I have turned to ARM CPU’s in raspberry pi’s Acorn is not US and the Raspberry pi foundation is not from the US either. If Arm is not your style there is also RISC-V which is a more open standard than ARM, working with the same architecture. X86 are CISC CPU’s while ARM and RISC-V are RISC CPU’s, IBM’s Power architecture is also RISC but I am unsure if they still make them.

Either way x86, and as far as I am aware CISC, was designed by intel in side the US. RISC was designed for BBC micro outside of the US. You can get ARM and RISC-V motherboards for computers, they are out there, but I have only used ARM on my phone and tablet (both Apple sadly) and my numerous amounts of Raspberry pi’s, I have a SBC with a Rock CPU but I do not remember why I stopped using it. I do not think it was magic smoke I would have gotten rid of it if it was that it is just sitting there on my desk.
