Apple 2 ProDOS (Virtual Disk) Utilities

ProdosFS is a command-line utility to create and manipulate virtual ProDOS volume images for emulators.

NOTE: This is still a work-in-progress.

Commands that work:

• cat
• catalog
• cp (Only Seed (file size <= 512 bytes), and Sapling files (file size <= 128 KB) are currently supported)
• dir
• get
• init
• ls
• mkdir
• rm
• rmdir

Usage: <dsk> <command> [<options>] [<path>]

    cat      Catalog (short form)
                 [<path>]            Path of virtual sub-directory to view

                                     NOTE:
                                         You can't delete the root directory: /
                 -f                  Force removal of sub-directory
                                     (Normally a sub-directory must be empty)

Where <dsk> is a virtual disk image with an extension of:

    .dsk  (Assumes DOS3.3 sector order)
    .do   (DOS3.3 sector order)
    .po   (ProDOS sector order)

NOTE: To skip always having to specify the <.dsk> name set the environment variable:

           PRODOS_VOLUME
e.g.
    export PRODOS_VOLUME=path/to/volume.po
    set    PRODOS_VOLUME=disk.dsk

Three different disk sizes are accepted for init

   prodosfs test.dsk init -size=140 /TEST514   # 5 1/4"  (140 KB)
   prodosfs test.dsk init -size=800 /TEST312   # 3 1/2"  (800 KB)
   prodosfs test.dsk init -size=32  /TEST32M   #HardDisk ( 32 MB)

Examples:

    prodosfs test.dsk init  /TEST
    prodosfs test.dsk ls
    prodosfs test.dsk cat
    prodosfs test.dsk cp    foo1 foo2 /
    prodosfs test.dsk mkdir bar
    prodosfs test.dsk cp    foo2      /bar
    prodosfs test.dsk get   /bar/foo2
    prodosfs test.dsk rm    /bar/foo2
    prodosfs test.dsk rmdir /bar

    prodosfs b140.dsk init  -size=140 /BLANK140
    prodosfs b800.dsk init  -size=800 /BLANK800
    prodosfs b032.dsk init  -size=32  /BLANK32

Given these steps ...

`` echo. > foo1.txt echo. > foo2.txt echo. > foo3.txt

REM Windows
echo a020a90220a8fc8d30c0a92420a8fc8d30c088d0ed60 > softbeep.hex
certutil.exe -f -v -decodehex                       softbeep.hex softbeep.bin
REM Windows

prodosfs test.dsk init  -size=140 /TEST
prodosfs test.dsk cp    foo1.txt /
prodosfs test.dsk cp    foo2.txt /
prodosfs test.dsk cp    foo3.txt /
prodosfs test.dsk cp -aux=$0300 softbeep.bin /
prodosfs test.dsk catalog

... it will produce this output
