Overview

These are the device numbers of the "peripherals" connected to IOP.

DEV1

The DVD player ROM (on SCPH-18000 and later). This is often physically a part of the same IC as the boot-ROM (DEV2).

DEV2

The boot-ROM.

DEV3

USB

DEV4

SPU2

DEV5

MechaCon

DEV6

???

DEV7

???

DEV8

Originally, the parallel port of the PS1. on the PS2 it is unused on retail models, but even the DECKARD emulator still has code for handling DEV8. seems to be recycled for PowerPC UART. On DTL-T models, the DRP interface (for debugging with DECI2) is connected.

DEV9

SSBUS controller (on SCPH-3000X and later) or PCMCIA controller (on SCPH-1x000) as well as devices connected to these (SPEED).
