Overview
Syscon handles power, power-LEDs, tray loading (in conjunction with MechaCon, which actually controls the tray and the blue LED), front buttons and some thermal management.
It only exists on consoles up to the SCPH-39XXX series (GH-022 board). After that, it's functionality was overtaken by the new Dragon-MechaCon.
