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-390XX 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).
Pictured above is a SysCon with firmware 2C64 on a GH-015 board.
Firmware revisions

- 1G78 (GH-001, GH-003) (A/A+ chassis)
- 1V33 (GD-011, GD-012) (B/B' chassis)
- 1V86 (?) (Namco System 246 in all? variants, Namco System 147)
- 2A69 (GD-013, GH-008, GH-010, GH-012, GH-013, GH-014, GH-016) (AB/C/C'/D/D' chassis)
- 2C64 (GH-015, GH-017, GH-018, GH-019, GH-022) (F/G chassis)
