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.
