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
DEV5
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
DEV9C, also known as SSBUS controller (on SCPH-3000X and later) or PCMCIA controller (on SCPH-1x000). Typically connects to (SPEED).
