Regarding the problem of booting ProDOS on the Franklin ...

    In an old Apple Clinic note, Stephen Craft mentioned a problem similar
to the ones mentioned here. He was running a Franklin 1000.

    His cure was to press Ctrl-Reset after the machine freezes up when
booting ProDOS. Then go to the monitor and enter two NOP (EA) instructions
at a specific address depending upon the version of ProDOS. Restart ProDOS
by doing a 2000G.

    Just early versions of ProDOS are listed-- this is an OLD article--
and, evidently, some Franklins do not permit a RESET.

    It turns out that the bytes Stephen was diddling are D0 03 in the
sequence
69 0B D0 03.  The sequence is found in all versions of ProDOS I've checked
so far.

    So, to fix the booting problem, try this:

 Start Copy II+

 Select "Sector Editor"

 Swap-in the ProDOS diskette

 READ track 0, sector 0

 Search for (Hex bytes): 69 0B D0 03

 When you find the above, change D0 03 to EA EA
    and write the changed sector back to diskette.

 Check the patched ProDOS diskette by booting it.
