NetBSD/mac68k 1.2

NetBSD/mac68k 1.2 was the third formal release of NetBSD/mac68k.

Scott Reynolds was the maintainer of NetBSD/mac68k at the time of the 1.2 release

Supported Hardware

NetBSD/mac68k 1.2 runs on several of the older Macintosh computers. A minimal system requires 4M of RAM and about 65M of disk space. By leaving out a package or two, the system can be squeezed onto a 40M disk. At least 8MB of RAM and 200MB of disk space are recommended for more serious use. The following Macintosh hardware is supported:

CPUs:
- Mac II (with PMMU)
- Mac IIx
- Mac IIcx
- Mac IIci
- Mac SE/30
- Mac IIsi
- Mac IIvx
- Mac IIvi
- Performa 600/600CD
- LC 550, Performa 550
- MacTV
Internal SCSI bus and most SCSI tapes, disks, and CD-ROMs
Internal sound (enough to beep on some machines, anyway)
Most basic NuBUS video cards (there have been some problems with some 24-bit color cards)
Both internal serial ports
ADB keyboards and mice
NUBUS ethernet cards based on the National Semiconductor 8390 (Asante, Apple, and a few others; see the ethernet status page)
Machines with no FPU. Floating point emulation for '030-based machines without a 68882 is now available.

If you have a device that's not listed, it might be compatible with something else, or we might have simply forgotten it. If all else fails, maybe you could write a driver!

Some systems will boot and are usable from an external terminal (serial tty or SLIP):

LC III, LC II
Some PowerBooks (PB 145, 160, 165c, 170, 180)
Possibly others

Please note that many of these systems will work with custom kernels. Check out the machine status page for details. Major items often asked about, but not supported in 1.2 include:

Other ethernet interfaces. There is no driver written yet for interface cards built on the SONIC (83932) chip.
68040-based Macs. Work is in progress on getting a many of the Quadras running. This requires (at least) a new SCSI driver and a new ethernet driver.
Accelerator cards are not supported with cache enabled. Most 68030 accelerators run NetBSD/Mac68k with cache disabled. There may be a version of NetBSD-current that will permit the cache to be enabled soon.
PowerMac - That is not the Mac 68k platform. PowerPC is a completely different architecture. Work is proceeding on that, too, but it is not part of this port.
