Vitus,

Thanks for the info.  The drive I have here is the same IBM numbers, prob an 
older Mistu drive.  I will try a hack into an old cable at work.
The worst case, I trash an old 486.  Nothing lost.   :}

From what I recall, all the odd numbered pins on a 1.44, 720, 1.2, and 360k 
drive are ground.  It should be funny if I put +5V on pin 3 (above) and the 
controller is at ground.  :}

Will post back in a few days & a few systems.
