The Amiga's Original Chip Set, code-named Lorraine, was designed by the Amiga Corporation during the end of the first home video game boom. Development of the Lorraine project was done using a Sage IV machine nicknamed "Agony" which had 64-kbit memory modules with a capacity of 1 mbit and a 8 MHz CPU .
The Original Chip Set (OCS) is a chipset used in the earliest Commodore Amiga computers and defined the Amiga's graphics and sound capabilities. It was succeeded by the slightly improved Enhanced Chip Set (ECS) and the greatly improved Advanced Graphics Architecture (AGA).

Amiga is a family of personal computers produced by Commodore from 1985 until the company's bankruptcy in 1994, with production by others afterward. The original model is one of a number of mid-1980s computers with 16-bit or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems.
All Amiga computers use two 8520 CIAs (Complex Interface Adapter) for peripheral interfacing and the system timers, except for the CD32, where these functions are performed by the Akiko chip. The CIA chips were also used in some other Commodore devices. 'Even' CIA functions: floppy control, serial control, some parallel port status
While AAA was a reinvention and huge upgrade of the Amiga architecture, project Hombre was essentially a clean slate. It took what was learned from Amiga and went in new directions, which included an on-chip CPU with a custom 3D instruction set, 16-bit and 24-bit chunky pixel display, and up to four 16-bit playfields running simultaneously.
In fact, all the custom chips can be upgraded to the Amiga Enhanced Chip Set (ECS) versions. The plastic case is made of acrylonitrile butadiene styrene, or ABS. ABS degrades with time due to exposure to oxygen, causing a yellowing of the case. Other factors contributing to the degradation and yellowing include heat, shear, and ultraviolet light.
