I came across this proxy on Github the other day, and it's supposed to allow older machines to browse these newer sites listing even Netscape 3.0 as being able to support it (Unable to tell if Netscape is "worse" than Planetweb 3.0 or not, because I'm not fluent on its' inner workings). I'm currently abroad, and unable to test if it works, but if anybody has free time on their hands it might be worth a shot to bring online with DC

Here's a link to the Github for those curious: https://github.com/atauenis/webone/issues/34
