1.87 miod 19: OpenBSD/mac68k used to run on many of the Motorola 680x0-based Apple Macintosh
1.47 henning 20: computers.
1.87 miod 21: It used to require a Motorola 68020 or better processor, with an external
22: Motorola 68851 PMMU in case of a 68020.

1.11 briggs 60: The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it

65: Active building and testing of OpenBSD/mac68k was discontinued after

69: <p>
1.87 miod 70: Eventually the lack of a proper firmware interface, requiring the use of a
71: MacOS application as the bootloader, with little or no possibility of updating
72: this application to match progress in OpenBSD (let alone rebuild it with a
73: free software toolchain) convinced the developers to give up supporting this
74: port, and remove the code from the tree.

1.87 miod 85: OpenBSD/mac68k used to run on a large part of the 680x0-based Macintosh
1.42 miod 86: computers.
1.87 miod 87: The kernel itself had support for the following processor combinations:
1.15 johns 88: <ul>
1.42 miod 89: <li>68020 with 68851 PMMU and 68881 FPU
90: <li>68030 with 68882 FPU
91: <li>68040 (<b>not</b> including the 68LC040)
1.15 johns 92: </ul>
93:
94: <p>
1.87 miod 95: The following Macintosh models used to be supported and tested.
1.62 martin 96: This means that at least the SCSI controller, serial console and on-board
1.87 miod 97: ethernet would function on these models.
98: On some of these machines, a full 68040 CPU was required to replace the
1.62 martin 99: default 68LC040 CPU.
