Hobbyist License

The Student Hobbyist License program allows non-commercial use of the latest version of OpenVMS on the FreeAXP Alpha emulator. The disk image that you load on the emulator comes preloaded with the OpenVMS operating system and licenses, so it is ready to run. All changes that you make to your pet system are saved, so you can play with it until the license expires and then back up your files and restore to the new updated system easily. The hobbyist kit includes popular compilers.
