StuffIt is horribly non-portable, but I can believe that it'd at least do a
better job at compression than G3 fax. Zip (in its many implementations) or
gzip would be better.

I suggested 1 bpp mainly to facilitate OCR and reprinting. For viewing
on-screen, a high-resolution, low-bit-depth image would most likely be
antialiased when it's scaled to fit.
(Ultimately, it'd be nice to have Computist in a text format of some sort,
such as HTML...it'd be even smaller. I'm not sure if the scans that are
being put up are of good-enough quality for current OCR software or if you'd
end up retyping them, but maybe an image-to-text conversion project would be
the next thing to organize once everything's scanned in.)
