    Cool project! This reminds me of Chis Noeding's YouTube Channel, where he's been posting his progress on running custom firmware on the newer Behringer X32 mixers - https://www.youtube.com/@pcdimmer

    This is the kind of project that makes embedded systems feel less like engineering and more like archaeology with a soldering iron.

    Using x86 in embedded products is not new, especially older ones from the 90s, it was extremely common actually to run DOS or VXworks or QNX. It's all over industrial products. In fact Intel still shipped 386 CPUs until a few years ago.* It's cool and all but if we wrote blog posts about all of them you'd be set for the next 10 years.

    * Supposedly 2007 but that does not sound right for embedded customers unless Intel built a lifetime supply.

      This is standard practice for low-volume legacy parts. A single production run will often yield enough parts for months or even years of demand; once demand gets low enough, the manufacturer will just sell what's left of the last batch, and discontinue the part when that runs out.

      A lot of SoCs in monitors have a 186-compatible core:
