This article is from the Apple II Csa2 FAQ <http://stason.org/TULARC/
pc/apple2/faq/index.html>, by Jeff Hurlburt with numerous contribu-
tions by others.

20.003  I've heard of ADT and ap2222pc.  How do these packages work 
for transferring Apple II disks between an Apple II and a PC?

     Yesterday I downloaded ap2222pc.zip written by some guy in Hong 
Kong.  It copies whole Apple disk images over to the PC, or PC to 
Apple, or individual files back and forth!

     You buy a 25-pin male parallel port connector and two 8-pin DIP 
sockets from Radio Shack.  He gives the wiring diagram for connecting 
9 wires between them.  You type in a 6502 assembly program on your 
apple at address 300.  Save the program, shut things off, hook up the 
wire from your PC printer port to the Apple Game Controller socket, 
turn them on (Apple first, then the PC), and run his programs.

     It works great!  I've already made 26 disk images from my old 
Apple disks.

     ADT (Apple Disk Transfer) lets you transfer 5.25" 16-sector A2 
disks from your Apple II to your PC.  It will also transfer standard 
5.25" .dsk disk image files from the PC to a formatted 5.25" diskette 
on the Apple II.  The connection is a fairly simple NULL modem link 
between serial ports using standard cables and adaptors.

     Transferred disks can be DOS 3.3, ProDOS, Pascal, ....  However, 
ADT will not correctly transfer most copy protected disks to the PC; 
and, it will not transfer ProDOS-order (usually .po) disk image files 
to the Apple II.

     ADT is a pair of dedicated telecom transfer programs--one for 
Apple II running under DOS 3.3 and one for the other computer (almost 
always a PC; but, there is also a version for Mac).  The PC-side pro-
gram is available in a vesion for Windows 95, 98, Me (adt.exe) and one 
for MS-DOS (now named "adtdos.exe").

     There are several versions of the Apple II-side program in order

[to] fit different models and serial interfaces:

ADTssc--The current version (1.22) of 'standard ADT'.  It requires 
that an Apple Super Serial Card or compatible card be installed or 
that the Apple II be a // c or IIc+ (which have SSC-compatible serial ports).

ADTcc--ADT modified to work with many, mostly older, non-Super Serial 
Card serial interfaces.  (Current version is 1.21.)

ADTgs--Currently at v.91, this is ADT modified to work with the IIgs 
modem port.  (ADTgs will, at present, do only PC-to-Apple II disk 
image transfers.)

     ADT is practically always distributed as a .zip file including at 
least an Apple II and PC program plus directions for transferring the 
Apple II program dump file to your Apple II, setting up, and 
operation.

     The latest distribution, ADT_2004.zip includes the three Apple 
II-side programs, both PC-side programs, directions, and assorted 
support files.

     Each Apple II-side program is a block of code (e.g. adt.dmp) 
designed to be dumped from PC to an Apple II running DOS 3.3 via a 
simple Text transfer to the monitor which requires no terminal or 
other special software on the Apple II.

     Once both sides are installed, ADT transfer speed typically 
ranges from 9600 baud through 19,200 baud.

     If you find you just can't get your communications software to 
transfer that ADT file, then lets try it without any comm software at 
all.  We will still essentially make the IBM type in the program on 
the Apple II using the comm ports of both computers.

     This procedure will require an Apple Super Serial Card and the 
ADT and DOS files on your PC.  This instruction sheet requires that 
you have downloaded the PC version of ADT and uncompressed it in a 
folder on the C: drive.

Note: This procedure may be modified to work on a IIc or IIc+ computer 
as they have SSC compatible hardware built in, the trick is getting

the cable wired correctly.

For the Apple Computer --

1. Turn off your Apple II computer, take the lid off and rub the power 
supply box 3 times for luck.  (And to dissipate any static electricity 
on your person.)

2. Set the SSC card for 300 baud.  Switches are as follows 0=off=down, 
1=on=up 1001111 - 1101110

Just left of the rainbow colored cable there is a 'chip' with a 
triangle on it.  Make sure the triangle points towards the top of the 
card.  If it does not, lift the chip out of it's socket and turn it 
around.  This chip is a jumper block.

Note: You can use a standard modem cable between the SSC and your 
Windows computer instead of a null modem cable if you change the SSC 
jumper to point down instead of up.

3. Place the SSC card into slot two of your Apple II.

Note if you use a IIgs: Go into your IIgs control panel and set slot 
two to 'your card'.  Press OpenApple-Control-Esc at the same time to 
enter the control panel.  Make sure to press 'Enter' to leave a menu, 
NOT Esc.

4. Plug in the cable to both computers.  (Properly wired cable is the 
key.)

For the WinDoze Computer --

5. Uncompress the ADT122.zip into a folder with the name adt122 on the 
root of the C: drive for convenience.  (I use Winzip for ease of use.)

6. Boot up a DOS disk and get to a DOS prompt.  For a Windows 95/98/ME 
computer, use a 'dos window' by selecting Start/ Programs/ MSDOS 
Prompt.

7. Set up the port for communications.  Type in the following command 
at the dos prompt, replace the X with a port number, 1 or 2 where the 
cable is plugged into the PC.

mode comX baud=300 data=8 stop=1 parity=n

Now --

8. Turn on the Apple IIe and boot up a DOS 3.3 disk and type the 
following command.

IN#2

Note: If you do not have a DOS 3.3 disk, you can create one by sending 
the DOS33 file instead of the ADT file, using these instructions to 
transfer the DOS33 file, then following Rubywand's instructions on 
making a bootable disk.  (Took a really long time to transfer DOS33 at 
300 baud before I could send the ADT program.)

9. Go back to your Windows machine and type this into your Dos Prompt 
window.  The first two lines move to to the folder where you have the 
ADT files.  Then the third line starts typing the file on the Apple 
II.  Replace the X with the port number, 1 or 2 as you did above.

cd \adt122 TYPE ADT.DMP>comX

10. You will see the ADT program being typed in by your PC.  It will 
even save itself to the disk before it is all done typing.

11. Once you have ADT on both computers, you should set the SSC to 
19200 baud and work from there using the ADT program to transfer 
standard DOS33 and ProDOS disks.  The SSC card switch settings are as 
follows for 19200 baud.  0000111 - 1101110

     I have verified this procedure several times and had no problems.   
Just remember to do the IN#2 on the Apple before you do try and 
transfer the file.
