Apple Disk Transfer ProDOS (ADTPro) transfers diskettes and logical disk images between Apple ][-era computers and the modern world.

If you're familiar with the original ADT, ADTPro extends ADT's reach by working with more logical disk formats, drive types, communications devices, and host operating systems.

There is a host (server) component that runs on modern computers with Java, and an Apple II (client) component that runs on any Apple II compatible computer with at least 64k of memory.

ADTPro transfers disks using any of these communications devices:
· Super Serial Card, IIgs modem port or IIc serial port at 115,200 BPS
· Uthernet Ethernet card
· The Apple's cassette ports

ADTPro can be used to transfer either Apple diskette/disk images in DOS or ProDOS format. The Apple client side happens to run under ProDOS, but it is perfectly capable of reading or writing Apple DOS (or Pascal, or CP/M, or...) diskettes.

Server

The server program runs on a computer capable of running Java. Depending on how you want to connect to your Apple, you might also need a serial port and cables, an Uthernet card for your apple, or a couple of audio patch cables. The server offers a compact user interface that shows what communications are taking place between the host and the Apple.

The server's primary role is to send and receive disk images as requested from the client. But if you have recently acquired an Apple and a disk drive, and you have no software for it - you're in a bit of a tricky situation if you want to move software from the Internet all the way to your shiny new Apple. ADTPro's server can help get you get bootstrapped.

Client

The client side runs on the Apple ][. It handles most of the user interaction. When choosing disks/volumes to transfer, anything that ProDOS can see is fair game.

Transferring data occurs with a 20k buffer on the Apple, so all transfers are broken up into 20k chunks. A progress indicator shows how far it is into the current chunk, as well as a running count of the total progress.
