Logging into a 4.7 BSD system
Creator: Digital Equipment Corporation
This Version: 7.3 (for VAX)
8.3 (for Alpha and Itanium)

VMS is a high-end, secure, multitasking operating system written by Digital Equipment Corporation and currently actively maintained by Hewlett Packard.

It runs on the VAX, Alpha, and Itanium platforms. As of the Alpha platform, the OS was redubbed 'OpenVMS'.

Emulation

VMS and OpenVMS can be run on SIMH's VAX emulation. Although VMS is still a commercial operating system, just like many varieties of commercial UNIX and Windows, HP (which is the current owner of DEC's assets) has a hobbyist program which allows licenses to be obtained for non-commercial uses. See the following:
