OpenBSD/pmax used to run on a large set of the Digital MIPS-based DECstation and
|
|
DECserver family. These machines were the counterpart of the <a

|

|
|
until the <a href="alpha.html">Alpha</a> line was ready.

<strong>The OpenBSD/pmax port was discontinued after the 2.7 release.</strong>

<h3 id="history"><strong>History:</strong></h3>
|
|
|
|
<p>
|
|
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.
|
|
|
|
<p>
|
|
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 any bugfixes, although releases were still being made.
|
|
|
|
<p>
|
|
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.
