Download Software Demos.

All the BITS Mac OS software is available as downloadable demos. It was written by Robert Prior and is provided 'as-is'. Testing has been carried out on machines and OSes ranging from MacOS 7.01 on 68030 processors through to MacOS 10.3 under the Classic Environment on G4 processors. As the applications are require the Classic Environment, they will not run on the new Mac OS X Intel processor machines.

Full details on how to register the software is included in the application. There is no difference between the full software and the demos - just some disabled functionality like file saving.
