[comp.sys.apple] Cat Track $11

PGOETZ@LOYVAX.BITNET (12/19/87)

Files are normally on track $11 (17 dec.. deci... I can't say it.)
$AC01 in DOS 3.3 tells you what track the VTOC is on. Presumably the VTOC
is sector 0 of the catalog track (you see, the first few bytes of the VTOC give
the track & sector of the catalog, but it's usually VTOC: T11 S0
Catalog: T11 SF-1). You have a few options (in theory, anyway):
1. Boot normal disk.
   CALL-151
   AC01:xx where xx is the track# of the nonstandard disk
   Load a file or two off the strange disk.
   AC01:11
   Save them onto the normal disk.

2. Initialize normal disk. Copy T11 S0 to Txx S0.
   But first (curse glass displays) edit it so Txx S0 is marked as used, so you
        don't write over it.
   Then copy T11 S0 to Txx S0.
   BLOAD FID
   CALL-151
   AC01:xx
   803G (runs FID)
   Now Txx S0 points to the catalog on both disks.
   After copying files, copy Txx S0 on the normal disk to T11 S0.
   Then edit T11 S0 to show Txx S0 as free.

3. Look around in FID for the number $11. Make some patch so it will read
   from disks with the VTOC on Txx, but write to disks wi. VTOC on T11.

Regarding piracy: Let's call a truce and just not mention it anymore.
