The first way did weird       things, what exactly I can't remember (and it was a Color Computer).       But once I had the drive connector the right way, I realized that since       the wrong way puts ground on all kinds of pins that are used for things       (since one side of the connector is just ground pins), it would cause       activity without actually working. The control pins tend to require       ground to be "on", so grounding things like the motor on and head       select and write and whatever else ended up with a spinning drive       that actually erased what I had on the floppy.              The connector at the floppy I don't think can be reversed, since       there should be a slot to make it clear, but I don't know what       the connector is at the drive controller. If it's ambiguous,       and reversible, that might be the problem.               Michael              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
