Apple again - Disk ]|[ this time...

Having got the Mitac A2 clone up and running (checked out the 80-column output today and that was fine - only casualty in the whole machine was one cap that had gone high-ESR), I've dug my Apple /// out of storage... Disk ]|[ question - should the ribbon cable to the internal drive be plugged into J2 or J3 on the drive's analog board (does it even matter)? A long time ago I disconnected mine as a precaution; the drive began eating disks, but I didn't have time to get to the bottom of it at the time - I suspect it just needs a good clean. I can't for the life of me find where I made a note of which socket the cable plugs into. Normally I leave myself a note somewhere in the machine for things like this, but for some reason I haven't with this one :-( cheers J.
