The old machines, if they still work, are not useless if you know your way around the Unix shell and aren't addicted to GUI shit. Even X11 is usable, if you stick to small WM and don't run bloated crap. Programs like the ones from suckless.org can help here. Only a few years ago I was still using an IBM Thinkpad T30 with 512 MB RAM, and 1/4 of that was pre-allocated to a RAM disk via (mfs in OpenBSD). And with the rest of the 384 MB, I could run X without even needing to trim stuff down. Even Firefox worked ok for short browing sessions. But I only ever used that to login to my bank and a couple other things I absolutely needed it for. Otherwise, Links 2, Dillo, and Lynx were my browsers of choice (but I don't visit typical modern websites).
For mainstream web browsing now you're basically fucked because Web 2.0 needs huge resources, and thus botnet hardware. But you can have a separate modern craptop just for that purpose, and use the old hardware for everything else. Or just wean yourself away from that Web 2.0 shit and give middle finger to the jew.
