About NetBSD/pmax
NetBSD/pmax is the port of NetBSD to Digital Equipment
Corporation's MIPS based computers. NetBSD/pmax runs on
wide range of DECstation and DECsystem family. NetBSD/pmax
is the first port which can run on either MIPS R3000
processors or MIPS R4400 processors; single kernel can run
common set of user programs.
Development activity on NetBSD/pmax continues at a speed
depending of people's spare time. NetBSD/pmax developers
are making efforts on extending hardware supports to models
which NetBSD/pmax does not support this moment.
Easily installed binary distributions of NetBSD/pmax are available for
the 2.0 release and for
snapshots of NetBSD-current.
