     The Franklin ACE is highly compatible with Apple II's; so, an ACE
80 CP/M card may be very similar to the one which was used in Apple
II's.

     If a boot disk for the Apple II or ACE CP/M card is available on an
archive, I have not found it. A pretty good bet is to post a Want to Buy
ad on comp.sys.apple2.marketplace. (Be sure any sellers know you are
talking about a boot disk that will work with an ACE CP/M card.)


     DOS 3.3 boots fine on a Franklin.

     ProDOS includes a ROM check which can mess up booting. As shown
below, removing the check is not difficult ...

039- How can I boot ProDOS on my Franklin computer?

     In an old Apple Clinic note, Stephen Craft listed specific
locations to change after your Franklin freezes. You could then restart
via a 2000G from the monitor.

     It turns out that the bytes Stephen was diddling are D0 03 in the
sequence 69 0B D0 03 A5 0C 60.  The sequence is found in all versions of
ProDOS I've checked so far.


     To fix the booting problem, try this:

 Start Copy II+ (can be a DOS 3.3 version) and select "Sector Editor"

 Swap-in the ProDOS diskette

 READ Track 0, Sector 0

 Search for (Hex bytes): 69 0B D0 03 A5 0C 60

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

 
     This patch has no effect on ProDOS functioning on regular Apple
II's. In fact, most users probably have diskettes on which the patch is
already present.
