.nib Images to real Apple disks
Jose Carlos Lord Apple
My name is Jose Carlos (Brazil) and I'm new in this group.
I'm trying to convert a .nib image to a real disk, but without success
!!! How can I do to transfer a .nib image to a real disk ? MUst I need
another soft than ADT ?
Thanks, and sorry by my bad english !!

José,
You need a program called SST - Super Saltines Transcpy - which you can
download from Asimov and ADT over to your Apple 2.
See Rubywand's excellent Csa2 FAQs :
http://home.swbell.net/rubywand/Csa2T1TCOM.html
Here are some of my notes on this subject .... (I am creating a concise
document on this and other topics for the Apple 2 section on my WEB page).
****************************************************
Transferring Copy Protected Disks : Apple 2 -> PC
****************************************************
Execute SST - Super Saltines Transcopy on the Apple 2 :
Select Menu Option 1 - Pirate a Disk
Select Menu Option 2 - Pack
Enter the Start Track - 0 is the default - just hit enter to keep this
value.
Enter the End Track - 34 is the default - just hit enter to keep this
value.
Step - 1 is the default - just hit enter to keep this
value.
Synchronize Tracks - NO is the default - just hit enter to keep this
value.
Nibble Count - NO is the default - just hit enter to keep this
value.
Now you are told to insert disks, and press <Return>.
So, place the Copy Protected Disk into Drive 1 on your Apple 2 and a blank
DOS 3.3 formatted disk into Drive 2, and press <Return>.
SST will then read the copy protected disk and write this in packed,
transferrable
format onto the standard DOS 3.3 disk in Drive 2.
Only half of the image of the Copy Protected Disk can fit onto the blank
disk in Drive 2, so at the half-way point, SST will ask you to place another
blank formatted disk into Drive 2.
Do, this, and press <Return> and SST will complete the process.
Now, you have a 2 standard DOS 3.3 floppy disks that each contain half of a
complete image of a Copy Protected Disk.
These Disks can then be transferred to the PC for use with emulators using
ADT,
in exactly the same as we transferred Standard Floppy Disks above. (See
"Transferring Standard Floppy Disks" above).
On the PC side - where you are running an Apple 2 emulator - you will need
to use SST (running on an Apple 2 Emulator) to stitch the 2 halves of the
Copy Protected Disk's disk images back together again.
Let's say you transfer the 2 standard disks as "d1.dsk" and "d2.dsk", we now
need to UnPack these disks from within the Apple 2 Emulator on the PC to a
special NIB disk image file (you could copy and overwrite an existing NIB
file, or else download and use the blank.NIB file from Asimov - I'll assume
you have called the NIB file "game.nib" on the PC) :
Select Menu Option 1 - Pirate a Disk
Select Menu Option 3 - UnPack
Select Menu Option 1 - Packed Parms
Enter the Start Track - 0 is the default - just hit enter to keep this
value.
Enter the End Track - 34 is the default - just hit enter to keep this
value.
Step - 1 is the default - just hit enter to keep this
value.
Synchronize Tracks - NO is the default - just hit enter to keep this
value.
Nibble Count - NO is the default - just hit enter to keep this
value.
Place d1.dsk in drive 1 and game.nib in drive 2, and hit <return> to make
SST proceed.
Then, when prompted to "turn over the disk", place d2.dsk in drive 1 and
leave game.nib in drive 2 and hit <return> and SST will finish the process
of rebuilding a virtual disk image copy of the original copy protected
floppy disk.
You should then have a NIB disk image file that contains the copy protection
/ formatting
information of the original disk along with all of the program code / data
from this disk, and this disk should now run under emulation just as the
original floppy disk runs on a real Apple 2, only it will be considerably
faster under emulation.
****************************************************
Transferring Copy Protected Disks : PC -> Apple 2
****************************************************
You can reverse the above process to transfer NIB disk images back to real
floppy disks on the Apple 2. To d this, you would use SST on the Apple 2
emulator to pack the NIB disk onto two .DSK disk image files, ADT these
across onto 2 floppy disks on the real Apple 2, and then use SST on the real
Apple 2 to unpack (stitch) these together again onto a single floppy disk.
Hope this is useful.

