Mac Plus Floppy Eject Motor Won't Stop
Hi,
Why is this? I thought I saw somewhere that I could cut a wire on the ribbon cable to fix this, assuming it's not the drive itself that's acting up (it seems to otherwise work fine, booting up the machine and all, so I kind of doubt the drive's at fault).
Any ideas out there?

There is a mechanically actuated switch mechanism, in the motorized disk eject unit.
- You could swap that whole unit out for a working one
- You could just unplug the eject unit
- You could take apart your eject unit and see why its not auto shutting down the eject motor.

Hi,
I checked it, and it seems to be OK.
I suspect a replacement eject motor would behave the same way.
I will try borrowing a floppy cable from another machine tomorrow to see what happens.
I definitely thought I saw somewhere that cutting a certain wire of the cable disables some sort of sensor or cut's off some sort of control signal from the floppy drive which can cause this problem in certain machines.

I had SE FDHD with a bad filter chip on it, the issue with that was, It would randomly tell me the disk i have inserted is unreadable, and would I like to eject it? Even when there was no disk in the drive.
Hi,
Well, I tried different cables, different drives, even a different logic board. All had the same problem.
Why??
Any thoughts or ideas?

Hi,
I found what I thought I saw before:
Floppy drive won't stop ejecting
It says to delete pins 9 and 20 to restore proper operation.
I did pin 9 (I think), so I just need now to understand where pin 20 is.
The wire which corresponds to pin 9 is 3 wires to the left of the right edge of the cable if the colored stripe is on the left. What wire corresponds to pin 20?

you can try this lift the green board at the front of the motor. just lift it a little.
there is a reed switch under it clean out the dust, than push the board back down

On all three drives?
I checked on the first one, and aside from seeming a little fatigued, it was OK. I bent it back tinto shape and reassembled it to find the same exact problem.
I think it has to do with the cable problem as described in the thread linked above. I just would like to know how to modify my cable such that those two pins (9 and 20) are disconnected. Maybe then it'll work.
I might add that this cable isn't original to this computer.

Problem Solved!
I found a spare, yellow-stripped cable, and, for reasons unknown to me, it works perfectly! I now have yet another fully functioning Plus.
I still have the other cable, and, even though I cut a hole in it, it seems to work just fine, so I'll keep it for something else (other than a Plus).
This should be documented more thoroughly and completely.
Thanks!
