I believe that at one point there was a term in a licence agreement from one of the companies involved that basically prohibited it ever being ported to anything else... but that's long ago. I wrote about the Moonshot effort recently: https://www.theregister.com/2025/04/01/risc_os_open_moonshots/ https://www.theregister.com/2025/04/01/risc_os_open_moonshot... ... And I'm still talking with ROOL about the directions they're examining. The restriction may no longer hold true.