I did this with the .nib image "Might and Magic II" (got on ASIMOV),
but after the end of the process, the single floppy does'nt work !!!!
Why ? I did this:
1- On Emulator, using SST, I made 2 .dsk files
2- Using ADT I transfer the 2 .dsk to 2 single floppys (DOS 3.3
formatted)
3- On real Apple //e, using SST, I unpack this 2 floppies into a
single floppy disk, The SST finish withou any error !!! But, whaen I
try to boot with this disk, it doesn't work !!!!
Whay am I doing wrong ?
Thanks and sorry by my bad english !!!!

Don't know. Sounds like a pretty good process.
Some possible problems are ...
o- When you made your images on the PC, you used one or two .dsk images
which were in ProDOS order. These are rare; but, there are some. (ProDOS
order disk images are usually .po files.)
As far as I know, ADT does not try to check the sector ordering of
a .dsk image. So, a ProDOS ordered image with a name ending in ".dsk"
might well be sent and end up mixed around when written in DOS 3.3
order on the target diskette.
o- There are several .nib images in the M&M II set. I'm pretty sure that
Only the first image (Disk A) is bootable. If you sent one of the other
images, it probably would not boot.
o- M&M II requires an enhanced //e (or later model) Apple II. If your //e
does not have 128k or if it can not display double-hires, the boot disk
may hang during booting.

I need 2 ProDOS images before use SST ?

I got the first one.

No. DO3 3.3 order images are correct.

I tried the same process you used. When using SST on AppleWin to
convert the first MM2 .nib to disk images, I got READ errors on SST for
every track. (SST shows an "R" instead of a "." for each track.)
Also checked SST running on Apple Oasis. Got READ errors again.
Evidently, you can not use SST to convert a .nib image to .dsk
images. (Was a neat idea; but, looks like it doesn't work.)
What we need is a utility which will convert .nib to diskette on
the Apple II.

has to be recoded in several areas, to work like this:
For each of the 35 (or whatever) tracks do:
1. On the PC: chop off one track from the .nib disk image
2. Transfer the nibble contents of that track to the Apple II
over the serial port
3. On the Apple II: call RWTS to move the head to the appropriate
track on the target diskette
4. On the Apple II: write the nibbles to the diskette
Unfortunately I cannot write this code myself, since I no longer
have a working 35-track Apple II floppy drive.... (fortunately I
transferred my Apple II diskettes to .dsk images before this drive
failed).
To do 4. properly is the hardest part, but here I can contribute
some code, reverse engineered from an early version of Locksmith and
then adapted to run on its own: it simply takes a buffer of nibblized
data in the Apple II RAM and writes it to the disk, one full track.
Timing is critically important here; that's why this code is hard to
write.

But, what software we must use ?
Jose Carlos
no...@nowhere.net
to take that code and apply it to ADT and make ADTSST, a new program
that transfers nibblized tracks instead of sector data? I do not
believe I have the skill unless I can get hold of ADT source code.
on the Apple II side
1. Read and analyze track with EDD code
2. Transfer Track to PC
3. Write track to NIB file.
and on PC side
1. read nib image track
2. Transfer to Apple II
3. Write & verify track with EDD code
Any takers?
Thankx,
Ed

Modify the EDD program to write the track data to NIB image file on a
ProDOS media. This would require one to create a ProDOS program that
reads tracks using the bit routines in EDD and writing to a file using
the ProDOS API.
Thankx,

ISTR that Bag of Tricks contains code to write whole nibblized tracks
to disk, too. In fact, I think that the source code to do it is contained in
the accompanying book (or was it Beneath Apple ProDOS?).
I would be very interested in seeing the EDD source.

ADT is open source -- the source code is supplied in the standard
adt122.zip archive.
I also have a copy of the EDD source and almost wrote the program
you're thinking of writing, but sadly I have little time to dedicate
to hobby programming anymore.
