SPEED

Overview

SPEED provides various interfaces to the PS2, including Ethernet (using an Ethernet transceiver), IDE/ATA and an UART (to which the modem connects in case of the US-only SCPH-10281 Network Adaptor). For fat models, it comes inside the network adaptor. For slim models, it comes on the motherboard for SCPH-700XX consoles, with the IDE pins still exposed on the PCB, making it possible to connect a hard drive (which is, however, not practical in most cases, as it requires a lot of wires and soldering). It is also used in all PSX models. Starting with SCPH-750XX consoles, SPEED was not used anymore, as its functions of an network controller were integrated into the newly developed PPC405-based IOP/Deckard, with the IDE interface being removed entirely.

It is connected to an external 1k Bit / 128 Bytes EEPROM (except on the PSX?).
