OpenVMS simh 1

OpenVMS is an operating system originally developed by DEC (Digital Equipment Corporation), a company acquired by Compaq which was then acquired by HP for the VAX platform.

Although development started in the mid-1970s into the 1980s, OpenVMS is still very much alive with up-to version 7.3 available for VAX, and continued development in 8.x for DEC Alpha and now Intel Itanium architectures. Even Oracle, who acquired DEC's Rdb RDBMS have stated that they will continue to support and develop Rdb, creating a lesser gap between it and Oracle Database system
