This used to be a great feature for vintage computers. If the machine had internet, you could search with HTTP site instead of HTTPS.
The alternatives listed here might not require JS, but most if not all of them require SSL. Vintage computers struggle to support that. Anyway, Google is best avoided when possible so hopefully an alternative surfaces .
I use Kagi, it's great (great results, no ads, no tracking, a lot of clever filtering tools) but it's paid.
Free, I would use Brave Search but I doesn't give me as good results as Kagi.
Luckily, as of today I can still set my user agent to something like a Playstation or ancient firefox/IE to get a lightweight HTML-based page. The results are in www.google.com/url?q= format but I can use a redirector extension for that.
Better abandon google search for something else at this point. Even if alternative search engine calls bing and google, at least they take this BS out of the way
