ADT is the "Apple Disk Transfer" utility. Paul Guertin developed
ADT as a way to transfer
5.25" disk image files from PC directly to diskette on a
64k or larger Apple II and to send
5.25" diskettes to PC where they are saved as .dsk disk image
files. A typical ADT setup
is an Apple II with a serial card or built-in serial port
connected via a NULL modem cable
to a PC's COM port with each computer running ADT. For more
information, see the
FAQs and documentation included with most ADT distributions.
Tired of supporting old 8-bit technology with old 16-bit technology?
Enjoy at last the thrill of 32-bit technology, with the introduction
of ADTw! This Win32 port of the beloved Apple DiskTransfer utility
brings us at last to the 'modern era'. Forget about 'dropping everything'
and going into DOS mode to do image transfers. Now you can run the
PC side of ADT under Windows.
ADTw replaces only the DOS application-- i.e. the 'ADT program'
running on the PC. The Apple-side program is not changed.
ADTw Improvements include ...
+ You can task-switch
to another app, even minimize ADT,
while it continues working in the background.
+ Supports long file
names and lowercase characters, even on
the Apple side (if you have //e or greater).
+ Aborted .DSK files
(when ESC is pressed) are properly closed and
their file handles released (no more sharing violation errors).
+ Aborted .DSK files are padded with 00 instead of random bytes.
+ Don't have to hold
down any PC keys during "receive" operation.
(The author found that ADT for DOS running under Windows 95
would freeze unless he was holding down some key, even "shift")
+ Tested under Windows
95, but should theoretically work on all
32-bit Windows versions (NT, 98, 2000, ME, ...)
Alas, changing directories remains unsupported. You must still run
ADTw (i.e. adt.exe) from the target folder or establish a shortcut there.
For instance, if you want to transfer advgames.dsk to your Apple II, the
file advgames.dsk (and any other .dsk image files you wish to transfer)
should be moved or copied to the folder containing adt.exe. Similarly,
if you transfer a diskette to the PC, the .dsk file will be created in the
folder containing adt.exe.
Setting up and Using ADTw
After downloading ADT_2004.zip use WinZIP or an equivalent PC
utility to unZip the file-- the result is a folder named "ADT_2004"-- to
the place you want ADT to reside.
ADT_2004 includes both ADTw and the MS-DOS program for the
PC side as well as the three most popular Apple II-side programs:
version of PC-side program (ADTw) is adt.exe.
(by Sean Gugler)
version of PC-side program is now adtdos.exe.
(by Paul Guertin; ADT creator)
Apple II side
This is the original ADT (now at version 1.22). It is
intended for use on an Apple II equipped with Apple's Super Serial
Card (SSC) or a compatible card.
ref: ADTssc folder
dump file to transfer: adt.dmp or adtn.dmp
This is an adaptation of ADT (now at version 1.21) intended
for use on an Apple II equipped with the Apple Communications Card
and other, generally older, non-SSC cards.
ref: ADTcc folder
dump file to transfer: ADTcc.dmp
This is an adaptation of ADT intended only for transferring
disks from PC to an Apple IIgs. It uses the the built-in IIgs modem
serial port and firmware. (Version beta .91)
ref: ADTgs folder
dump file to transfer: adtgs.dmp
Users new to ADT will need to transfer one of the Apple II-side
ADT programs to the Apple II. How to do the transfer, setting up a
NULL modem connection, and more is discussed in the included
Text documentation files. Also see the comp.sys.apple2 Apple II FAQs
Telecom-1 page and feel free to ask questions on the newsgroup.
If you already have an Apple II-side ADT installed and running
well from a DOS 3.3 diskette, there is no need to change it.
The ADT_2004 distribution allows running ADT under Windows
or from the MS_DOS prompt. To start the new Win32 version ...
+ Double-click adt.exe
or run it from a Command Prompt.
Note: The files MFC40.DLL
and MSVCRT40.DLL are required for the
Win32 Edition of ADT. These files are bundled with Windows NT 4.0,
Windows 98, and later versions.
Windows 95 owners might see
error messages mentioning these files,
if they haven't been installed by any of the myriad other applications
that also require them. Technically, you should obtain them from
me, and though I can supply them by email I would greatly appreciate
it if you'd look for them on the web first. There are several sources. Try
Once obtained, copy both
files into your C:\WINDOWS\SYSTEM folder.
It should not be necessary to restart Windows.
+ About box is found through the system menu (icon on top left).
+ To use command-line parameters,
consider using a Windows Shortcut
instead of a batch file (.BAT). See Windows Help (Start Menu,
"Help" item) under the topic "shortcuts" to learn how to do this.
Actually, experienced ADT users can probably unZip the distribution
file and try out ADTw with barely a glance at the directions.
Plenty of enhancements are in the works, including support for .nib
nybble images and images using ProDos sector ordering (such as image
files created by Nulib). Full source code for several ADT applications is
included in the distribution file for those too impatient to wait.
