.Nx*M
|
|
\*V runs on several of the older Macintosh computers.
|
|
About 4 MB of RAM might be sufficient to boot, and the system can probably
|
|
be squeezed onto a 40 MB hard disk by leaving off an unnecessary set or two.
|
|
To actually do much compiling or anything more interesting than booting, at
|
|
least 8 MB of RAM and more disk space is recommended. About 95 MB will be
|
|
necessary to install all of the
|
|
.Nx \*V
|
|
binary system distribution
|
|
sets (note that this does not count swap space!). An additional 30 MB or so
|
|
is needed for the binary X11 distribution sets. Much more disk space is
|
|
required to install the source and objects as well (at least another 300
|
|
MB).

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.

If your 68LC040 system is not listed above, it is due to a problem with

Macintosh IIfx
|
|

|

This machine has unusual custom chips for the ADB and serial interfaces

which make 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.

This is a separate effort from the \*M port. PowerMacs use hardware that
|
|
is often fairly different from that of the \*M port. If you are
|
|
interested in this, you might want to take a look at the new
|
|
.Nx Ns /macppc
|
|
port:

Real Time Clock
|
|
.Pp
|
|
Due to oddities of the Macintosh hardware interrupt priority scheme,
|
|
.Nx*M
|
|
keeps very poor time. Under a high interrupt load (e.g.
|
|
SCSI or serial port activity) , a machine can lose several minutes
|
|
per hour. A consequence of this problem is that attempting to run
|
|
.Ic xntpd
|
|
is rather pointless unless you periodically call
|
|
.Ic ntpdate .
|
|
.It
|
|
SCSI difficulties
|
|
.Pp
|
|
The
|
|
.Nx*M
|
|
SCSI drivers are not quite as
|
|
robust as their
|
|
.Tn MacOS
|
|
counterparts. Symptoms of these
|
|
problems are that some SCSI disks will not work under
|
|
NetBSD that work fine under
|
|
.Tn MacOS .
|
|
Other problems include
|
|
occasional file system corruption with some types of drives
|
|
and the general unreliability of removable SCSI media.
|
|
Keep in mind that there are no clear patterns with these
|
|
problems, and they do not appear to affect the majority of
|
|
users.
