Hello All,
I have an Apple IIc plus and have tried to use it with two different Unidisk 3.5 drives (A2M2053). Both drives exhibit the same behavior where they "hang" after a disk format or volume listing. My understanding is that the Apple IIc plus is supposed to be backwards compatible with the Unidisk 3.5 drive. Am I not correct on this?
My IIc plus works perfectly with the 5.25 drive (A2M4050) and Apple 3.5 Drive (A9M0106) so it seems like the drive port is working properly. Also, both Unidisk 3.5 drives work perfectly on a Quadra 605 equipped with a IIe card, so I'm confident that the drives actually work fine.
To add to the confusion, the Unidisk 3.5 drives do not work on my Apple IIgs ROM3, which I thought was also supposed to be compatible.
I seriously welcome any comments/clarity on this problem (it's holding up a few other projects)! TIA!! -kevwaffle
My repository of knowledge on such things says it ought to work - no idea why it's not:

Agreed David,
All of my research suggests that the Unidisk should work fine with a IIc plus. Anyone else out there tried this configuration that could comment on compatibility? Thanks!
