Commonly referred to as the “fat”, these systems have the most concise set of features, compared to the Slim. DVD drive + buttons, 2 memory card and controller slots, 2 USB ports, 1 IEEE 1394 port (earlier revisions), AV out, IR port (later revisions), and an expansion bay for the Network + HDD adapter. Quality and featureset varies by the revision. Typically the most reliable, with some variance across revisions.

==== “SCPH-10000/15000/18000” (2000) ====
==== “SCPH-10000/15000” (AKA: The 'ProtoKernels') (2000) ====


The original launch model of the PS2, exclusive to Japan. These systems lack the expansion bay of later "fat" models, instead having a slot for a PCMCIA card (SCPH-10190). The card adds network functionality, and a connector for a proprietary external HDD (SCPH-20400).

==== “SCPH-30001(R)/35001” (2000-2002) ====
These two launch models are named by the community as 'ProtoKernels' due to their early kernel software Wich had a bunch of issues. Only fix for these kernel issues as of today is the usage of a kernel replacement, such as the ones provided on HDD-OSD and PSBBN.


The launch revisions of the PS2 in the United States, with the IEEE 1394, no integrated IR, etc. These lack the ability to use the DVD remote without installing software onto the memory card. Furthermore, they have pretty unreliable lasers that are prone to failing. Lots of motherboard/chassis sub-revisions exist for this revision, and for the most part, they don’t really impact the user. Their one positive is high quality motherboards, which are surrounded by metal shielding. Overheating may be an issue. Be careful with these and their varying reliability.
Unlike the later models which have the expansion bay, these models can't boot HDD software autonomously (intentionally designed by Sony this way)
 
Chassis wise: From this models Up to the out of Japan release model. The PS2 had 10 Screws on the bottom side, and the bottom casing was the first thing you had to remove to begin disassembling.
 
==== "SCPH-18000 (2000)" ====
 
The last retail PS2 to use the PCMCIA interface for the HDD.
 
On this model, Sony made the first Major hardware redesign for the console, clearly in preparation for the out of Japan release models.
 
The kernel issues of the previous models are completely fixed on this one.
 
The same issue in regards of HDD software remains, but this time the issue was caused because the built-in DEV9 driver (the one that talks to the SPEED chip inside the network adapter) is not compatible with SCPH-10190.
 
==== "SCPH-300xx (without 'R' at the end)" ====
 
The outside of Japan release models.
 
Hardware wise, they're very similar to the SCPH-18000. But now with the expansion bay interface for the HDD.
 
==== “SCPH-300xx(R)/350xx” (2001-2002) ====
 
These models got some heavy redesigning on the motherboard. With wouldn't change that much since this model up to the 39k series.
 
The major difference was the chassis redesign.
 
Chassis wise: On these models, the amount of bottom screws dropped to 8, and disassembling now required to start from the top side of the casing.


==== “SCPH-37000” (2002) ====
==== “SCPH-37000” (2002) ====


Japanese exclusive model with no US variant. Power consumption was reduced compared to previous Japanese models.
Japanese exclusive model. Power consumption was reduced compared to previous models.
 
These models featured exclusive colors, never seen again on any other ps2 model, these are:
 
- SCPH-37000L: The 'Ocean Blue' model, featuring a semi-transparent blue colored casing.
 
- SCPH-37000B: The 'Zen Black' model, featuring a semi-transparent black colored casing


==== “SCPH-39001” (2002-2003) ====
==== “SCPH-390xx” (2002-2003) ====


One of the two “ideal” fat revisions, and typically seen as the “best” by most. Has the IEEE 1394, no integrated IR, etc. These systems upped laser and system reliability, at the cost of increased fan noise. They’re also well built, and it’s possible to swap in the fan from a 50001 into this revision.
The last FAT model before the final major hardware revision of the PS2 FAT.


==== “SCPH-50001” (2003-2004) ====
These models are believed to be the "best" in regards of disc reading and reliability.
The truth is that this was a myth fueled by modchip installers at that time, because these revisions are the easiest to modchip install.


