I remember, a few months back, seeing a post on either this site or DIY-CNC, stating that a floppy drive had a driver circuit built in. Fair enough...it would have to have one.

But, I also remember That someone said you could control them, directly, just by exciting certain pins on the floppy connector. I looked up the pinouts, and there is a pin marked direction, and some others labelled things like drive 1 motor enable. Sounds like it might take step and direction inputs, directly.

Does anyone have this information? It sounds perfect for a simple experimental unit...
