1.87 miod 21: OpenBSD/mac68k used to run on many of the Motorola 680x0-based Apple Macintosh
1.47 henning 22: computers.
1.87 miod 23: It used to require a Motorola 68020 or better processor, with an external
24: Motorola 68851 PMMU in case of a 68020.

1.11 briggs 35: The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it
1.42 miod 36: used to support most of the same hardware as NetBSD.
1.84 nick 37:
38: <p>
39: Active building and testing of OpenBSD/mac68k was discontinued after
40: OpenBSD 4.6 due to lack of interest with developers and builder.
1.42 miod 41:
42: <p>
1.87 miod 43: Eventually the lack of a proper firmware interface, requiring the use of a
44: MacOS application as the bootloader, with little or no possibility of updating
45: this application to match progress in OpenBSD (let alone rebuild it with a
46: free software toolchain) convinced the developers to give up supporting this
47: port, and remove the code from the tree.

1.87 miod 56: OpenBSD/mac68k used to run on a large part of the 680x0-based Macintosh
1.42 miod 57: computers.
1.87 miod 58: The kernel itself had support for the following processor combinations:

64:
1.99 deraadt 65: <p>
1.87 miod 66: The following Macintosh models used to be supported and tested.
1.62 martin 67: This means that at least the SCSI controller, serial console and on-board
1.87 miod 68: ethernet would function on these models.
69: On some of these machines, a full 68040 CPU was required to replace the
1.62 martin 70: default 68LC040 CPU.