The other “good” revision of the fat PS2. These consoles don’t have the IEEE 1394 anymore, but have included an integrated IR sensor. This allows the DVD remote to simultaneously do a lot more, while taking less space (controller spot isn’t occupied by a receiver). It’s fans are also much quieter than any prior revision. DVDs will also play at a higher quality (default res is 480p, not i). However, some say they have “cheaper” build quality. One significant caveat is within the lasers, which normally are fine, but are prone to the rare “MechaCon crash” issue. Such an issue occurs when a certain drive chip “overdrives” the laser in response to a difficult-to-read or unofficial disc. This damages the drive mechanisms, and can even damage the chip itself. Because of this, it’s advised to steer away from using the drive or install a hardware mod such as the "PIC fix" to prevent such damage.
Wich is not a minor detail, because this is also the first model to be susceptible to the MechaCon Crash (this is probably not a coincidence).


The frequency in which this issue occurs was so low that many people still believe that MechaCon crash was introduced on the 50k models.
==== “SCPH-500xx” (2003-2004) ====
The last major hardware revision of the FAT model.
The main aspects are:
- Introduction of Built-in IR receiver
- Replacement of the CPU brand used for the MechaCon
- Remotion of the SYSCON chip, whose functionality was moved into the new MechaCon
- ability to update MechaCon software via patches on encrypted area of EEPROM (this feature is the one exploited by Mechapwn)
On these models, the frequency in wich the Mechacon crash happen increased considerably.
There's also a hidden feature on these models: it was found inside their "BIOS" two new drivers (''rom0:FLASH'' and ''rom0:XFROMMAN''). These were intended to operate the XFROM, a memory card flash chip installed as a DEV9 Subsystem (just like HDD and networking), the console OSDSYS (main menu) was coded to load these drivers and search for software updates inside XFROM.
However Sony never made a network adapter revision which had this new hardware implemented, resulting on the feature to be useless. Only the PSX DESR systems had the chance of seeing this feature working.


=== “PlayStation 2 Slim” (2004-2013) ===
=== “PlayStation 2 Slim” (2004-2013) ===


A much smaller version of the PS2 that was manufactured for quite some time. These systems lose the extension port and the IEEE 1394, and often times required an external power brick. Furthermore, their individual revisions are quite hit-or-miss when it comes to homebrew, game compatibility, or laser reliability.

==== “SCPH-700xx” (2004-2005) ====
 
The first slim.
 
The first batches of this model are literally a smaller version of the 50k series.
 
To maintain network compatibility, Sony manufactured these models with a built-in SPEED chip, meaning that while not officially supported, they retain the capability of internal HDD usage. But without being able to load HDD software autonomously, like with the SCPH-1x000
 
This model have at least three major revisions.


==== “SCPH-70001/70012” (2004-2005) ====
In one of them, the Graphics Synthetiser was merged with the Emotion Engine.


With the Slim, Sony removed the expansion slot and integrated networking. This results in the loss of easy HDD installation. However, this revision actually retains a full network adapter internally, which means a drive still can be installed via modding. In essence, this Slim is just a smaller 50001. However, the “shrinking” actually worsened their reliability, making them especially prone to the MechaCon crash & overheating. Note: 70001 has only Ethernet port; 70012 has both Ethernet and 56k line port.
Also these models were very susceptible to the MechaCon crash, up to the point where Sony was sued on the USA. Thanks to this Sony fixed the issue on the last revision of this model (Wich can be identified by the MechaCon software version, has to be 6.04 or higher), an extra circuitry was added to shut down the console when MechaCon crash is about to happen.


==== “SCPH-75001” (2005-2006) ====
==== “SCPH-75001” (2005-2006) ====


Starting with this version of the Slim, the ability to mod in HDD support has been completely axed. Furthermore, internal chip changes cause these systems to run into game compatibility issues (notably, the I/O processor containing a MIPS R3000A CPU core previously used for backwards compatibility among other things was replaced with a PowerPC-based I/O processor called "Deckard"). In essence, this revision has none of the benefits of either the 70000s or the 77000s and above. They only come with minor negatives, so it’s best to avoid these. Homebrew is still possible.
The first PS2 without hardware retrocompatibility.
 
Sony removed the PS1 MIPS R3000A Wich acted as the I/O CPU, replacing it with a PowerPC CPU, which was in charge of emulating the behavior of the PS1 CPU, and also took control over the network features of the SPEED chip, which was the removed from the design of the console, allowing Sony to finally and completely ditch the hard drive support.
 
