It only exists on consoles up to the SCPH-390XX series (GH-022 board) (as well as system 246/256). After that, it's functionality was overtaken by the new Dragon-[[MechaCon]].

On B/B'/C/C' [[Chassis types|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.
 
== Arcade SysCon ==
 
On Namco System 246 and System 256, the SysCon has some extra functionalities. The most notable extra functionality is the Arcade watchdog, which is basically a 5 minute timer to shut down the system.
 
One of the Mechacon CMDs that is involved on authentication of memory cards resets this timer if it's performed on a COH-H10020 security dongle at port 1 (mc0:).
