Oct. 1st, 2012 - Jan, 5th,
2017 - 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 at version 2.2) is Brutal Deluxe's second answer to nowadays preservation of 3.5" and 5.25" diskettes on the Apple II.
We would like to thank Daniel Kruszyna (krue.net) for his artwork. Then, we would like to thank John Brooks for the 3.5" NIB code. Thanks to John, we can now preserve our 3.5" disks! Thanks also to 4am for his requests for improvements.
The main features of "i'm fEDD up" 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.
It supports quarter, half and full tracks!
- Nibble and timing preservation
It saves raw nibbles and their associated time cycles in separate files, for both 5.25" and 3.5" disks.
- 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.

.N35/.T35 file format
How to use? - 1. Launch the application Double-click the "imfEDDup.system" program - 2. To NIB image a disk, press S (5.25") or R (3.5") Enter an output filename of up to 11 characters The copy process is launched... ___________________________________________________________________________ Main screen commands - D/isk to file image This option create a .DSK or .PO disk image from an unprotected 5.25" floppy disk. Enter an output filename of up to 11 characters. The application can guess the original file system. Launch the copy process... - S/ave file This option creates .NIB/.NIT and .EDD/.FDI files from a protected or unprotected 5.25" floppy disk. Enter an output filename of up to 11 characters. Launch the copy process... - R/ip 3.5" disk This option creates .NIB/.NIT from a protected or unprotected 3.5" disk. It requires an Apple //gs, a boot from ProDOS8 (no GS/OS), 3MB of RAM, and a 3.5" disk in slot 5, drive 1. Enter an output filename of up to 11 characters. Launch the copy process... - O/ptions Display the options menu... - ?/Help Shall I really tell what that does? - CTRL-Q Shall I really tell 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) - (Guess) F/ormat of diskette If set, the application tries to find the file system of the diskette and sets the interleaving accordingly. The default interleaving is the DOS 3.3 one. - W/rite NIB files on disk By default, nibble files (.NIB) are written to disk. If turned off and if you have an active EDD card to rip your disks, only the .EDD files are stored. - N/IT files on disk By default, timing bits files (.NIT) are written to disk. If turned off, only the .EDD or .NIB files are stored. - 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, - CTRL-D to delete an unlocked binary file. - R/ead 3.5" again on error Sometimes, a 3.5" disk is not read entirely in memory. To prevent creating bad files, the option loops until the disk is reliably read. You can interrupt by pressing the ESC key. - 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! - E/X/port as By default, files are exported as EDD files. Press X to export a bitstream file as a FDI one. ___________________________________________________________________________ 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. - .FDI format The FDI format is similar to the EDD one in terms of bitstream. It has a header of $200 bytes and each phase is $4000 + 8 bytes long and is padded by $F8 zero bytes. - .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 bytes long. For a 3.5" disk image, the length of the file is 1,376,256 bytes long. - .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 bytes long. - .N35 format It saves nibbles as they are read by the Integrated Woz Machine on an Apple //gs. For a 3.5" disk image, the length of the file is 1,376,256 bytes long. Please refer to John Brooks' documentation for more information. - .T35 format It saves nibbles time cycle in a dedicated file. For a 3.5" disk image, the length of the file is 1,376,256 bytes. Please refer to John Brooks' documentation for more information. - .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 for 5.25" images The combination of the Track and Step factors generates files of different file sizes.

It has been tested on Apple IIgs ROM 01 & ROM 3 versions. There's 6KiB left for ADTPro compatibility ;-) ___________________________________________________________________________ Copyright Notice Parts of the source code (UP.EDD.S) are (c) 1986, Utilico Microware.
