Cool that we are still discovering new things about old hardware. My only fear is that new hardware is too locked down to extends its life for either practical or hobby use. For example, modern Intel management engine could be used to have an always on webserver that consumes very little power when idle by turning off the main processor and only monitoring a network port in low power management microcontroller. But I am sure it's all DRMed and unaccessible.
