OpenBSD/mac68k runs on many of the Motorola 680x0-based Apple Macintosh
computers.
It requires a Motorola 68020, 68030, or a 68040 processor. If you have a
68020, it will also need a Motorola 68851 PMMU (note that this is
different from the 68881, which is an FPU).
</p>
<p>
A mailing list dedicated to the OpenBSD/mac68k port is available at
<u><font color="#23238e">mac68k@openbsd.org</font></u>.
To join the OpenBSD/mac68k mailing list, send a message body of <b>"subscribe
mac68k"</b> to <a href="mailto:majordomo@openbsd.org">majordomo@openbsd.org</a>.
Please be sure to check our <a href="mail.html">mailing list policy</a> before
subscribing.
</p>
<p>
There is currently no maintainer for the mac68k port, although
Martin Reindl (<a href="mailto:martin@openbsd.org">martin@openbsd.org</a>)
hacks on it from time to time.
Others are definitely welcome to contribute!

<h3><font color="#0000e0"><strong>History:</strong></font></h3>
<p>
The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it
used to support most of the same hardware as NetBSD.
Development is ongoing, and updates from NetBSD are made from time to time,
depending on people's free time.
</p>
<hr>
<a name="status"></a>
<h3><font color="#0000e0"><strong>Current status:</strong></font></h3>
<p>
Currently, all hardware listed in the
<a href="#hardware">supported hardware</a> section below should boot
multi-user, and support enough of the on-board devices to be generally
usable.
</p>
<p>
A native, unaccelerated X11 server is available for built-in and NuBus
graphics.

<p>
<h4>Supported models</h4>
<p>
OpenBSD/mac68k runs on a large part of the 680x0-based Macintosh
computers.
The kernel itself has support for the following processor combinations:
<ul>
<li>68020 with 68851 PMMU and 68881 FPU
<li>68030 with 68882 FPU
<li>68040 (<b>not</b> including the 68LC040)
</ul>
<p>
The following Macintosh models are supported and tested.
This means that at least the SCSI controller, serial console and on-board
ethernet will function on these models.
On some of these machines, a full 68040 CPU is required to replace the
default 68LC040 CPU.
<ul>
<li>Classic family: SE30
<li>LC family: LC, LC II, LC III, LC III+, LC475, Performa 400-430, Performa 450, Performa 460, Performa 475, Performa 476
<li>Centris family: 610, 650
<li>Quadra family: 605, 610, 630, 650, 660AV, 700, 800, 840AV, 900, 950
</ul>
<p>
<h4>Supported devices</h4>
<p>
<ul>
<li>Internal SCSI controllers and peripherals:
<ul>
<li>Quadra/Centris series' onboard NCR 53c96 SCSI controller
(<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=esp&sektion=4&arch=mac68k">esp</a>).
<li>Macintosh II-series', Performa, and LC-series' onboard NCR 5380 SCSI controller

</ul>
<p>
<h4>Untested systems</h4>
The following Macintosh models are untested and/or lack support for major
subsystems. It is very likely that many of these system don't work at all.
<ul>
<li>Classic family: Color Classic, Classic II
<li>Macintosh II family: Mac II, IIx, IIcx, IIci, IIsi, IIfx, IIvi, IIvx, Performa 600
<li>500 family: 520, 550, 575, 580, Mac TV
</ul>
<p>
<h4>Unsupported systems</h4>
<ul>
<li>PowerPC-based Macs. Some of these are supported in the
<a href="macppc.html">OpenBSD/macppc</a> port.
<li>Powerbook family. Hardware capabilities limit the usability of these
systems.
<li>Machines based on the 68LC040 processor.
Unfortunately, the chip itself contains a major bug for which there is
no software workaround available in OpenBSD.
</ul>
<p>
<h4>Unsupported devices</h4>
<p>
<ul>
<li>Apple Communication Slot (CS) ethernet cards.
<li>Any other NuBus card not listed above.
<li>Floppy drive.
<li>IOP ADB subsystem on the IIfx, Quadra 900 and 950.
<li>IDE drives.
</ul>
