Reliable info about the Prime G1 & G2 HW design?

[n3mmr]

Is there some source of reliable info on the HW design of the HP Prime calcs, g1 as well as g2?

This is what I can recall at the moment, there might be other developments I'm not aware of or that I forgot about.

Regarding the HP Prime G1:

• There is some basic BOM information on TI-Planet's wiki (https://wiki.tiplanet.org/HP_Prime/Hardware)
• There is a QEMU fork accurate enough that it can boot* the original firmware (https://github.com/opcod3/qemuPrime/tree/s3c2416)
• There's my long-abandoned bare-metal third-party firmware (https://github.com/boricj/ripem)
  

Regarding the HP Prime G2:

• Someone ported Linux to it (https://www.zephray.me/post/hp_prime_g2_linux/)
• That same person also wrote a bit about the internals (https://www.zephray.me/post/hp_prime_g2_...gineering/)
• Another person ported some version of Windows to it (https://www.imbushuo.net/blog/archives/725)
  

*my recollection is that at some point early, pre-release firmware versions predating the unlock-style wizard did boot, it might've improved since then

Edit: if it can boot on a physical calculator or if it can run the official firmware then I consider it to contain reliable info about HW design, even if it's in source code format.

Thank you, mr Boric!
