605 Operating Systems
makes a mac a mac? Certainly the hardware - the particular processors,
ROMs and ports that are common to macs of a particular age, but there's
also the Operating System - the software that you're constantly in contact
with. For good or bad, many macs never run anything but the standard
system software they came with - but that's not always the best option.
If you need a simple, reliable graphical interface, by all means stay
with the Mac OS - It works and works well. However if you need a server
that'll sit and work for you day after day after day a Unix-based system
may work better for you. Perhaps in the end, like me, you just want
to experience a bit of everything, have heard a bit about this linux
thing, and want to check it out. Whichever way, here are a few options...
original Quadra 605s as delivered from Apple came with System 7.1 installed,
and a set of six floppy disks for reinstalling. Further revisions to
the Mac OS would run on the 605, up to and including OS 8.1.
Just about the fastest you'll get a 605 to run is with 7.1 and System
Enabler 065 - pretty much anything will work with it. In my experience
it seems the most stable system, especially when running internet applications.
However, others find 7.5.5 to work better. If you particularly miss
some of the features of later systems, most can be added to 7.1 through
various extras such as those listed below. 7.1 is the system that Quadra
605s were sold with.
Enabler 065 - Needed for 7.1 to boot on a Quadra 605.
BeHierarchic - Apple
Menu submenus & other options
-Code fragment manager for 68ks - helps run Netscape 4.08 on Q605s
- Familiar networking
1.1.1 then OT
1.1.2 will give the base OpenTransport networking - including
Appletalk and TCP/IP control panels. Also installing the OT
PPP Package allows PPP dialup connections under OpenTransport
- Gives 7.1 the menubar clock like later versions.
Software 1.5.3 or
Display Software 2.0.2 - Gives a 605 under 7.1 access to higher
resolutions on later-model monitors

For a good balance
between speed and the ability to run the most recent apps, 7.5.x works
well. The big advantage to using System 7.5.3 is the cost & availability
- it's a free download from Apple, along with the updater to 7.5.5.
7.5.3 - Download the installer direct from Apple.
7.5.3->7.5.5 updater - A general stability and bugfix update
This works too - but I haven't used it :)
If you have the RAM and particularly need to run applications requiring
OS8+, then run 8.1, otherwise you can end up using an excessively large
percentage of your RAM, HD space and CPU time just keeping the OS going,
when a smaller/lighter choice may work just as well. If you particularly
need to access a HFS+ partition, you'll need 8.1 - however the Q605
(as with all 68k macs) is unable to boot from a HFS+ and must have a
HFS boot partition containing the OS to boot.
68k linux is by far the most popular 68k Linux, and with a little fiddling
it can make a useful OS for general server use. Some parts are less
refined than Linux on other platforms, but what is there is very stable.
These pages are hosted on a Quadra 605 running Debian Linux for 68k,
under a v2.2.19 kernel. While it should be possible to run Linux under
an FPU-less 68LC040, for varying reasons it's far far easier to replace
the CPU with a full 68040. See the NetBSD section for a link on LC040
Mac linux is available from the Debian
Mac Linux-68k site.
favourite, often touted as a more mature Unix style OS for 68ks, especially
NetBSD. Like Linux, the BSD variants should also run under a full 68040
instead of the Q605s native FPU-less 68LC040. For more information on
why, see the LC-040-and-BSD
