1.87 miod 24: OpenBSD/mac68k used to run on many of the Motorola 680x0-based Apple Macintosh
1.47 henning 25: computers.
1.87 miod 26: It used to require a Motorola 68020 or better processor, with an external
27: Motorola 68851 PMMU in case of a 68020.

1.11 briggs 39: The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it
1.42 miod 40: used to support most of the same hardware as NetBSD.

44: Active building and testing of OpenBSD/mac68k was discontinued after
45: OpenBSD 4.6 due to lack of interest with developers and builder.

1.87 miod 49: Eventually the lack of a proper firmware interface, requiring the use of a
50: MacOS application as the bootloader, with little or no possibility of updating
51: this application to match progress in OpenBSD (let alone rebuild it with a
52: free software toolchain) convinced the developers to give up supporting this
53: port, and remove the code from the tree.

1.87 miod 64: OpenBSD/mac68k used to run on a large part of the 680x0-based Macintosh
1.42 miod 65: computers.
1.87 miod 66: The kernel itself had support for the following processor combinations:
1.15 johns 67: <ul>
1.42 miod 68: <li>68020 with 68851 PMMU and 68881 FPU
69: <li>68030 with 68882 FPU
70: <li>68040 (<b>not</b> including the 68LC040)
1.15 johns 71: </ul>
72:
73: <p>
1.87 miod 74: The following Macintosh models used to be supported and tested.
1.62 martin 75: This means that at least the SCSI controller, serial console and on-board
1.87 miod 76: ethernet would function on these models.
77: On some of these machines, a full 68040 CPU was required to replace the
1.62 martin 78: default 68LC040 CPU.