The replacement of the PS1 CPU affected both ps1 and ps2 software. Compatibility fixes where introduced for some of those affected games.  


==== “SCPH-77001” (2006-2007) ====
==== “SCPH-770xx” (2006-2007) ====


Not much has changed with these, compared to the 75001, except game compatibility. Software changes starting from this revision improved compatibility with both PS1 and PS2 games, which in essence makes it a slightly better 75001. Homebrew is once again, still possible.
Not much has changed with these, compared to the 75001, except game compatibility. Software changes starting from this revision improved compatibility with a few more PS1 and PS2 games, which in essence makes it a slightly better 75001.


==== “SCPH-79001” (2007) ====
==== “SCPH-790xx” (2007) ====


Sony’s “shrinking” trend has continued, as the 79001 is the lightest and smallest (internally) of all Slims. Otherwise, they’re pretty much the same as the 77001, with potential minor aberrations in compatibility with games. Homebrew still works fine.

Finally, the “shrinking” trend has reversed with the final Slim. This is because Sony returned to an internal PSU design with these systems, while also adjusting the external cosmetics slightly. Reliability has also been enhanced a significant amount. However, the one huge issue is that most all 900xxs are very difficult for homebrew, as a change to the BIOS disabled FreeMcBoot (the easiest method). The old firmware is found, with very few exceptions, on P-chassis consoles, which comprise most Fall 2008 (datecode 8C) and earlier units.

Reliability has also been enhanced a significant amount. However, the one huge issue is that most all 900xxs are incapable of running homebrew automatically, since Sony found out of FreeMcBoot existence and removed the system memory card update mechanisms from OSDSYS, Wich was the entry point of FreeMcBoot. The old firmware is found, with very few exceptions, on P-chassis consoles, which comprise most Fall 2008 (datecode 8C) and earlier units.

There are two (or five) PS2 models, and a variety of revisions within two of them.

Models + Revisions

Models are arranged chronologically. Revisions are underneath their respective model.

“PlayStation 2 (original)” (2000-2004)

Commonly referred to as the “fat”, these systems have the most concise set of features, compared to the Slim. DVD drive + buttons, 2 memory card and controller slots, 2 USB ports, 1 IEEE 1394 port (earlier revisions), AV out, IR port (later revisions), and an expansion bay for the Network + HDD adapter. Quality and featureset varies by the revision. Typically the most reliable, with some variance across revisions.

“SCPH-10000/15000” (AKA: The 'ProtoKernels') (2000)

The original launch model of the PS2, exclusive to Japan. These systems lack the expansion bay of later "fat" models, instead having a slot for a PCMCIA card (SCPH-10190) Wich offered the same functionalities than later network adapters, but keeping the HDD external.

“SCPH-37000” (2002)

Japanese exclusive model. Power consumption was reduced compared to previous models.

These models featured exclusive colors, never seen again on any other ps2 model, these are:

- SCPH-37000L: The 'Ocean Blue' model, featuring a semi-transparent blue colored casing.

- SCPH-37000B: The 'Zen Black' model, featuring a semi-transparent black colored casing

“SCPH-390xx” (2002-2003)

The last FAT model before the final major hardware revision of the PS2 FAT.

These models are believed to be the "best" in regards of disc reading and reliability. The truth is that this was a myth fueled by modchip installers at that time, because these revisions are the easiest to modchip install.

“SCPH-75001” (2005-2006)

The first PS2 without hardware retrocompatibility.

Sony removed the PS1 MIPS R3000A Wich acted as the I/O CPU, replacing it with a PowerPC CPU, which was in charge of emulating the behavior of the PS1 CPU, and also took control over the network features of the SPEED chip, which was the removed from the design of the console, allowing Sony to finally and completely ditch the hard drive support.

The replacement of the PS1 CPU affected both ps1 and ps2 software. Compatibility fixes where introduced for some of those affected games.

“SCPH-770xx” (2006-2007)

Not much has changed with these, compared to the 75001, except game compatibility. Software changes starting from this revision improved compatibility with a few more PS1 and PS2 games, which in essence makes it a slightly better 75001.

“SCPH-790xx” (2007)

Sony’s “shrinking” trend has continued, as the 790xx is the lightest and smallest (internally) of all Slims. Otherwise, they’re pretty much the same as the 77001.
