I also love the idea of digital prepping (? Not sure if there's a real term for it). Even just jokingly preparing to have a set of tech work after some kind of apocalypse. UPS/solar driven home LAN with a server running copies of wiki, stack overflow, various other resources. Maybe a bunch of music/movies/games. Whatever would assist us if we lost the internet and power grids.
I don't actually think that's likely to happen, but I absolutely do enjoy some mild prepping just for fun and because the effort is so low I might as well be prepared (we have a bugout bag, extensive first aid kit, all the basic tools and survival gear, etc).
It's also just handy to have this stuff around and "own" it rather than always depend on others to be there for us.

Wordstar and Supercalc (and Zork I, II and III) installed and working fine, so I'm good!
