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.
On B/B'/C/C' chassis consoles, it's located on a daughter board (GD-011 for B-chassis, GD-012 for B'-chassis, GD-013 for C and C' chassis), together with RTC, EEPROM, clock battery and part of the voltage regulation circuitry.
Hardware
Syscon is always a Toshiba TMP87C807U.
It has a Mask-ROM of 8 Kilobytes (8 K x 8 bits) and a RAM of 256 Bytes (256 x 8 bits).
