APPLE2 file system driver for Linux
Copyright (c)2003,2005 GPL Oskar Schirmer (schirmer@scara.com)
This disk format is very simple, it doesn't support subdirectories, nor does it have something like a block allocation table, not to mention inodes. The root directory is simply a list of records, stating the name, the type, the starting block and the size of the file. As there is probably not much use in creating or changing such a disk under Linux, this driver comes for read only access solely. Code files are marked executable, no matter whether there is any loader that is capable of getting the P-code started.
With the UCSD Pascal System, text files are not just character
files, but obey a special format. For the users convenience, this
driver provides automatic text file conversion as follows:
All files are readable in the root directory in raw mode, i.e.
untranslated. For all files of type text, there is a converted
copy found in an artifical subdirectory by the name of '.text'.
The conversion includes:
- CR to LF translation
- NUL character discard at end of 1K-block
- DLE run length code expansion
