ADTPro 1.0.1

Apple Disk Transfer ProDOS (ADTPro) transfers diskettes and logical disk images between Apple ][-era computers and the modern world.
If youre familiar with the original ADT, ADTPro extends ADTs 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 Apples 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 servers 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 - youre in a bit of a tricky situation if you want to move software from the Internet all the way to your shiny new Apple. ADTPros 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.
Main features:
- Compatibility with any device ProDOS can read
- Compatibility with any Apple ][ (or clone) computer with 64k memory
- Compatibility with many logical disk image formats: .DSK, .PO, .NIB, 2IMG
- Server compatibility with original ADT client program
- Server compatibility with Windows, Mac OSX, Linux, and probably Solaris
- Ability to bootstrap an Apple ][ from bare metal over serial or cassette ports
- Ability to send floppies in batch mode without having to name each one
Enhancements:
New functionality:
- [Client] The formatting function is now integrated instead of being a separate program
- [Client] Volume picker screen sets the default slot/drive for the BASIC interpreter
Bug fixes:
- [Client] (Finally) fixed audio transfer retry logic - darn Java and its signed bytes! Audio transfers are reliable at last. Slow as ever, but reliable.
- [Client] Fixed 15-character volume name bugs: one in the formatter, one in the online displayer/picker
- [Client] Made the Uther slot-scanning algorithm a little less intrusive, and used a MHz-insensitive timing loop to make UDP timeouts a little more reasonable on accelerated machines
- [Client] Used a MHz-insensitive timing loop to make the delightful beeping noise sound the same no matter how fast the CPU is going
- [Server] Better flow control for serial bootstrapping - improves life for serial interfaces that do their own buffering (i.e. Keyspan USA-28)
