Oct. 1st, 2012 - Apr, 19th, 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 2.3) 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. Thanks to John Brooks for the 3.5" NIB code. Thanks to Brian Wiser and 4am for their requests for improvements. Thanks to a2heaven.com for their RamWorks 8MB memory card.

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.

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.

Minimum System Requirements

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

There's 4KiB left for ADTPro compatibility ;-)
