It's ARM based for which Wiki says: "Non-x86 PC/104 CPU boards based on ARM or PowerPC are also commercially available. However, such boards are not capable of running off-the-shelf PC software. In these cases, a Board Support Package is usually provided by the manufacturer for the supported operating system(s)." WRT x86 I run the search https://pc104.org/product-search-results/?kw=x86&post_tag=&product_type=&specifications=&pc-bus-technology=&user=Filter+by+Member+Company seems like all of them are based on Vortex86DX. > One and a half years ago, not dead to me. -- With Best Regards, Andy Shevchenko
