ADTPro

Apple Disk Transfer ProDOS (ADTPro) transfers diskettes and disk images between Apple II-era computers and the modern world. There is a host (server) component that runs on today's computers with Java, and an Apple (client) component that runs on any Apple II or Apple /// compatible computer with at least 64k of memory.

ADTPro transfers disks using any of these communications devices:

ADTPro has these features:

  • Transfers any storage device ProDOS or SOS can access
  • Runs on any Apple II, Apple ///, or compatible with 64k of memory
  • Runs on Linux, Mac OSX, OS/2, Windows, and probably Solaris
  • Understands many digital disk formats: .DSK, .SDK, .SHK, .BXY, .PO, .DO, .NIB, 2IMG
  • Understands many physical Apple disk formats: DOS, ProDOS, SOS, Pascal, CP/M, among others
  • Serves the original ADT client as well as the ADTPro client
  • Bootstraps Apple II and Apple /// computers from bare metal over serial or cassette ports
  • Sends floppies in "batch" mode without having to name each one
  • Formats blank disks
  • Serves a virtual drive as slot 2, drive 1 on the Apple II and .VSDRIVE on the Apple ///

The latest ADTPro can always be downloaded from the SourceForge project page.

Bootstrapping the Apple II or Apple ///

If you already use the DOS version of ADT, you can use it to transfer the disk image containing ADTPro that comes with this project (ADTPRO-1.3.0.DSK) to your Apple. Reboot the Apple with the ADTPro floppy, and you're ready to go.

If you don't use DOS ADT now, don't have software for your Apple yet, or don't have a serial card, more bootstrapping scenarios and configurations are detailed below.

If you still need to connect your host and Apple computers with physical cables, refer back to the "Connections" section for your connection type:

Demo Presentation

Attached below are slides to a brief demonstration presentation I gave to a local Mac users group. It goes through the basic steps it takes to bootstrap the Apple II. There are speaker notes, and it contains a few resources and links.
