The HP 49g+/39g+ and their descendants the 50g/39gs run the same operating systems as the older 49g/39g except most of it runs in an emulator so they could replace the old Saturn CPUs with ARM ones. And it still runs way faster than the native version on the older devices somehow.
Plus the entire operating system is written in Reverse Polish Lisp, one of the strangest languages I’ve ever seen. Very strange devices, but still leagues ahead of any calculator produced since (at least the 49/50, the 39 is very confusing)
I think the best thing to do is to not block them when they’re detected but poison them instead. Feed them tons of text generated by tiny old language models, it’s harder to detect and also messes up their training and makes the models less reliable. Of course you would want to do that on a separate server so it doesn’t slow down real users, but you probably don’t need much power since the scrapers probably don’t really care about the speed
