Modifications
84 track seeking
Unmodified drives will not be able to seek 84 tracks. A major modification is required to enable this.
The modification can be performed by following these steps:
- Unscrew the springs that hold the head assembly guild rod on the stepper motor side.
- Pull out the guide rod about half way.
- Use a rotary tool to grind down the head assembly end stop as pictured.
- Clean the drive of any metal dust.
- Push the guide rod back into its resting position.
- Screw down the springs that hold the guild rod in place.
