The Amiga 1000, also known as the A1000, is the first personal computer released by Commodore International in the Amiga line. It combines the 16/32-bit Motorola 68000 CPU which was powerful by 1985 standards with one of the most advanced graphics and sound systems in its class.
This was an Amiga compatible similar to the A1200, but on a motherboard which could fit into a standard 5 1/4" drive bay. It featured either a 68020 or 68030 CPU, with a redesigned AGA chipset, and ran AmigaOS 3.1. Minimig is a hardware compatible open source re-implementation of an Amiga 500 using a field-programmable gate array .
Akiko is responsible for implementing system glue logic that in previous Amiga models were found in the discrete chips Budgie, Gayle and the two CIAs. In detail, it includes control logic for the CD32's CD-ROM controller, system timers, the two game ports, the serial ('AUX') port, and the chip memory soldered onto the motherboard. [1]
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.
Commodore Amiga 2000, hardware revision 6.2. Inside of case. RAM and the custom sound and graphics chips (Agnus, Denise, Paula) are on the right half of the motherboard, obscured by the power supply/hard drive/disk drive assembly.
It was later renamed the Amiga 1000. The Amiga 1000's graphics abilities were significantly ahead of its rivals. At a relatively affordable base price of US$1,295 (equivalent to $3,669 in 2023), the Amiga could display up to 4,096 colors, produce 8-bit stereo audio, and run several applications concurrently.
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 original motherboard was based on the previous Amiga 1000 with the addition of expansion slots, and so suffered all the same limitations. This was soon replaced by the "B2000-CR" version designed by Dave Haynie and Terry Fisher (whose names are printed on the board), which was instead based on the Amiga 500's improved design.
