With the PlayStation 2 you can run Linux on MIPS[1], though it's a highly nonstandard MIPS; you'll need to get a memory card with FreeMcBoot. Plus, even if you plan to do embedded development, the PS2 is much more documented than the PS1.

As for a "more traditional computing" experience, you can always look for an SGI.

RISC-V borrows heavily from MIPS, so the two have a pretty similar development experience.

There's also the Digital Electronics "DecStation 5000" series that were R3000 and R4000 based, which could run Ultrix or probably some of the more modern BSDs.

They're probably rarer than used SGIs, but may be cheaper if you're lucky. (Though used 200MHz SGI Octanes are pretty cheap and plentiful in the US)
