| The Amiga 4000, released by Commodore in 1992, was the final major desktop model in the Amiga line before the company’s bankruptcy. It succeeded the Amiga 3000 and introduced several key hardware changes aimed at both professional and advanced home users. The A4000 came in two main variants: the Amiga 4000/040, which used a Motorola 68040 CPU, and the later, more affordable Amiga 4000/030, featuring a Motorola 68030 processor. Both models supported up to 18 MB of RAM on the motherboard (2 MB Chip RAM and up to 16 MB Fast RAM), with additional memory expansion possible via Zorro III slots. One of the most significant changes was the introduction of the Advanced Graphics Architecture (AGA) chipset. AGA improved the graphical capabilities over previous ECS systems by allowing up to 256 colors on screen from a palette of 16.8 million, as well as supporting higher resolutions and improved color handling. Unlike its predecessor, the A4000 no longer used the SCSI interface by default. Instead, it adopted the more cost-effective IDE for internal storage, a move that reduced production costs but was sometimes criticized for limiting performance. The system retained Zorro III expansion slots, ISA slots (via bridgeboard), and featured a standard high-density 3.5″ floppy drive. It typically shipped with Kickstart and Workbench 3.0 in ROM and supported modern VGA displays through its video output. Housed in a beige desktop case with a separate keyboard, the Amiga 4000 was aimed at users requiring high-performance multimedia, such as video editing or 3D rendering, and found some adoption in professional environments before Commodore’s decline. |
