The original Amiga 1000 is the only model to have 256 KB of Amiga Chip RAM, which can be expanded to 512 KB with the addition of a daughterboard under a cover in the center front of the machine. [10] RAM may also be upgraded via official and third-party upgrades, with a practical upper limit of about 9 MB of "fast RAM" due to the 68000's 24-bit ...
The first Amiga computer was the "Lorraine" by Amiga Corporation in 1984, developed using the Sage IV system. [1] It consisted of a stack of breadboarded circuit boards. Commodore International purchased the company and the prototype and released the first model, Amiga 1000 in 1985.
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.

Paula chip (MOS Technology 8364 R4) used in Amiga 1000 Paula chip (MOS Technology 8364 R4) die The Paula chip, designed by Glenn Keller, from MOS Technology , is the interrupt controller , but also includes logic for audio playback, floppy disk drive control, serial port input/output and mouse/joystick buttons two and three signals.
The Amiga's native display is a planar display which is simple and efficient to manipulate for routines like scrolling or 2D composition. However, chunky displays are faster and more efficient for 3D graphics manipulation. Akiko assists this conversion in hardware, instead of shifting the bits solely by CPU code which would cause more overhead ...
On the plus side, many users considered the Amiga 3000 the most well-engineered Amiga model, and the Amiga 3000's integrated flicker filter made it painless to use inexpensive PC-style VGA monitors. In the same year as the Amiga 3000, Commodore released the US$895 CDTV , aimed to move the Amiga platform to the living room and a competitor to ...
The Amiga 4000 motherboard includes a non-functional jumper that anticipated later chips and is labeled for 8 MiB of Chip RAM—regardless of its position, the system only recognizes 2 MiB due to the limitations of the Alice chip. [3] However, the software emulator UAE can emulate an Amiga system with the design limit of up to 8 MiB of Chip RAM ...
