There are MCU RTOSs, for example, https://www.freertos.org FreeRTOS, than can be found in many IoT devices. Not Linux, Windows, or Android. The lack of interest in the classic/vintage computing segments is a bit surprising, since many of these MCUs far exceed the computing power of many legacy platforms. Silicon is cheap. --Chuck
