I don't see much around here for the 9114. But I have one (not an A or B, just 9114) and I've tried it with a 41 and 71 and both report medium errors during the initialize/formatting process. At first I thought bad diskettes as these were salvaged from my old stock from in the 90's. But.. they all pass FORMAT and CHKDSK on a PS/2. 720Ks as HD diskettes don't seem to work at all in the 9114.

What I've done so far - from the ground up....
* replaced the battery and charged it
* fixed a mechanical issue with the diskette seating/ejecting
* cleaned the heads with alcohol
* lubed the rail and worm gear
* run the initialize with the top off - I can see the heads move across the surface of the disk.

Any ideas? Or is there a repair guide for these things?

Thanks!
