The compatability of ADTPro and related programs is starting to get a little tricky. A goal of ADTPro is for the server to remain compatible with the vast majority of ADT and ADT-derived clients currently in use, while providing a superset of functionality in its own client. Below is some information about what capabilities lie where.
First of all, there are several pieces of software that are related in various ways. A quick survey of the major players:
| Program | Latest Client Version | Client Platforms | Server Platforms | Comms | Notes |
| ADTPro | 1.0.6 | II,+,e,c,GS,Laser | Linux, OS/2, OSX, Solaris, Windows (Java) | Serial, Uthernet, Audio | |
| ADT (Shipped with ADTPro) | 2.2 | II,+,e,c,GS,Laser | (ADTPro) | Serial (115.2k) | Nibble/half-track capable |
| ADT (Berlios) | 1.33 | II,+,e,c,GS,Laser | PC DOS, Windows | Serial (115.2k) | |
| A2V2 (Shipped with Virtual ][) | 2.1 | II,+,e,c | OSX | Serial (19.2k) | Nibble/half-track capable |
| MacADT | 1.21 | II,+,e,c | Mac OS9 and earlier | Serial (19.2k) |
Generally speaking, the client program (the part that runs on the Apple II) for any of these programs is compatible with the ADTPro server. Version 1.0.4 of ADTPro started shipping with a new offshoot of the original ADT client, based in part on the Berlios 1.33 version and in part on the A2V2-embedded version. The result is a superset of all the function that came with the latest Berlios ADT client, plus the nascent nibble/halftrack extensions from the A2V2 project. The intent is to have a highly capable client that can operate on the Disk II at a very low level as well as provide higher level support for generic ProDOS devices. That work is ongoing, so the landscape remains a little "busy" for the time being.
ADT version 2.2, included as ADT22.DSK in the ADTPro package, introduces nibble and halftrack disk extraction. Those capabiities are only present in the ADT client (i.e. the capability is not in the ADTPro client yet). The ADTPro server is capable of responding to the ADT requests, so in order to experiment with it, that is the combination of tools one would use.
Booting the ADT22.DSK disk image brings up the DOS ADT program:
From the main ADT screen, hitting the "S" key brings up a send sub-menu:
From the send sub-menu, you can choose to send normal ("Simple") sector-based images (i.e. .dsk, .po) to the server with "S", nibble-based images with "N", or half-track-based images with "H". Selecting "N" brings up the Nibble send window, where you enter the name of the nibble image to save at the host. Nibble images should be saved with the file extension .nib:
Alternatively, selecting "H" brings up the half-track send window, where you enter the name of the half-track image to save at the host. Half-track images, usable only with the Virtual ][ emulator, should be saved with the file extension .v2d:
The ADTPro server currently writes incorrect .v2d images - if you are going to be working with half-track images, you are best off sticking with the A2V2 server for the time being.
