== Operating Systems ==
 
 
 
The following Operating Systems can run on the MicroVAX II
 
 
 
=== VMS ===
 
Version 4.5 and higher can run
 
 
 
=== Digital Unix ===
 
[[Ultrix]]
 
 
 
=== CSRG BSD ===
 
*[[4.3 BSD]]
 
*[[4.3 BSD Quasijarus]]
 
 
 
=== NetBSD ===
 
Version 1.2 and higher of the VAX port of [[NetBSD]] can run on a MicroVAX II.  I've even built some instructions [[Installing NetBSD 1.2 on the SIMH MicroVAX II
 
|using SIMH]] on how to do so, that may be adapted to a real MicroVAX but I don't have one to test with.
 
 
 
=== OpenBSD ===
 
[[OpenBSD]] can run on the MicroVAX II as well, later versions are better for timing issues... 4.4 is the current good version.
 
 
 
== Emulation ==
 
  
The MicroVAX II is emulated in [[SIMH]].
