I understand that I'll need this if I want to view Unicode
characters, but it shouldn't be necessary if everything is 8-bit.
On my Windows system, setting a font is sufficient. Characters in
the range 128-255 are simply displayed as-is. Sure, if I specify an
encoding that differs from the font, I'll get the wrong characters,
but that's not really a big deal, since I won't be using Emacs to
work on Unicode files.
That being said, I visited the MacOS X Emacs list and used some of
their postings in conjunction with your advice to come up with this
addition to .emacs:
(set-selection-coding-system 'mac-roman)
(set-keyboard-coding-system 'mac-roman)
(create-fontset-from-fontset-spec
"-apple-courier-medium-r-normal--14-*-*-*-*-*-fontset-david,
ascii:-apple-courier-medium-r-normal--14-140-75-75-m-140-mac-roman,
latin-iso8859-1:-apple-courier-medium-r-normal--14-140-75-75-m-140-mac-roman,
mule-unicode-0100-24ff:-apple-courier-medium-r-normal--14-140-75-75-m-140-mac-roman")
(set-frame-font "fontset-david")
(standard-display-8bit 128 255)
This allows hi-page characters generated by programs (like Gnus) to
be displayed, and I can still see the characters of my test document
after a find-file. But I still see squares when I do a insert-file
into the scratch buffer or a newly-created document buffer.

I'll see what I can do here, but I really don't want to spend the
next month writing thousands of lines of lookup tables in order to do
this.

I just found out about that menu now, when you mentioned it.
WRT my version, I downloaded the sources using the instructions here:
http://members.shaw.ca/akochoi-emacs/stories/obtaining-and-building.html
and compiled my own copy. Every binary distribution I've gotten has
failed to even launch, for some strange reason. That particular
build was made on my system in January, so was probably MacOS 10.3.1
or 10.3.2.
I just downloaded and recompiled a new copy (on MacOS 10.3.7), in case
I was seeing a bug. The new version is:
GNU Emacs 21.3.50.1 (powerpc-apple-darwin7.7.0) of 2004-12-29
But it didn't change anything.

Right. And what I'm trying to do is tell it "assume mac-roman and
ignore everything else" because that's what will be generated when I
type those characters into a buffer.

I would hope, that after setting a single font for the frame, it
would realize that I want everything to be displayed according to
that one font.
This all was much simpler back in Emacs-19. Everything was simple
and obvious before they started forcing users to re-invent the wheel.
