Embedded controllers, especially in manufacturing. I work on machines that use basically an embedded Pentium 1 and a custom kernel. I know of some CNC machines running on 486 that still receive software updates but I don’t know what the OS is based on.
Absolutely. The machines I work on the most are XP embedded, but I’ve heard rumors that there are Linux based systems coming down the line.
I’m pretty sure there’s a Bridgeport conversation from back in the day that used a 486 PC running sysunix and an embedded controller card, but I could be mistaken.
