Hello all,
I am trying to salvage a couple of Disk II drives, and I've run into this modification. Is this a write protect switch?

If the wiring is connected to the switch detecing whether the write protect notch of the diskette is covered or not, this switch probably does the opposite. It enables writing to diskettes that have no write protect notch like those used to distribute original copies of commercial software that shouldn't be destroyed inadvertently.

That's what I figured. Thanks for the confirmation.
Is there a better version of this somewhere? https://www.apple.asimov.net/d…/Disk2_Repair_Chilton.pdf
I have managed to repair 3 drives out of 5 by just proper head cleaning, head track lubrication, and swapping out the 74LS125.
This is one though is a bit of a head scratcher. Apex II says, that the drive has a good alignment. It reads fine if connected as D2, but unable to read the boot diskette if connected as D1... Any idea?
Connect the drive as D2 and use it to INIT a new boot disk. Then connect it as D1 and try if it boots the diskette created on it. Does this work?

That worked, the disk was spinning too fast.
I always use MECC Computer Inspector to check and adjust to 300 rpm. Maybe you can give it a try.

Thanks for the tip, I'll check it out!
