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.
+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.

Supported Hardware:
-OpenBSD/mac68k now runs on most 680x0 Macintoshes. Specifically, it
-should work on:
+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 (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.
