ITEM REVIEW

Background
The Atari 1040 ST Computer represented a home and personal computing system that was manufactured by Atari and subsequently released to the public in 1985, and it was part of a significant wave of mid-80s machines that were leveraging the capabilities of the Motorola 68000 chip—a processor that operated on both 16-bit and 32-bit architectures, which effectively balanced affordability with sufficient power for performing basic multimedia tasks. The “ST” acronym stood for Sixteen/Thirty-two, which served as a nod to the CPU’s 16-bit external data bus and 32-bit internal architecture; however, enthusiasts of the machine often referred to it affectionately as the “Jackintosh,” a playful jab directed at Atari CEO Jack Tramiel and the Apple Macintosh. This computer was developed during a period characterized by fierce competition with Commodore’s Amiga line, and while the 1040ST was not the first model in the ST series—that particular honor went to the 520ST—it ultimately became the flagship model by 1986, featuring 1 MB of RAM packed into a beige case that also housed the floppy drive and power supply internally, marking a notable design shift away from the earlier external components.
Atari’s timing in releasing this innovative product was strategic, as it launched the ST just two months before the Amiga 1000 made its debut on store shelves, positioning it as a budget-friendly alternative that boasted similar specifications. The ST line leaned heavily into its graphical user interface (GEM, which was developed by Digital Research), which, although less polished than the Macintosh’s operating system, supported color displays—something that Apple’s offering initially lacked. This graphical user interface, when combined with the inclusion of built-in MIDI ports, made the ST an unexpected hit among music production circles, even as its gaming library continued to grow to include ports of popular arcade titles as well as original software. The launch price of the 1040ST in 1986 was set at $999, which also represented a significant milestone, as it successfully broke the $1,000-per-megabyte barrier for RAM, a selling point that Atari emphasized in their advertisements that specifically targeted cost-conscious buyers.
Features



Under the hood, the 1040ST operated on an 8 MHz Motorola 68000 CPU, which was paired with 1 MB of RAM in its base configuration—this was double the 512 KB available in the earlier 520ST model. Storage for the machine relied on 3.5-inch floppy disks, which had the capability of holding up to 720 KB of data, while the inclusion of an internal drive (an upgrade from the previous external models) significantly reduced cable clutter and enhanced the overall user experience. The machine’s custom chips, which included GLUE, MMU, and DMA, were responsible for managing memory and facilitating peripheral communication, thereby enabling smoother multitasking capabilities than some of its competitors in the market. The graphics capabilities of the system included resolutions that could reach up to 640×400 in monochrome or 320×200 with 16 colors from a palette consisting of 512 colors; however, later models in the STE series expanded this capability to 4,096 colors, albeit with certain limitations depending on the resolution that was selected by the user.
Unique among home computers of its time, the ST was shipped with MIDI ports that were built directly into the machine, meaning that no extra hardware was required—this particular feature endeared it to musicians who were experimenting with various digital synthesizers. The revision of the 1040STE in 1989 introduced a Blitter chip that allowed for faster graphics rendering, enhanced joystick ports that were compatible with future Atari consoles, and stereo 8-bit PCM sound; however, the CPU continued to remain clocked at 8 MHz. The connectivity options available for the machine included:
- RS-232 serial and Centronics parallel ports that could be utilized for connecting printers
- An ACSI port that facilitated connections for hard drives or other peripherals
- RGB and composite video outputs for connecting to displays
- Two joystick ports, which could be expanded to four with the use of an adapter
These various features made the ST a versatile tool that appealed to both hobbyists and professionals alike, particularly in the pre-PowerPoint eras when desktop publishing software such as Calamus was able to leverage its graphical capabilities effectively.
Popularity and Legacy
The 1040ST found its niches where its price-to-performance ratio truly shone the brightest. Music studios gravitated toward its MIDI capabilities, with artists such as Fatboy Slim and Jean-Michel Jarre utilizing STs to sequence their tracks, while home users greatly appreciated the extensive gaming catalog that it offered—titles such as Dungeon Master and Carrier Command effectively showcased the hardware’s ability to handle complex graphics and sound. In Europe, the ST temporarily outsold the Amiga, thanks to aggressive pricing strategies and bundling deals, although it never quite managed to match Commodore’s robust marketing muscle in North America. Additionally, desktop publishing emerged as an unexpected strength for the ST, as the machine’s high-resolution monochrome mode paired exceptionally well with early laser printers, appealing to small businesses looking to create professional documents.
Later models, such as the 1040STE and the TT030, introduced incremental upgrades that included faster processors, expanded color palettes, and SCSI support; however, by the early 90s, the ST line began to face obsolescence as it struggled against Windows-based PCs and the multimedia advancements offered by the Amiga. Nevertheless, the ST’s legacy continues to persist in retro computing circles, where its significant role in democratizing music production and affordable computing is frequently cited and celebrated. Emulators such as Hatari ensure that its software library remains accessible to enthusiasts, while vintage hardware modifications—such as RAM expansions and solid-state storage replacements—serve to breathe new life into the surviving units that are still in existence.

Video Reviews and Commercials
The video discusses the Atari ST computer line, introduced in the mid-1980s. It was Atari’s first 16-bit computer, featuring the GEM operating system and a graphical user interface. Within a year, a model with one megabyte of memory was released for under $1,000. The speaker also shares personal reflections on coping with lockdown isolation.
Availability and Collectability
Initially sold through various electronics retailers and mail-order catalogs, the 1040ST remained in production until the early 1990s, with later models like the STE adding new features without drastically altering the core design that had originally been established. Today, surviving units can be found surfacing on eBay, at flea markets, and on retro tech forums, with prices ranging from approximately $200 for battered systems that have seen better days to over $1,000 for pristine, modified setups that are in excellent condition. The 1040STE model tends to command higher prices due to its enhanced multimedia features, while earlier 520ST models attract collectors who are specifically seeking “original” configurations. The scarcity of certain peripherals drives up costs—for example, the SH205 hard drive, which was once considered a luxury add-on, now sells for more than the computers themselves.
Enthusiast communities work diligently to keep the ST relevant, sharing repair guides, disk images, and homebrew software with one another. Modifications such as internal Gotek floppy emulators or aftermarket CPU accelerators are quite common, allowing the ST to interface successfully with modern displays and storage solutions. Original manuals and packaging contribute to the collectible value of the systems, as do rare variants like the 1040STFM, which included a TV modulator. While the 1040ST may not be as universally coveted as the Amiga or vintage Macs, it retains a loyal following, with its historical significance firmly cemented by milestones such as that sub-$1,000 price tag and its pivotal role in shaping the computer culture of the 1980s.
