                     49: In September 2003, Chris Tribo published some excerpts of the technical
1.10      miod       50: documentation for the AViiON series 400. From a cursory glance at it, it was
                     51: obvious these systems were built upon a modified MVME188 design, which was
                     52: already supported by <a href="mvme88k.html">OpenBSD/mvme88k</a>, but there
                     53: was no interest in AViiON support at that time.
1.1       miod       54:
                     55: <p>
                     56: Then, late April 2006, enough boredom convinced Miod Vallat to start a port,
1.10      miod       57: even though he did not have access to any AViiON hardware, as a challenge.
                     58: In two weeks, thanks to the help of Chris Tribo, a model 410 was running
                     59: multiuser (but diskless) - a proof that this effort was worth continuing
                     60: inside the OpenBSD tree.
                     61: <p>
                     62: Work on the port has continued since then, adding support for the 4600/530
                     63: family, as well as multiprocessor support. The port was left staging until
                     64: the effort to switch all m88k ports towards the ELF binary file format and
                     65: shared library paid off, from autumn 2012 to winter 2013.
                     66: <p>
                     67: The port eventually became self-hosting on a dual-processor 4600 model in
                     68: october 2013, with the first working (i.e. recognized by the PROM) boot blocks.
                     69: <p>
                     70: And work continues...
