OpenBSD/mac68k
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).
A mailing list dedicated to the OpenBSD/mac68k port is available at
mac68k@openbsd.org.
To join the OpenBSD/mac68k mailing list, send a message body of "subscribe

There is currently no maintainer for the mac68k port.
Table of contents
History:
The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it
used to support most of the same hardware as NetBSD.
Although this port is still being supported, there has been no effort
to catch up with recent NetBSD developments.
Current status:
Currently, all hardware listed in the
supported hardware list section below should boot
multi-user, and support enough of the on-board devices to be generally
usable.
Supported hardware:
Supported machines
OpenBSD/mac68k now runs on a large part of the 680x0-based Macintosh
computers.
The kernel itself has support for the following processor combinations:
- 68020 with 68851 PMMU and 68881 FPU
- 68030 with 68882 FPU
- 68040 (not including the 68LC040)
The following Macintosh models are ``fully'' supported.
This means that at least the SCSI controller, ADB (keyboard and mouse), and
some sort of display will function on these models.
On some of these machines, a PMMU and/or FPU are required as they are not
provided by default with the machine.
- Macintosh II family: II, IIx, IIcx, IIci, IIsi, IIvx, IIvi
- Classic family: Color Classic, Classic II
- Centris family: 650
- some models of the Duo series
- LC family: 520, 550, LC II, LC III
- Performa family: 4xx, 600
- Powerbook family: 140, 145, 145B, 160, 165, 165c, 170, 180, 180c
- Quadra family: 610, 650, 700, 800
- WGS (Workgroup Server) series: 80
- SE/30
- MacTV
Supported devices
- Internal SCSI bus and most SCSI tapes, hard drives, and cdrom.
- Internal sound.
- Most NuBus video cards
(there have been some problems with some 24-bit color cards).
- Both internal serial ports.
- ADB keyboards and mice
(adb).
- Ethernet cards based on the Natl. Semiconductor 8390 (Asante, Apple, and a few others)
(ae).
- Quadra/Centris AV series' onboard MACE ethernet.
(mc).
- Some ethernet cards based on the SONIC chip including internal Ethernet on many of Apple's non-AV Quadras/Centrises and PowerBook 500 series.
(sn).
Partially supported systems
These systems lack support for the adb subsystem, but can be used with a
serial console:
Some systems are reportedly almost supported:
- LC/Performa 475/575, Quadra 605 (if 68LC040 replaced with a 68040)
- LC/Performa630 (if 68LC040 replaced with a 68040, and booted from an external SCSI drive)
- PowerBook 550c (but the internal SCSI drive is not supported yet)
Unsupported machines
- PowerPC-based Macs. Some of these are supported in the
OpenBSD/macppc port.
- Machines based on Apple's IOP technology, including the Mac IIfx.
- Machines based on the 68LC040 processor.
Unfortunately, the chip itself contains a major bug for which there is
no software workaround available in OpenBSD.
Unsupported devices
- LCPDS ethernet cards.
- Apple Communication Slot (CS) ethernet cards.
- Any other NuBus card not listed above.
