VMS is a high-end, secure, multi-tasking operating system written by Digital Equipment Corporation and currently actively maintained by VMS Software, Inc. (VSI).

It runs on the VAX, Alpha, Itanium, and x86 platforms. Beginning with VMS V5.5, the OS was renamed to OpenVMS.

VMS has been ported to x86 by VMS Software, Inc..

Emulation

VMS and OpenVMS can be run on SIMH's VAX simulators. OpenVMS can also run on ES 40 Emulator which will run the Alpha version. Although VMS is still a commercial operating system, just like many varieties of commercial UNIX and Windows, VMS Software, Inc. (which is the current owner of most of DEC's assets) has a hobbyist program which allows licenses to be obtained for non-commercial uses for the Alpha, Itanium, and x86 platforms.

There are currently no known hobbyist licenses for OpenVMS/VAX versions V5.x and higher.
