The pmax port of OpenBSD was started by Thomas Graichen (graichen@OpenBSD.org) shortly ! before the OpenBSD 2.0 release. It is currently without a maintainer. ! If you would like to maintain the port, hardware is available so please ! send mail. ! From the pmax specific code it is heavily based on NetBSD/pmax. ! I want to take the chance ! here to say thanks to Dieter Mayer and Rob Urban for supplying me (Thomas) with ! the hardware to do the development on. Also i want to thank all the people ! from the NetBSD/pmax team and mailing lists especially Jonathan Stone ! and Michael Hitch for their help in many situations. ! If you are interested in getting OpenBSD/pmax you can either use the latest ! formal release of OpenBSD or one of the snapshots of OpenBSD/pmax if you ! are interested in tracking the current state - you may get them both from ! the usual OpenBSD ftp servers.
!Despite of the fact that the hardware specific code in OpenBSD/pmax ! doesn't differ much from NetBSD/pmax, ! you get all the usual OpenBSD improvements, additions and fixes - most ! important here are the security related stuff and fixes. !
OpenBSD/pmax currently supports the following machines:
!OpenBSD/pmax does currently not run on:
!Per Fogelstrom (pefo@OpenBSD.org) ! now also has one of the r4000 cpu upgraded decstations ... so i expect ! support for them sometime in the future.
! !If something is wrong here - please let me know!
! !Framebuffer:
! !Keep in mind that you need a monitor which can do sync on green- because ! all the above framebuffers give sync on green output. Also the monitor ! should be multisync-capable or it should have a dec-compatible fixed frequency. ! All the above framebuffers should be supported by the x server too.

! OpenBSD/pmax runs on a large set of the Digital MIPS-based DECstation and ! DECserver family. These machines where the counterpart of the VAX-based VAXstations, ! until the Alpha line was ready. !
!! The OpenBSD/pmax port has been ! discontinued after the 2.7 release. !
!! There is currently no one working on bringing this port back to life. ! The source code is still available in the CVS Attic, and code can be found in ! NetBSD as well. ! If you are interested in reviving the pmax port, make it work and contact ! Todd Miller and ! Miodrag Vallat. !

+ !! The pmax port of OpenBSD was started by Thomas Graichen shortly before the ! OpenBSD 2.0 release, based on the NetBSD/pmax sources. It was then slowly ! brought in shape, becoming self-hosted, and moving to ECOFF, then ELF ! binaries. !
!! A few releases later, Thomas Graichen stopped working on this port, and ! nobody stepped in. The port was slowly left in oblivion, with no new code and ! hardly bugfixes, although releases were still being made. !
!! A timid effort was made after the 2.7 release to revive the port, but ! MIPS-specific toolchain problems prevented the system from building itself for a ! long time, and development went on hiatus again. When the problem was finally ! fixed, it was decided however to stop supporting it and remove the code from the ! tree. !

! The last supported OpenBSD/pmax release has been ! OpenBSD 2.7. ! It is not available on ftp sites anymore, but releases up to 2.3 were ! available on CD. !
