Hey, first time posting here i recently picked up an apple IIc that was not working and spent the time fixing it.
I don't have a ton of history on the unit, it was in fairly good condition, when i opened it up it had a Z-RAM Ultra 1 inserted inbetween the MMU and CPU removing that got it to boot. Tested the RAM it works.
Floppy drive is not working, at first it was not making the normal clicks I remember.
Checked drive, cleaned head, Lubed rails (lithium grease)
When powering on the head will click when it is manually returned to home. its almost as if the stater motor is not getting enough power, or is being sent the wrong instructions.
If i push the read/write head to the furthest position from home it will take several reboots for it to return home and make clicking, slow progress which is why my instinct was that the rails needed greasing.
Saddly i don't have anything that is "Known Good" just two drives (one external) and the internal one it came with that do the exact same thing when connected internally.
Using the external connector does nothing for either drive, it will light the red LED on the drive with the housing for a split second when connected when powered on, but no movement when i try pr#5 it will say check disk drive and no lights or noise through the external connector.
I think it may be the IWM as both drives behave the same. maybe they both need re-capping.
any thoughts or ideas?
i recorded video of the read write heads behavior:
thanks in advance
