    Seems I was mistaken then. I originally heard the UniDisk 5.25
had a DB25 port with removable cable, after speaking with someone 
who was selling one on comp.sys.apple2.marketplace (Chet Gerhardt?).
It was a UniDisk 5.25, but most likely either a very early model
or pre-production prototype. Come to think of it, he did also find 
a "DuoDisk 3.5" in his area months before, so it's quite possible. :)

    I suppose then the UniDisk 5.25 is identical to the Apple 5.25, 
expect for the case color and possibly the lack of a security loop
connector. I've not personally seen a UniDisk 5.25 other than in
ad booklets and magazines. Sorry about any confusion this caused.
