Desk and Max are both desktop interfaces, where you can launch, copy and do other commands using your mouse instead of typing commands. All with icons an symbols and point and click.
Desk was (i believe) the first version released and was based on a disc.
Later Max was created and was on a ROM. This gave the advantage you could call Max just by pressing F8+BREAK (DFS) or F9+BREAK (ADFS) combination.

Extra! is literally what the title says. This software was released on 2 discs (40T) and has several extra programs to the AMX Stop Press package. It gave the possibility to preset your pages disc so you would not have to put in the system disc to launch Stop Press. It also gives extra printing stetting options and colour setting and much more.
It also has loads of extra Fonts and Clip-Art.
As far as I know their has been only one release of the software.

Page Maker (later Stop Press) is, if I'm right, the software package where AMX was famous for.
This is a fully WYSIWYG DTP software bundle and all operated with a mouse using point and click.
The bundle came with a view discs and 2 ROMs.
The discs included the system startup software and fonts. (later I believe the ROMs where on the disc as images and could be loaded in the SWR for use)
Both PageMaker and Stop Press always need a real DFS disc for the pages you are editing. The system disc or other utilities can be run from another device, like ADSF hard drive or RFS. Did not yet figure out how to fool the software.
Page Maker is only on 2 ROMs. The mouse drivers are included in the support ROM from PageMaker itself. So there is no extra Mouse Support ROM needed.​

AMX (Super) Art is the mouse driven drawing software. The versions 1 and 2 are the monochrome versions, working in MODE4. Also the art software was given on disc, and the mouse drivers where on ROM. Later the Art software was also included in the ROM and was the disc only needed for extra functions within the Arts software.
Versions 3 and later where the colour versions and worked in all graphical modes of the BBC.
All versions had the possibility for the user to use the Mouse software in their own BASIC programs.

AMX Utilities is a software package for people who had a mouse and the AMX support ROM. On the disc there where some extra utilities for the AMX mouse including AMX Art 2 (MODE 4 only), Sketch (a MODE 2 drawing program), Utilities for the Art program and some other extras.
Comparing to the AMX Art V2.1, mentioned above, this software package had more then only AMX Art.

This program needs a support prior to V3.41. This because from version 3 the ART software was on the ROM. Below you can find all you need to run the Utilities and programs.
