Collection of sites that should be accessible over slow connections and/or on retro hardware. A main restriction for the latter are pages that require HTTPS - best practice has left retro-systems far behind.
http://frogfind.com/ - "The Search Engine for Vintage Computers" - "The search functionality of FrogFind is basically a custom wrapper for DuckDuckGo search, converting the results to extremely basic HTML that old browsers can read. When clicking through to pages from search results, those pages are processed through a PHP port of Mozilla's Readability, which is what powers Firefox's reader mode. I then further strip down the results to be as basic HTML as possible."
- this can be sort-of used to e.g. read a HTTP-only version of this wiki: http://frogfind.com/read.php?a=https://wiki.emfcamp.org/wiki/Main_Page, but navigation links etc are stripped sadly
