As of 27 Apr 2023 Big Old List of *EVERY* Custom Amiga Chip and Chipset Name I Could Find Custom Chips --------- * AAA - Advanced Amiga Architecture chipset ~ AAAGARY - 'AAA' version of the Gary. System Glue Chip, miscellaneous control circuitry * AGA - Advanced Graphics Architecture chipset + Agnus - Blitter, copper, DMA circuitry (Address Generator) ! AMOS - 'AAA' Advanced MOtherboad System controller. is a suggested single chip implementation of the Acutiator Motherboard Control system. * Fat Angus - Enhanced Angus $ Ariel - Successor to the Angus/Alice/Paula for the AA+ +* Akiko - Chunky->Planar conversion & serial (on CD32). Designed by Beth Richard + Alice - 'AA Agnus' +* Amber - Flicker Fixer gate array *~ Andrea - 'AAA' Replaces Agnus chip. Does address generation for the chip DMA channels, controls DRAM accesses, and provides the blitter and coprocessor functionality. / Beauty - Used in CDTV II. never released. $ Belle - 'AAA' Successor to the Denise/Lisa for the AA+ + Bridgette - Integrated bus buffer in the A4000 series $ Bt101KPJ/121KPJ - Digital / analog audio converters used w/some clones (Walker card (Bt101KPJ), Access, InsideOut, BoXeR and A5000 / A6000) +*% Budgie -'Memory Stuff'. Connects the trapdoor expansion port for Zorro II-like expansions and controls additional Fast RAM. +* Buster - Expansion buss controller * Fat/Super Buster - 3000 and 4000 lines use Super Buster for bus control and arbitration of both Zorro II/III subsystems + CIA - Responsible for, or take part in various I/O functions such as the serial, parallel, joystick & mouse ports + Daphne - Either a very early name for Denise, or an early version of what eventually became Denise $ Debi - Successor to the Video DAC for the AA+ + Denise/Super - Color palette, sprites, video output: Display Adapter (Daphne) + DMAC/Super - Disk IO controller * ECS - Enhanced Chipset ! EPIC - 'AAA' proposed implementation of the Acutiator Expansion Controller is the Expansion Pipeline Interface Controller. +*# Gary - System Glue Chip, miscellaneous control circuitry * Fat Gary - Upgrade for the 32-bit A3000/T and A4000/T. +* Gayle - 'Lots of control stuff' / Grace - Used in CDTV II. never released. @ Hombre - a complete system in two chips. First chip was the CPU chip and contained a RISC integer core, a blitter, a 3D colour rendering engine, audio, a CD interface, a peripheral interface, a bus interface and controllers for display and system memories. The second chip was the video data path and contained line buffers, a colour lookup table, etc. &$ Kelly - Would have been the A3000+'s/AA3000's RAMDAC (digital video memory to analog RGB converter chip) + Kickstart - Responsible for holding the core of the Amiga operating system, (loosely consider as the kernel) *~ Linda - AAA Chip - Provides a line data buffer not found in the old chip set. Buffers display data on a line by line basis to allow higher effective display bandwidth for higher resolution displays and at the same time permitting a degree of compatibility with old software. + Lisa - 'AA Denise' *~ Mary - 'AAA Paula' Replaces the old PAULA chip. Responsible for floppy disk control, audio, uart, interrupt generation, pot, and mouse control. *~ Monica - 'AAA Denise' Graphics Chip (see HCS) Replaces the old DENISE chip. This chip processes all display data including Sprite information. $ Nathalie - One of two chips that made up the Hombre chipset $ Nathaniel - One of two chips that made up the Hombre chipset * OCS - Original Chipset + Paula - Audio, floppy, joystick & interrupt circuitry: Ports and Audio (Portia) + Portia - Either a very early name for Paula, or a very early version of what eventually became Paula ! RACE - 'AAA' Ram, AMI, and CPU/Expansion controller. Is a suggested single chip implementation of the CPU/RAM control device. +* Ramsey - Ram controller with DMA % Ranger - A prototype computer that was supposed to be the second generation Amiga chipset prior to ECS. ! SAIL - 'AAA' Synchronous Amiga Interface with Latch device. Is a single Chip implementation of the Amiga Chip Controller for use with the AAA Chip bus subsystem defined by the Andrea Chip. * Super DMAC - SDMAC (A3000/T) provides DMA and bus interface for integrated WD33C93A SCSI controller. (used w/Ramsey) $ Super I/O - Component of the Walker. managed E-IDE, EPP (Enhanced Parallel Port), serial port, MIDI and high-density PC floppy drive. + Toni - Used in Walker. system bus controller, including DRAM & possibly controlling the FIDO serial ports and other I/O. $ Video DAC - Transform digital signals from the Amiga into analog signals for the monitor (triple 8 bit) * Vidiot - A hybrid integrated circuit that works as digital-to-analog converter (DAC) for the OCS/ECS ^ 6500 - CDTV keyboard controller ^ 6525 - CDTV CD-ROM controller ^ 6554 - CDTV front panel controller $ 7883/78835 - Filter and converter audio digital/analog 18 bits. They are present on the CD32 (LC78835M) and the CDTV (LC7883M). * 8727 DMA - Used w/A2090(A) ST-506/SCSI controller. provides DMA mgmt. for Konan DJC-002 (ST-506) and WD33C93 SCSI controllers * 390562 - 'Hedley Controller' 390562-01 was used in the A2024 high resolution monitor and controlled the frame buffer * = https://wikipedia.com + = https://bigbookofamigahardware.com/ / = http://www.l8r.net/technical/t-achips.shtml ^ = http://amiga.resource.cx/mod/cdtv.html & = https://retrocomputing.stackexchange.com/questions/1536/what-is-the-kelly-chip $ = http://obligement.free.fr/articles/chipsetamiga.php#kelly # = https://web.archive.org/web/20040626094812/http://www.vgr.com/tbocl/MAIN.html % = https://www.amigawiki.de/doku.php?id=en:models:ranger_chipset @ = http://www.bambi-amiga.co.uk/amigahistory/21helper.txt ! = https://haynie.amigaworld.de/research/acutiatr/docs/acu1.pdf (**Note PDF***) ~ = https://archive.org/details/advanced-amiga-architecture Chipsets --------- - OCS - Original Chip Set - used in the earliest Commodore Amiga computers and defined the Amiga's graphics and sound capabilities. - RCS - Ranger Chipset - unreleased prototype. intended to be the second-generation Amiga chipset, prior to ECS - ECS - Enhanced Chipset - minor improvements over the original chipset (OCS) - AGA - Advanced Graphics Architecture - third-generation Amiga graphic chipset. A1200/4000 - AAA - Amiga Advanced Architecture - intended for the next-generation Amiga multimedia systems. replaced by Hombre (prototype: Nyx) - AA+ - Advanced Architecture+ - Last classic compatible chipset. They planned to release it in 1994 for low end Amiga computers along with AAA. - AA+ Access - Advanced Architecture+ Access - adopted by Mick Tinker (Access) next gen AGA but was never completed - HCS - Hombre Chipset - intended as the basis of its next generation game machine called CD64 and a 3D accelerator PCI card.
