i.LINK port (SCPH-390xx and earlier)[edit | edit source]
i.LINK port (based on FireWire 400/IEEE1394 interface) was removed in SCPH-500xx and later.
i.LINK port was mostly used for creating multiplayer network involving multiple PS2 units.
Expansion Bay (SCPH-3000x to SCPH-500xx/5500x)[edit | edit source]
Expansion Bay was last time available in SCPH-500xx/5500x, so in last "FAT" model.
Removing the Expansion Bay disallowed games like Final Fantasy XI (11), or software like Linux to run on slim units.
ATA port (SCPH-700xx and earlier)[edit | edit source]
The ATA port was removed alongside the expansion bay. Despite this, the SCPH-700xx had the necessary hardware and ATA pins required to solder an HDD connection to the motherboard, effectively rendering the port completely removed in model SCPH-750xx onward.
IOP (aka MIPS R3000A/PS1 CPU) (SCPH-700xx and earlier)[edit | edit source]
Used by PS2 as the IOP or as the CPU used to run PS1 games (is the same CPU that PS1 had).
Since SCPH-750xx units, IOP was replaced by PowerPC CPU that emulates IOP.
This resulted in some minor, or major compatibility issues for PS1/PS2 game titles.
System and DVD player update ability (SCPH-900xx with BIOS v2.20 and earlier)[edit | edit source]
In BIOS v2.30 and v2.50, Sony removed support for system update via memory card to block FMCB exploit.
The system update exploit used this ability to inject own code into console RAM, and allow to run custom code that way.
It also removed support for DVD player update via memory card.
BIOS v2.30 can be found in majority of SCPH-900xx units, while BIOS v2.50 can only found in Europe-only KDL-22PX300 Bravia units.
SPC970-based MechaCon (SCPH-390xx and earlier)[edit | edit source]
It was replaced with Dragon MechaCon found in SCPH-500xx and later.
Component/RGB video output (SCPH-900xx with BIOS v2.30 and earlier)[edit | edit source]
This feature was removed in BIOS v2.50 found in Europe-only KDL-22PX300 Bravia units.
ProtoKernel BIOS (SCPH-10000/15000)[edit | edit source]
This BIOS was replaced with the final kernel BIOS found in SCPH-18000 and later.
Static RSOD until pressing RESET button (SCPH-18000 and earlier)[edit | edit source]
Press RESET button to get rid of the static RSOD, this odd behavior was fixed in SCPH-3000x and later.
PCMCIA port (SCPH-18000 and earlier)[edit | edit source]
This feature was removed in SCPH-3000x and later.
Buggy DVD Player 1.00J (SCPH-10000 with BIOS v1.00)[edit | edit source]
This update was blocked in SCPH-10000/15000 with BIOS v1.01 and later.
