- Short: Extract files from Apple II Disk Image
- Author: agmsmith@achilles.net (Alexander G. M. Smith)
- Uploader: agmsmith@achilles.net (Alexander G. M. Smith)
- Version: 1.0
- Type: misc/emu
- Requires: AmigaOS 2.04+
-
- A2DiskDump is a utility which takes an Apple II DOS 3.3 disk image (in
- "DOS" order) and extracts all the files from it in one batch,
- optionally converting text files to AmigaDOS format.
-
- With no special arguments, it just gives you a catalog listing of the
- disk image. You can optionally save the files, convert text to Amiga
- format, only do text files, leave on or remove headers from binary
- file, etc. See the online help for more details.
-
- The disk image is made by dumping it from a real Apple 5.25 inch DOS
- 3.3 floppy disk using a utility like ADT (A2ADT4AM for the Amiga) and
- an Apple with a serial card. The disk images are also useable /
- creatable with Apple emulators like Apple2000 for the Amiga.

- A2DiskDump is a utility for extracting all files from an Apple II
- DOS 3.3 disk image file (like the kinds made from ADT the Apple Disk
- Transfer utility). The files are written to the current directory,
- using the name from the disk's catalog, with illegal characters
- replaced. By default, a comment is attached to each file with its
- catalog listing plus secret info (file length, start address).

-
- DISKIMAGE/A is the required path name to the disk image file, which
- is from an Apple II DOS 3.3 disk (256 bytes per sector, 16 sectors per
- track, 35 tracks) and is 143360 bytes long.
-
- DROPHEADER/S is a switch which if present, leaves out the header info
- in binary files. Otherwise, binary files will have a 4 byte header
- containing address low/high bytes followed by length low/high. Text
- and other file types aren't affected by this switch.
-
- KEEPTAIL/S is a switch which when present, includes the garbage past
- the end of the file (end of file determined by the header for binary
- files and BASIC files, or first NUL in text files). This is useful
- for random access text files used in databases, where the file contains
- NUL characters for fixed length record padding. Yes, the code does
- handle sparse files, filling in the non-existent sectors with zeroes.
-
- CONVERTTEXT/S when present switches on conversion of text files from
- Apple II format into text file format (high bit set to zero and
- carriage return characters turned into line feeds).
-
- TEXTFILESONLY/S makes the dumpfile feature only dump text files,
- skipping over all other file types.
-
- NOCOMMENT/S specify this switch if you don't want to have comments
- attached to the files. The default is to have comments, with the
- comment text being much like an Apple II catalog listing.
-
- VERBOSE/S switches on debug messages and extra status info etc.
