1.32 hugh 23: VAX has been a supported OpenBSD architecture since early 2000, when code was
24: synchronized with NetBSD's port. Being the second architecture to run BSD Unix
25: (in 1979!), it seems appropriate that these venerable vaxen should still have
26: a modern OS. The codebase is mostly from Berkeley, with contributions of free
27: code from Digital, Mt Xinu, NetBSD, OpenBSD and others. Development is ongoing,
28: and changes are shared among VAX hackers even to this day. The result of this
29: work is an Operating System that is stable and familiar to any OpenBSD user.

1.32 hugh 74: OpenBSD runs on a wide variety of VAX hardware, but our personal
1.18 hugh 75: <a href="want.html#vax">inventory of systems</a>
1.32 hugh 76: is limited. OpenBSD/vax may actually run on your machine even if it's not
77: listed here, and we rely on your testing and feedback to keep this list up
78: to date. After you finish installing your new system, consider running
79: "dmesg |mail dmesg@openbsd.org" to help us determine what types of
1.25 hugh 80: hardware people are using.
