TheAtari Falcon030 (usually shortened toAtari Falcon), released in 1992, is the finalpersonal computer fromAtari Corporation.[1] A high-end model of theAtari ST line, the machine is based on aMotorola 68030 CPU and aMotorola 56001digital signal processor, which distinguishes it from most other microcomputers of the era. It includes a new VIDEL programmable graphics system which greatly improves graphics capabilities.[2]
Shortly after release, Atari bundled theMultiTOS operating system in addition toTOS. TOS remained in ROM, and MultiTOS was supplied on floppy disk and could be installed to boot from hard disk.[3]
The Falcon was discontinued in late 1993–a year after its introduction–as Atari restructured itself to focus completely on the release and support of theJaguarvideo game console. The Falcon sold in relatively small numbers, mainly to hobbyists.[4]

The heart of the system is the32-bitMotorola 68030 clocked at 16 MHz. It runs at about 4 MIPS[5] while displaying video modes with the fewest colors. Despite its 32-bit CPU, the Falcon does not have 32-bit architecture throughout its design, as it has a 16-bit data bus and a 24-bit address bus.[6] This reduces the 68030's performance when not operating inside its small (2x256 bytes)cache and limits the maximum system memory to ≈14 MB.
The microprocessor is optionally supported by aMotorola 56001DSP clocked at 32 MHz and performing 16 millioninstructions per second.[7] Although it is oriented to sound processing (it is directly connected to theRAM andcodec via an interconnection matrix), it is also capable of graphics processing (for example, calculation offractals, deformations, 3D projections, andJPEG decompression). It can even, jointly with the68030, playMP3 files inreal time.
Another innovation (for its time) is the VIDEL video controller. The possibilities offered by the graphics processor are limited only by its frequency (25/32 MHz core, adjustable to 50 MHz with a hardware accelerator) and the slowness of theRAM, as the graphics memory is shared with system memory which can degrade performance significantly when using high resolutions or video modes requiring manybit planes. The parameters are numerous; each timing of a video line (start, end, number of pixels, etc.) is adjustable, the image may be interlaced or not, and the vertical frequency can go down to 50 Hz interlaced to display on a television. The number of colors is also adjustable when VIDEL operates inbit plane mode. This mode is available for compatibility with the previous generation, but is quite complex to manage. There is also atrue color 16-bit mode in which bits defining each pixel are grouped together to display 65,536 colors simultaneously,[2] though CPU performance is degraded while displaying this mode.
In addition, Atari adopted theIDE bus in addition to theSCSI bus for connecting hard drives andCD-ROM drives.[5] This allows for less expensive disk and CD-ROM devices, asSCSI interfaced devices remained relatively expensive. However, theIDE connector is internal and requires case modification to connect two hard disks or a single CD-ROM. The other drawback is that this early IDE port uses onlyprogrammed I/O unlike a SCSI drive that can directly access theRAM (DMA).

Atari created a number of prototypes of the Falcon040 (based on the more capable fullypipelined, integrated-FPU,Motorola 68040, and using a "microbox" case), but canceled it. The microbox case resembled the later SonyPlayStation 2, right down to the ability to run it vertically or horizontally.[8] It is even referenced in the PS2 patent applications.[9]
In 1995, the music companyC-Lab bought the rights to the Falcon hardware design and began producing their own versions. The Falcon Mk I was a direct continuation of Atari's Falcon030 with TOS 4.04. The Falcon Mk II addressed a number of shortcomings in the original design, making it more suitable to use in a recording studio (these were unofficially termed 'Cubase modifications') such as accepting Line-level audio in without the need for a pre-amp or mixer.[10] The Falcon Mk X was mounted in a 19-inch 1U rack case, with external keyboard and space for internalSCSI hard disk drives.[11]
Due to its expansion capabilities, several accelerators have been produced. Some of them overclock the CPU and/or the bus, while others upgrade the CPU to aMotorola 68060.
