October 1st, 2012 - Antoine Vignau and Olivier Zardini, founders of Brutal Deluxe Software, are proud to introduce their newest software to the Apple II community.

“I'm fEDD up” (now version 1.1) is Brutal Deluxe's second answer to nowadays preservation of 5.25" diskettes on the Apple II. Its main features are:

  • Essential Data Duplicator compatible
    If Utilico Microware's EDD or compatible card is installed in your system, it will use the card's powerful features to read track data.
  • Nibble and timing preservation
    It saves raw nibbles and their associated time cycles in separate files.
  • ProDOS compatible
    That may sound weird but that is important. SST is no longer needed ;-) The requirement of two drives is no longer needed.

The source code of the program is available.

How to use?

       - 1. Launch the application
	       Double-click the "imfEDDup.system" program

       - 2. Press S
	       Enter an output filename of up to 11 characters
	       The copy process is launched...

___________________________________________________________________________

Main screen commands

       - D/isk to file image
	       Enter an output filename of up to 11 characters
	       The application can guess the original file system.
	       Launch the copy process...

       - S/ave file
	       Enter an output filename of up to 11 characters
	       Launch the copy process...

       - O/ptions
	       Display the options menu...

       - ?/Help
	       Shall I really what that does?

       - CTRL-Q
	       Shall I really what that does?

___________________________________________________________________________

Option menu commands

       - B/its
	       Change timebits of nibbles (1 or 2). Default is 2.
	
	- C/hange original slot & drive
	       Select the slot & drive of your 5.25" disk controller card. Default is slot 6 and drive 1.

       - E/DD slot
	       Select a slot where your EDD card is in (default is 0 and means no EDD card)

       - F/ormat of diskette
	       If set, the application tries to find the file system of the diskette and
                sets the interleaving accordingly. Default interleaving is the DOS 3.3 one.

       - O/verwrite
	       If set, existing files with the same name will be replaced

       - P/refix
	       Display a destination folder menu, press:
	       - RET to push a prefix,
	       - TAB to change to next volume,
	       - ESC to pop a prefix,
	       - A to accept the current prefix.

       - S/tep
	       Select the arm step:
	       - 1.0 means every track (default)
	       - .50 means every half-track
	       - .25 means every quarter-track

       - T/racks
	       Select the end track of the diskette:
	               - $22 like a standard diskette (default)
	               - $23 means one extra track
	       Now, you can copy up to 40 tracks!

File formats

       The application saves different files on your disk drive.
        Please make sure you launch it from a 32MiB partition to save several disk images.
        If the program encounters an I/O error while saving, that will stop the copy process.

       - .EDD format
	       The most precise format. It contains data read from the 5.25" disk controller card before
                 the Logic State Sequencer performs its magic.
                That means that data are read at a bit-level, it is a "simple" set of 1s and 0s.
	       Each phase contains $4000 (16384) bytes.
	       A standard $22 diskette (step 1 track) is 573,440 bytes long. 

       - .NIB format
	       It saves nibbles as if they were read by the Logic State Sequencer,
                 therefore some protections may be lost (and I assure you they are)
	       Each phase contains $1A00 (6656) bytes.
	       A standard $22 diskette (step 1 track) is 232,960 byteslong.

       - .NIT format
	       It saves nibbles time cycle in a dedicated file.
                The default value of the timebit is $2.
                The different values are:
	               - $00 for 32 cycles nibbles,
	               - $01 for 36 cycles nibbles,
	               - $02 for 40 cycles nibbles.
	       Each phase contains $1A00 (6656) bytes.
	       A standard $22 diskette (step 1 track) is 232,960 byteslong.

       - .DSK, .PO formats
	       It saves standard 16-sec disks of DOS 3.3, ProDOS, Pascal and CP/M disks.
                The file extension is based on the operating system interleaving:
	               - .DSK for DOS 3.3 and unrecognized disks,
	               - .PO for ProDOS, Pascal and CP/M disks.

File sizes

       The combination of the Track and Step factors generates files of different file sizes.

Minimum System Requirements

       It is a 6502 compatible application and it requires a 80-column card.
	It has been tested on Apple IIgs ROM 01 & ROM 3 versions.

       There's 6KiB left for ADTPro compatibility ;-)
