Oh wow! That is handy to know. The apple docs make it sound like putting a different drive than the card is named for on it will make them both explode. So all you need is a DB19 to 20-Pin-Header adapter and any drive is good on any card; that's pretty awesome.

I guess that means no DuoDisk on a Disk ][ card then? (/wants a DuoDick)

Yesterday I only happened to be in a ][ mood and decided to organize my stuff. Today, I have a mission. A lady from my church wants to recover her data in the form of 5.25 Floppies said to be made on apple ][ (not sure what model). I told her I would see what I can do. So, I'm off to try and learn DOS.

Thanks for your help David!
