  • CLUT/DAC (color look-up table and digital-to-analog converter) IC developed by Apple and used in the Macintosh Display Card4•8, 8•24, and 8•24GC
  • DFAC (Digitally Filtered Audio Chip), the sound input and filter IC first used in the Macintosh LC
  • SWIM (Super Woz Integrated Machine), the IC that supports the SuperDrive high-density floppy disk drive
  • 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 providing bus arbitration logic
  • MCU (Memory Control Unit), a custom IC that connects to the system bus and controls regular and burst-mode data transfers to and from the main RAM and ROM
  • YANCC (Yet Another NuBus Controller Chip), a custom IC that controls the NuBus interface
  • DAFB (Direct Access Frame Buffer), an IC that connects directly to the system bus and controls the video RAM (frame buffer)
  • Enhanced ASC (Apple Sound Chip), a custom IC that replaces the Apple Sound Chip
  • Sporty, a custom IC that provides sound output amplification functions
  • PSX. The PSX IC functions as the bridge between the PowerPC 603e microprocessor and the PCI bus. It provides buffering and address translation from one bus to the other.
  • O’Hare. The O’Hare IC is based on the Grand Central IC present in the Power Macintosh 7500 computer. It is an I/O controller and DMA engine for Power Macintosh computers using the PCI bus architecture
  • AWACS. The audio waveform amplifier and converter (AWACS) is a custom IC that combines a waveform amplifier with a 16-bit digital sound encoder and decoder (codec).
  • CudaLite. The CudaLite IC is a custom version of the Motorola MC68HC05 microcontroller. It provides several system functions, including ADB and PS2.
  • Ariel II. The Ariel II video chip provides a color lookup table (CLUT) and digital-to-analog converter (DAC) for driving an AudioVision monitor.
  • Curio. The Curio is a multipurpose I/O chip that contains a Media Access Controller for Ethernet (MACE), a SCSI controller, and a Serial Communications Controller (SCC).
  • BART. The BART NuBus controller chip provides the data gateway between NuBus and the CPU bus. It acts as a CPU bus master, transferring one-cycle or four-cycle transactions.
  • Squidlet is a 28-pin chip that provides a set of synchronized system clocks for Power Macintosh computers.
  • CIVIC. The Cyclone Integrated Video Interfaces Controller (CIVIC), used in the AV card, is a CMOS chip in a 144-pin package.
  • Sebastian. The Sebastian chip is a video color palette and video digital-to-analog converter (DAC) in a 100-pin CMOS configuration, used in the AV card.
  • Mickey. The Mickey is a composite video encoder in a 28-pin advanced bipolar CMOS chip. It is used in the AV card.
