ADT
Apple Disk Transfer (ADT) transfers 5-1/4" diskettes and logical disk images between Apple II computers and the modern world. It is useful for people wishing to either archive original diskettes they own or for reconstituting logical disk images to physical diskettes on real Apple II hardware. Communications methods between Apple II and modern hardware is achieved with serial RS-232 connections.
ADT is an open source project hosted on Berlios.
Variants
The ADT server exists in MS-DOS, Mac OS, Unix, and Windows variants. The ADT client runs on Apple II hardware under the Apple DOS operating system. It is compatible with the Apple SUPER Serial card, the Apple IIgs modem port, the Apple IIc modem port, and the Laser 128 modem port.
An older version of the ADT client that has support for the Apple Serial Communications card (not hardware compatible with the Super Serial card) remains part of the distribution.
Lineage
Paul Guertin wrote ADT, deriving from Rich Williamson's SENDDISK program. The SENDDISK Apple-side program read an entire disk with Apple DOS' RWTS (Read Write Track Sector) routine, and transmitted the data through an Apple Super Serial Card in slot 1. The SENDDISK PC-side program listened to COM1 for such a data stream, and stored it in a .DSK file, the format expected by virtually all Apple II emulators.
The ADTPro project is an offshoot of ADT. ADTPro rewrote the ADT server to run under Java, expanding the scope of server support to Mac OSX and other Unix variants as well as OS/2. The ADTPro client, ported to Apple ProDOS, is able to transfer any storage device ProDOS can read, and is not limited to just 5-1/4" diskettes as ADT is.
