Repairs
Belt repairs
The belt-driven floppy drive will stop working once its rubber belt has perished. There are multiple replacement sources:
- Sinclair Spectrum +3, ZX and Amstrad CPC/PCW 3" drives have a belt which is also appropriate and easier to source
- Tototek sells a $6 replacement.
Belt replacement may require recalibration of the drive afterward depending on how bad it has gotten.
