This will not help your Franklin Ace 1000, unfortunately. Amazingly,
their Keytronic-based keyboards have little pieces of foam that
provide the "spring" - and they have turned to dust on you. There is
a page that talks about repairing same:

I'm always (years and years of lurking off and on) amazed at how deep
you folk here are able to mine. Thanks for the exceptionally
informative resource.
And my apologies for suggesting an approach that won't work for a
Franklin keyboard. ;-)
Okay, I'm at a loss. How do I get the drive to operate without a disk,
especially move the head rapidly along it's drive?
For slot 6, to turn on:
PRINT PEEK(49385)
to turn off:
PRINT PEEK(49384)
Thanks for this as well. I haven't tried it yet, but I assume it's an
on and off toggle, but does not cause the head to rapidly move back and
forth as it would reading a disk under ADT. Is that correct?
You are correct, this will cause the drive motor to turn on, with or
without a disk inserted, but will not move the head.
ADT only moves the head rapidly back to track 0--all other movements
are just single track seeks. The squealing you report doesn't sound
like it is related to head movement, though it may be related to head
*position*.
You can always run ADT or a copy or verify program until an inner
track is reached, then RESET the Apple, then do the PEEKs. You can
also use POKE, or "X=PEEK(...)" to toggle the drive motor.
Keep up the good work! :-)
As long as I keep getting all this wonderful help and encouragement, how
could I not?
Excellent!
