What is the status of PC/104? https://en.wikipedia.org/wiki/PC/104 I have three GPIO drivers for PC/104 machines and these are for embedded industrial usecases. I am curious about what CPUs these beasts run on in practice? Are they getting upgraded? Paging William, I think he work on these daily. Yours, Linus Walleij
