is another possiblity for the brave / stupid / desparate. TEAC made a very flexible floppy disc drive quite some time ago (early 90s?). It is notable because it has a pin matrix that is configurable with jumpers and can be configured using this matrix to operate in a number of ways. This is important for me because I had a floppy disc failure on my Ensoniq SD1. Ensoniq used a variable speed floppy disc format. By luck I had one of these drives available and after an hours worth of jumper setting changes I chanced upon the right combination and was able to read/write floppies on my Ensoniq again. This remains the case today, it's just a pity it goes out of tune all the time!

I have a hardcopy of the matrix configuration page from the floppy disc specification sheet, which I can copy and email if anyone needs it.

You may guess from the waffle that this sheet is elsewhere at present, and that until I see the sheet I can't tell you the exact model number of the drive unit!

I'll post the model number tomorrow.

On a related note, this thread appeared on the Korg forums a while ago. Rather than repairing floppy drives, it concerns replacing floppy units with a 'floppy emulator' and its advantages.

Maybe it could work on other brands as well.

I like the idea of an emulator, especially now that I've found my piece of paper showing jumper settings on the floppy drive but regrettably it doesn't tell me the model number!

The TEAC FD235HF drive has a limited set of confiuration jumpers (http://matthieu.benoit.free.fr/pdf/FD235HFA5XX%20(Rev%20B).pdf) but I can't say whether these are sufficient to do the job, sorry!

13 bucks for a belt? it's usually a few dollars?

Good point re: price for Floppy Drive belt. For Technics KN2000 + some Korg models + some Yamaha models.

I have since noticed one for a lot less on this current eBay auction:

http://www.ebay.com/itm/Floppy-Drive-Belt-Korg-N264-N364-X2-X3-and-More-/160907650323#vi-content

This auction was still active as of October 26.
