Playstation 2 Motherboard Models

GH-00X

GH-001

Year 2000
Models SCPH-10000
Chassis A
Japanese launch revision
Incomplete BIOS (no DVD player); DVD player can be installed onto a memory card using an update disc
Buggy DVD player (version 1.00) that allows region free (but 60 Hz only) playback using some trick as well as RGB-output during DVD-playback, which was disabled on later versions
Later production models might come with an updated BIOS that blocks installation and startup of DVD player 1.00, as well as an updated MechaCon, just like GH-003 does

GH-003

Year 2000
Models SCPH-15000, SCPH-18000 (besides GH-008)
Chassis A (in SCPH-15000), A+ (in SCPH-18000)
In SCPH-15000, DVD player still needs to be installed first (in a newer, partially fixed version, that seemingly can also be used on SCPH-10000), but BIOS disallows use of the buggy version 1.00
In SCPH-18000, DVD player is preinstalled
Updated MechaCon for speedier tray opening/closing

Chassis H
This board and every later board comes with the newer ARM-based "Dragon" MechaCon, which also takes over the functions of SysCon as well as EEPROM and RTC
This board and every later fat board uses different driver ICs (LA6508 and LB11971) for the drive mechanism; the LA6508 is known for dying/shorting out (possibly due to overheating) and sometimes additionaly killing the laser with it

Chassis L
Introduces new PPC 405 based IOP with external 4MB DDR-SDRAM, which emulates functions of the old MIPS-based IOP as well as SPEED; has some compatibility issues
As the functions of SPEED were integrated into the IOP, having an SSBUS-controller became obsolete, thus the combined SSBUS-Controller + SPU2 chip (CXD2955R) that was introduced with GH-026 got "downgraded" to the older SPU2 (+SPU2 RAM) chip (CXD2947R), that was introduced way back with GH-017

Year 2004 - 2005
Models DESR-5500, DESR-7500, DESR-5700, DESR-7700
Chassis X
Both PSX motherboards have a total of 72 MB RDRAM, unlike normal PS2s' 32 MB
Unlike XPD-001, this board has several daughter boards:
- One large daughter board (XRC-005) with analog video interfaces as well as the Ethernet transceiver
- One smaller daughter board (XCP-005) with the SPEED chip, an unknown Pioneer chip (PE7003D) and an Altera FPGA (with its ROM and a programming header)
- A similarily named Pioneer chip (PE7005A) is found in some Pioneer DVR (DVR-920H-S), where it is labelled as an I/O expander in the service manual
- DESR-7500 and DESR-7700 also have an additional third daugher board on the opposite side of the main board, which contains the iLink-interface controller
- DESR-5500 and DESR-5700 (the XPD-005 consoles that don't have iLink) instead have a small pcb (XDI-002) with few components soldered with two wires directly to the motherboard
This board also contains 2 LEDs connected to DVRP which are invisible from the outside but light up when the console is powered up. It is not known what is indicated by these LEDs.
