Re: Yamaha SY99 Disk Drive Belt And Battery Holder

2013-04-30 by Paul Krull

Hello Again Folks:
I ended up replacing my old belt driven floppy drive with a beltless Sony drive after experiencing some troubles while trying to clean all of the melted rubber from the old belt off of the fly wheel and spindle of the old drive. I thought I was being careful in handling the drive but the flywheel dropped off of the drive and the threaded axil to which it had been attached disappeared into the disk drive, not sure if I unscrewed it or what. I was not able to put it all back together again in a functional state and the Sony drive fit the same screw holes and has been working flawlessly with my SY disks. I also successfully added battery clips for both CR2032 batteries. I've really been enjoying this synth now that it's working as it should and is full of great sounds. Almost every function while programming involves reinitilizing and with dead batteries you can't do that.
Now I'm almost inspired enough to take on some backlight replacements. The Casio VZ10Ms are both completetly unreadable without a flashlight at this point. Any tips?
Thanks,
Paul T

Subject: Yamaha SY99 Disk Drive Belt And Battery Holder

Hi Folks:
Does anyone know what a suitable replacement belt for the disk drive for the mighty SY99? There's a helpful YouTube video showing how to go about replacing it but what belt should I use and where's a source for it?
Another question is concerning replacing the CR2032 batteries that back up the samples and RAM. They are soldered in place and that makes finding replacements and installing them hard. Has anyone added a battery holder for the CR2032s in their SY99?
Thanks,
Paul T
