@ Uxhamby:-
There's a ton of 32-bit Pups that will still run well on that thing.
Precise 571's problem nowadays is the age of its deps, and the fact that it's near impossible getting any modern browser to run with it. A few "alternatives" that spring to mind are:-
Xenialpup 7.5 (32-bit) - my own current 32-bit favourite. (I run a mixture of 32- & 64-bit Pups, including the flagship, Fossapup64 9.5, but still like the 32-bitzers. I spend more time with them than the 64-bit Pups.)

The "UPups" ('buntu-based Puppies.) The last fully 'pure' LTS-based UPup was UPupBB, based on Bionic Beaver. Peebee, the UPup's builder, has had increasing problems getting recent 32-bit UPups to compile correctly, due to Canonical messing-around & constantly changing their minds on whether to provide multi-arch support or not. UPupBB, however, is rock-solid, and is a very good Pup to use as a daily driver.

Then there's the DPups; Puppies built around Debian offerings. The most recent, DPup "Buster" 8.0 32, is a good 'un. DPup "Stretch" 7.5 32 is not bad, either. These are built by Roger Grider, "radky" on the Puppy Forums.

Finally, there's the 'Slacko' Pups. Michael Amadio, the 'head honcho', or main Puppy 'steward' since Barry Kauler stepped down a few years back ("01micko" on the Forums), has been building the 'Slackos' for years. Slacko 7 32-bit has just been released; these are, as their name suggests, built around Slackware.

Plenty of choice, as you can see. Take a look for yourself. As for your HDD, you could do worse than do what I did; buy a cheap KingSpec SSD to replace it. A 64GB or 128 GB won't break the bank; a 64 GB would give you plenty of room for Puppy to run & play!
Hope that perhaps gives you summat to think about. Have a nose around the new Puppy Forum, if you want:-

There's plenty of life there..!
