'''VAX''' is the name (short for 'Virtual Address eXtension') for a family of computers from [[Digital Equipment Corporation|DEC]]. They were the successors to the [[PDP-11]] series of [[minicomputer]]s.

==Operating Systems==

The following Operating Systems are known to run on the VAX.

*[[VMS]]
*[[Unix/32V]]
*[[BSD]]
*[[Ultrix]]
*[[NetBSD]]
*[[OpenBSD]]
*[[OracleDB]]

==Diagnostic Software==

There are two kinds of diagnostic software for VAX computers:

* [[MicroVAX Diagnostic Monitor]] for all [[MicroVAX]] computers (except for the [[MicroVAX I]])
* [[VAX Diagnostic Supervisor]] for all other VAX models

==Simulators==

There are 2 well known simulators for the VAX:

*[[SIMH]]
*[[CharonVAX]]

==New Emulator Hardware==

* [[UniBone/QBone]]

==Russian Clones==
