Apple II Disk Transfer

It seems that others have also had the desire to upgrade the ADT (Apple Disk Transfer) tool to work with disks other than the Disk II 5-1/4 inch floppy format under DOS 3.3.

ADTPro is a ProDOS-based version of ADT. It should presumably work with all block devices recognized by ProDOS. I e-mailed some code to David Schmidt which allowed ADT to work with the ordinary IIgs serial ports; direct access to the Z8530 chip might allow for faster transfers; that’s a potential project.

    …And that code grafted perfectly well into the ADTpro base. Time to write an interrupt handler/buffer manager that will interoperate with ADT’s ancient polling interface.
