I am trying to fix my Atari 1050 floppy drive.
When I got it, the stepper motor was kinda stuck. I ordered a new one and a PIA IC too because people told me as the motor was "stuck" the PIA could have been damaged too
Today I replaced both but its behavior didn't change: when I power it up, power led lits, the main motor spins (I replaced the belt too), the head moves forward a bit and the activity led won´t lit.
If I continue to power off and on again the head will reach the "upper" limit and keeps there.
It happens connected or not to a Atari XL (tested on a 600XL and a 800XL)
I was worried someone tried to mess with it before and double checked all cable connections inside.
But now, I don't know what is happening.
