Apple Disk Transfer ProDOS is a feature-rich communications platform for exchanging disks and disk images between the Apple II and Apple /// family computers and the modern world.

ADTPro has two main purposes in life:

  • Transferring Apple disk images
  • Bootstrapping Apple II computers when boot diskettes are long gone
ADTPro uses any of three communications mechanisms:
  • Serial (RS-232, USB) hardware
  • A2Retrosystems "Uthernet" LANceGS Ethernet card
  • Audio/Cassette ports
Bootstrapping chores can occur with zero software at the Apple II end over serial and audio more...

Top Tool!!!
Works great with all my older Macs. From my SE models to my Performa's.

Version 1.2.1

This application comes at just the right time for me.

I hope this version ( 2.0 ) really works since I am in the process of going back in time to bring back to life and use my Performa 6360 and some other "legacy" Power Macs that do not deserve to rest in peace in our city dump or city recycle depot.

Even without having the full opportunity of trying this application I give it top marks for giving me encouragement to revive my Macs.

The intel/unix world is great although the legacy macs made that possible and even some midi/audio programs were obviously too tough to code into the intel world or when they were many excellent features were left behind.

Thanks to the people that made this application possible.
