In case anybody here is interested, a few years ago I put together a similar (albeit far less comprehensive) resource on original PlayStation programming [1], exploring the GPU, geometry coprocessor and serial I/O hardware step-by-step with plain C examples. I'm planning to extend it with more examples covering audio and CD-ROM access next, but haven't yet had the chance to do so.

This is going to be user useful for me in a few weeks as I bring up PalmOS 5 on Playstation One. Thanks.

Did you port PalmOS 5 to MIPS somehow?

[dmitrygr]

I did, yes: https://x.com/dmitrygr/status/2042036163335041305

Wow, that's really neat! Looking forward to your writeup.
