On those specs? Well, you could try Librewolf and ungoogled-chromium, but I imagine they’ll be a tad sluggish.
NetSurf, Dillo, and Links2 are more suited to low-power machines, but they don’t support HTML5. Also, NetSurf’s JavaScript implementation is fairly old, and the other two don’t support JS at all. Furthermore, Links2 doesn’t support CSS (by design).







You could try Chawan. That’s quite good.
You also have the usual selection of Links2 (text mode), Lynx, and w3m; but most modern websites will not work very well (if at all).
