I'd imagine it would be similar today. A purse full of maps, important phone numbers in my head, Skype on my computer to talk with my family and friends.
In the early days, I would go to the library to use the computer and Internet.
Yeah I've taken ubuntu and themed it like Windows XP for people. The only problem that came up was when one of them wanted to use their 1990s GPS software. I showed them google maps on their phone and they were thrilled.
Probably want to encode it on a WORM tape. (Suggestion used LTO drives on eBay)
Then store it in the centre of a sealed medium ~iron~ galvanized metal box filled with silica. (Take care not to damage the tape, without trapping moisture.)
I'd imagine it would work well if you can keep the hardware to use it functional.
The only rule was I had to get them myself (unless it was a special occasion) and not to disturb the house while gaming.
Most of my PC games were from the win95 and MS-DOS era. But I do remember getting half-life 1 and eventually 2, and all the crazy mods that came out for those.
I remember playing the leisure suit larry games and not understanding any of the jokes haha.
I've had corporate clients with halogen fire suppression systems.
I've seen home offices use lto tape and a thermal resistant safe.
I've heard of people linking networks with the neighbour and using a remote drive at their house.
