I would start by making a list of what you think are critical uses of tech, and work on trimming that list down until all that's left is almost impossible to do analog. You'll probably need to buy stamps and a good map, and learn to memorize phone numbers. Film cameras are cheap but getting processing and printing can be an expensive hassle.

I'm still wondering if search engines have replaced encyclopedias and libraries to the point that knowledge is lost or inaccessible without the Internet. I hope not, I don't believe "online is forever", too many sites and records just fade away when a book can last hundreds of years (or burn up in minutes, true).
