The PlayStation 2 Expansion Bay (known as PlayStation BB Unit in Japan) is a 3.5" drive bay introduced with the model 30000 and 50000 PlayStation 2 (replacing the PCMCIA slot used in the models 10000, 15000, and 18000, and no longer present as of the model 70000) designed for the network adaptor and internal hard disk drive (HDD). These peripherals enhance the capabilities of the PS2 to allow online play and other features that were shown at E3 2001. ==Network Adaptor== The Network Adaptor was released together with the launch of the PlayStation 2 Network Play service. Two models of the adapter were available - one with a dial-up modem and an Ethernet jack for broadband Internet connection (sold in North America), and one with only an Ethernet interface (sold in Europe and other regions). A start-up disc ("Network Access Disc") is included with the Network Adaptor and installs a file on the memory card for connection settings which are accessible by all but one Network Adaptor compatible game. ''Tony Hawk's Pro Skater 3'' was released in November 2001 and supported the Network Adaptor hardware, but not the software as it was not finalized until much later. The Network Adaptor also provides a Parallel ATA interface and a Molex disk drive power connector to allow installation of a 3.5 in IDE hard disk drive in the expansion bay. European versions of the adapter swapped these connectors for a single proprietary connector that carried both power and ATA signals, though no product released by Sony or any other company was compatible with it. Slimline PlayStation 2 models have an ethernet port built-in, but no hard disk drive interface. However, the first slimline model (SCPH-70000) retains the circuitry required to connect a hard drive, and may be modified to add an IDE connector. This can then be adapted to utilize SATA hard drives. The maximum supported rate is 100mbps, at full duplex. It is also backwards compatible with 10mbps hardware and configurations. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PlayStation 2 Expansion Bay」の詳細全文を読む スポンサード リンク
