- SPORTY: a custom IC that provides sound output functions
- CABOOSE: a custom processor that manages system power, the real-time clock, and parameter RAM
- DAFB (Direct Attach Frame Buffer): an IC that connects directly to the system bus and controls the video RAM or frame buffer
- ORWELL: a custom IC that connects to the system bus and controls burst-mode data transfers to the main RAM
- JDB (Junction Data Bus): one of two ICs making up the I/O Adapter, connecting the data signals from the system bus and the I/O bus
- RELAYER: one of two ICs making up the I/O Adapter, controlling the bus buffers and proving bus arbitration logic
- YANCC (Yet Another NuBus Controller Chip): a custom IC that controls the NuBus interface
Third-party ICs include:
- SCSI interface ICs: two NCR 53C96
- Sonic: the DP83932 Ethernet controller IC made by National Semiconductor
- Two VIAs similar to those in earlier members of the Macintosh II family
