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

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

1.87 miod 86: OpenBSD/mac68k used to run on a large part of the 680x0-based Macintosh
1.42 miod 87: computers.
1.87 miod 88: The kernel itself had support for the following processor combinations:
1.15 johns 89: <ul>
1.42 miod 90: <li>68020 with 68851 PMMU and 68881 FPU
91: <li>68030 with 68882 FPU
92: <li>68040 (<b>not</b> including the 68LC040)
1.15 johns 93: </ul>
94:
95: <p>
1.87 miod 96: The following Macintosh models used to be supported and tested.
1.62 martin 97: This means that at least the SCSI controller, serial console and on-board
1.87 miod 98: ethernet would function on these models.
99: On some of these machines, a full 68040 CPU was required to replace the
1.62 martin 100: default 68LC040 CPU.
