Some fantastic MacOS CDs, and also some good software.
PS. Great for abandoned Operating Systems too!

All Mac files on the site are compressed with 7-ZIP. That is a problem for me.

What is your OS, why can't you just install an unarchiver?

There is a 7Zip unarchiver for DOS to Win8, if you don't have access to a windows PC, get out more 
You could run Win98 in a virtual machine, and use an old version of WinRAR off oldapps.com
maybe...
EDIT: I have not checked any of the 7zip archives, so there is a slim chance they are not usable anymore, but I am hoping (being an archival site) that all is good inside the 7zip archive. OSX has 7Zip unarchivers.

For 7z archives on a classic Mac OS you can't access them. The running win98 on a virtual machine such as VirtualPC is a good one, tmm, though for large archives this may be a problem, drive containers disk file size limitations negate DVD extraction, also the drive container disk space needs to host the 7z archive plus the extracted archive.
I've DL'd several archives from winworldpc in the past. You're usually safe with archives of CD/DVD images, but a few of the Mac floppy disk OS archives have been compressed from raw Disk Copy image files and so they have the resource forks missing (totally fubar). With floppy image .7z archives from here, its a hit & miss affair. I did get some good to go floppy archives from here tho'.

Nuked floppy images aren't entirely their fault almost everything there was pulled from Betaarchive and was once compressed as .rar (and that is just as bad...)

Ah, that does explain the presence of Betaarchive readme files I saw in some of the floppy archives which were fubar.

I was more interested in the multitude of machine-specific OS install CDs available
