A MicroVAX II

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

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.
