- NegativeLatency 3y agoI’d imagine it’s very hardware specific
- rasz 3y agoNo, no standard Shugart interface compatible floppy allows you to do that.
- scoot 3y agoThanks, yes, the article seems to confirm that: "There are 80 tracks on your average 3.5" floppy drive. You can select a given track by pulsing the STEP pin and combining it with the direction select pin."
- hinkley 3y agoYeah I haven’t touched this stuff in twenty five years. It was sectors not tracks they futzed with. The first few generations of consumer hard drives adopted some of these same techniques.
- hinkley 3y agoToo late to edit. It was extra sectors not tracks, although is looks like some people added another track or three at the edge of the disk.
