Overview[edit | edit source]
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-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 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[edit | edit source]
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:).
Hardware[edit | edit source]
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).
Pictured above is a SysCon with firmware 2C64 on a GH-015 board.
