35: The pmax port of OpenBSD was started by Thomas Graichen shortly before the
36: OpenBSD 2.0 release, based on the NetBSD/pmax sources. It was then slowly
37: brought in shape, becoming self-hosted, and moving to ECOFF, then ELF
38: binaries.
1.15 graichen 39:
1.34 miod 40: <p>
41: A few releases later, Thomas Graichen stopped working on this port, and
42: nobody stepped in. The port was slowly left in oblivion, with no new code and
1.41 deraadt 43: hardly any bugfixes, although releases were still being made.
1.15 graichen 44:
1.34 miod 45: <p>
46: A timid effort was made after the 2.7 release to revive the port, but
47: MIPS-specific toolchain problems prevented the system from building itself for a
48: long time, and development went on hiatus again. When the problem was finally
49: fixed, it was decided however to stop supporting it and remove the code from the
50: tree.
