! OpenBSD/amiga runs on the Amiga machines manufactured by Commodore.
! It requires a Motorola 68020 or better processor, with an external Motorola
! 68851 PMMU in case of a 68020.
! This leaves out models 500, 600 and 1000 which can not receive accelerator
! boards.
!
! The OpenBSD/amiga port has been
! discontinued after the 3.2 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 amiga port, make it work and contact
! Niklas Hallqvist.
!
! The OpenBSD/amiga was initially derived from NetBSD/amiga in 1995, and
! used to loosely track the NetBSD changes until 1998. Niklas Hallqvist also
! wrote a new interrupt remapping system, improving average performance,
! revamped the installation media, and ported the ISA bus support to a
! big-endian platform, for GoldenGate II and CrossLink cards.
!
!
! After a few years, due to the lack of users, this port was slowly left in
! oblivion, although releases were still being made. Eventually, it was decided
! to stop supporting it and remove the code from the tree.
