It's been a while since I updated. Sadly, I've made little progress.

My biggest problem at the moment is that I cannot expand .hqx files on my PowerBook (running System 7.1). I am absolutely stuck, because I can't find a copy of Stuffit that I can install.

I can find Stuffit as an .hqx file, but I can't open the file successfully. I've even tried opening the file using Stuffit running on Windows. The unpacking process seems to fail on Windows.

I found a program called binUnpk at this site, which supposedly can "unpack files in MacBinary format":

http://minivmac.sourceforge.net/extras/binunpk.html

I unzipped the file on my Linux machine, into a directory that I can see (via sharing) on my PowerBook. The file I want to run on the PowerBook is called "binunpk-1.0.1.dsk", and is supposedly a "zipped hfs disk image". When I double click on it on the PowerBook I get the same message I do when I click on an .hqx file:

"The program.... could not be opened because the the application program that created it could not be found."

How do you "install" a program on a Mac, anyway? Is there some trick to it?
