This series of screenshots shows Apple’s questionably named HTML5 and web standards showcase pages displayed on a Newton MessagePad 2100.
The Newton was running Eckhart Köppen’s lightweight, text-only Courier web browser, as well as Steve Weyer’s more capable Newt’s Cape browser.
It’s a hilarious reminder to consider your audience members using older (or ancient) browsers. See the whole gallery of Newton screenshots on Flickr. He also tested the flashy new Boston Globe website, which holds up very well, too.
