Raw Normal View History

NetBSD/mac68k _VER runs on several of the older Macintosh computers.
4MB of RAM should be sufficient to boot and the system can probably
be squeezed onto a 40MB hard disk by leaving off a package or two.
To actually do much compiling or anything more interesting than
booting, at least 8MB of RAM and more disk space is recommended.
About 75MB will be necessary to install all of the NetBSD _VER binary
distribution (note that this does not count swap space!). Much more
disk space is required to install the source and objects as well (about

another 200-300MB as a guess).
Supported models:
Mac II, IIx, IIcx, SE/30, IIci, IIsi, IIvx, IIvi,
Performa 400/405/410/430, Performa 450, Performa 460/466/467,
Performa 520, Performa 550/560, Performa 600,
LC II, LC III, LC III+, LC 520, LC 550,
MacTV,
Centris 650,
Quadra 610, Quadra 630, Quadra 650, Quadra 700, Quadra 800,
Quadra/Centris 660AV, Quadra 840AV,
Supported devices on all of the above systems include:
Onboard SCSI bus and most SCSI tapes, hard drives, 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 (both Apple and a number of third party
multi-button mice are supported)
Ethernet cards based on the Natl. Semiconductor 8390 and the
SONIC (DP83932) chips

(Asante, Apple, and a few others--problems still
with ethernet and many NuBus video cards).

If your 68030 system is not listed above, it may be because of a problem
with accessing onboard video and it may still work with a serial console.

Some of the known ones in this category:
Classic-series Macs
PowerBook 100-series and Duo-series Macs
If your 68LC040 system is not listed above, it is due to a problem with
floating point emulation (FPE) for this type of processor. Machines in
this category include:
Newer LC-series machines
Newer Performa-series machines
What isn't supported, but often asked about:
Macintosh IIfx: This machine has unusual custom chips for the
ADB and serial interfaces which makes support for it
difficult. Work is in progress on this, though.
Quadra 900/950: These machines have I/O processor chips for their
ADB interfaces similar to those used in the IIfx and thus
face similar support problems.

PowerPC-based Macs. This will be separate from this port.
The PowerPC is a much different processor as is much of
the hardware inside these machines. If you are
interested in this, you might want to take a look at
http://www.mklinux.apple.com/. In addition, there is
also a NetBSD-powerpc port. For more information, please
