Thinkin' about how depressing software archival is when you start getting into the 2000s and beyond. So much software that you basically Can't archive - not only due to legal shit, but because of online DRM that's been down for years, or digital-only distribution which means it's nigh-impossible to actually find copies to archive.
You'd think the solution would be "oh! Look to the pirates! They'll have torrents sitting around of fully cracked versions you can install offline!" But that's just the thing. All that stuff was distributed via torrents. The one major flaw of torrents is that if the file you're sharing isn't popular enough, the torrent stops existing.
You can find plenty of .torrent files for cracked versions of years-old versions of software. All of them are dead. The best you can do is add them to a 24/7 seedbox and pray to some deity that a seeder will one day come back from the dead - an unlikely event.
... So yeah, this entire post was predicated on me failing to find any software I can put on an old 32-bit Intel MacBook I have lying around. You can find older versions for PowerPC Macs because software was still distributed on discs back then. You can find software for current generation Intel and ARM Macs because they're current and used by lots of people. Got a 32-bit Mac? It's a wasteland. You know there was software for it, but you're not gonna find any of it.
