The last of the Amiga line, the Amiga 4000 boasts new features and capabilites, surpassing all other Amiga system capabilities.

The 32-bit Motorola 68040 central processor screams along at 25MHz, making the Amiga 4000 3 to 6 times faster than the older Amiga 3000. The new powerful AGA graphics co-processor chips are capable of displaying 256 colors from a pallete of 16.7 million at 800x600 resolution. Using the special HAM-8 display mode, over 262,000 colors can be display, although with some artifacting.

For IBM PC and MS-DOS compatibility, PC video monitors are now supported in hardware and software, and the new high-density floppy drive and the included "CrossDOS" application allows the A4000 to read and write MS-DOS high density floppy disks.

Additionally, a built-in IDE hard drive controller is now standard, allowing the use of cheaper PC-style IDE hard drives instead of the more expensive SCSI hard drives of the Amiga 3000. Unfortunately, the 16-bit IDE controller is not nearly as fast as the 32-bit SCSI controller.

The Amiga's Motorola 68040 Central Processor Unit (CPU) is not part of the motherbord, but instead on a independant board of it's own, with a few additional support chips. This board then plugs into the processor slot on the Amiga motherboard, as seen here on the right.

To correct the slow hard drive access and other shortcomings of the Amiga 4000, numerous options and upgrades were developed by third party companies, independent of Commodore.

Such a fine computer system - unfortunately, Commodore couldn't compete with the IBM PC trend, was bought-out by a few other companies, but eventually filed for bankruptcy and went out of business.
