Duodisk cable pinout wanted???

[John Banion <john@jb.com>]

I have a duodisk drive with no cable model number a9m0108.  The unit has
a db25 on back.  I also have a card model number 655-0101 labeled I/O
controler, It has a db19.  Does the duodisk use this controler, or
somehow use a standard diskII interface with a special cable?  I need to
know which controler works with the duodisk and what that cable pinout
is some I can make one.  The local goodwill has a nasty habit for
loosing all the cables!

Thanks.
