This article is from the Apple II Csa2 FAQ, by Jeff Hurlburt with numerous contributions by others.
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. ---------------------------- By: Paul Guertin, Sean Gugler, Paul Schlyter, Rubywand, Ronny Svedman 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 program 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 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. ---------------------------- By: Delfs 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. By: Rubywand
