#floppydrive

1 post1 participant0 posts today

Well, my newly repaired Commodore 8050 broke down. Again. Not even 45 years old and already having issues! Drive number 1 does not spin anymore. The drives spin their motors up when you close the drive latch, as to center the disk. This does not even happen. So something is off. A bit of probing on the connector reveals that pin 8 from the top is the latch.

Today was another day where I spent some time on debugging my wonky Commodore 8050 floppy drive. I did more cleaning, testing, swapping of mechanisms, and nothing REALLY worked. Apart from the fact that lying on its side the drive 0 would work better, but not perfectly. Doesn't that sound weird? It would suggest a mechanical issue which "fixes" itself by gravity, so to speak. Right?
RIGHT?

WRONG!

Worked up my courage to work on the 8050 again tonight. The video shows a pretty stable, albeit slightly slow drive mech. The center ring should be perfectly stable. It is drifting ever so slightly clockwise. However my potentiometer is already maxed out. This is probably the old motor giving everything. :)
I can lower the resistor feeding into the pot a bit. That should give more current to the motor.
