The Atari Falcon030 (usually shortened to Atari Falcon), released in 1992, is the final personal computer from Atari Corporation. [1] A high-end model of the Atari ST line, the machine is based on a Motorola 68030 CPU and a Motorola 56001 digital 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]

Contents

Shortly after release, Atari bundled the MultiTOS operating system in addition to TOS. 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 the Jaguar video game console. The Falcon sold in relatively small numbers, mainly to hobbyists. [4]

Hardware

The heart of the system is the 32-bit Motorola 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 tiny cache and limits the maximum system memory to ≈14 MB.

The microprocessor is optionally supported by a Motorola 56001 DSP clocked at 32 MHz and performing 16 million instructions per second. [7] Although it is oriented to sound processing (it is directly connected to the RAM and codec via an interconnection matrix), it is also capable of graphics processing (for example, calculation of fractals, deformations, 3D projections, and JPEG decompression). It can even, jointly with the 68030, play MP3 files in real 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 the RAM, as the graphics memory is shared with system memory which can degrade performance significantly when using high resolutions or video modes requiring many bit 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 in bit plane mode. This mode is available for compatibility with the previous generation, but is quite complex to manage. There is also a true 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 the IDE bus in addition to the SCSI bus for connecting hard drives and CD-ROM drives. [5] This allows for less expensive disk and CD-ROM devices, as SCSI interfaced devices remained relatively expensive. However, the IDE 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 only programmed I/O unlike a SCSI drive that can directly access the RAM (DMA).

Legacy

Atari created a number of prototypes of the Falcon040 (based on the more capable fully pipelined, integrated-FPU, Motorola 68040, and using a "microbox" case), but canceled it. The microbox case resembled the later Sony PlayStation 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 company C-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" 1U rack case, with external keyboard and space for internal SCSI 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 a Motorola 68060.

Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- 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. These systems include the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS.

The initial model, the Atari 520ST, had limited release in April–June 1985 and was widely available in July. It was the first personal computer with a bitmapped color GUI, using a version of Digital Research's GEM from February 1985. The Atari 1040ST, released in 1986 with 1 MB of RAM, was the first home computer with a cost-per-kilobyte of less than US$1.
