! OpenBSD/mac68k runs on many of the Motorola 680x0-based Macintosh machines. 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). While the system is
! quite useful (it's being run as an internet server and router), there
! is still plenty of work to be done. Please jump in and become a part
! of the action!
!
History and Status:
The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it
! supports most of the same hardware as NetBSD. This does not mean
! that OpenBSD is the same as NetBSD. Far from it. The kernel makes
! up only a small part of the full system.
!
Supported Hardware:
! OpenBSD/mac68k now runs on most 680x0 Macintoshes. Specifically, it
! should work on:
!
68020 with 68851 PMMU and 68881 FPU
!
68030 with 68882 FPU (most Macs have this)
!
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 if they are not provided by default with the
! machine.
!
Mac II, Mac IIx, Mac IIcx, Mac IIci, Mac SE/30,
!
Mac IIsi, Mac IIvx, Mac IIvi, Performa 600, Centris 650,
!
Color Classic, Classic II, LC520, LC550, Performa 4xx, LCII,
!
Supported devices on all of the above systems include:
!
Internal SCSI bus and most SCSI tapes, hard drives, and CD-ROMs
!
Internal sound--enough to beep on some machines, anyway
!
Most NuBus video cards (there have been some problems with some 24-bit color cards)
!
Both internal serial ports
!
ADB keyboards and mice
!
Ethernet cards based on the Natl. Semiconductor 8390 (Asante, Apple, and a few others)
!
Some ethernet cards based on the SONIC chip including internal Ethernet on many of Apple's non-AV Quadras/Centrises and PowerBook 500 series.
! Some systems will boot and are usable from an external terminal (serial tty or SL/IP):
!
LC475, Performa 475, Quadra 605, Quadra 950
!
possibly others
!
Some systems are reportedly almost supported:
--- 12,180 ----

OpenBSD/mac68k
! OpenBSD/mac68k runs on many of the Motorola 680x0-based Apple Macintosh
! cowputers.
! 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

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.
!
! 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
!
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 on-board frame buffer and/or adb subsystem,
! but can be used with a serial console:
!
LC475
!
Performa 475
!
Quadra 605
!
Quadra 950
!
Some systems are reportedly almost supported:
***************
*** 89,144 ****
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)
!
! What isn't supported, but often asked about:
!
!
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 which is presently being worked on. However, machines such as the Centris 605 don't work right now.
!
LCPDS ethernet cards.
!
Apple Communication Slot (CS) ethernet cards.
!
Quadra/Centris AV series' onboard MACE ethernet.

! Current information and help with installing can be found in the
! INSTALL.mac68k
! document distributed with the most recent release of OpenBSD. Also, be sure
! to see the most recent mac68k errata on the OpenBSD
! errata page. It contains some information vitally important to
! correctly installing the system from the CDROMs.
! There is a list of changes in the
! machine-independent portions of the system. Check it out.
! There is a mailing list devoted to OpenBSD/mac68k at
! mac68k@openbsd.org.
! To join the OpenBSD/mac68k mailing list, send a message body of "help"
