Self-explanatory, in that this page is for EOPs which run on air compressors. It should come as no surprise to know that these EOPs almost universally work on a “control” or “interface” screen placed somewhere on the compressor. Since not many air compressors will feature this level of technical sophistication, one cannot effectively determine what the common OSes and architectures are for these.

All that is known, is that they have a little screen, and it displays the Linux framebuffer test upon starting up.
