Atari introduced the 1040STFM in 1986, building on the success of the earlier 520ST. It featured a Motorola 68000 CPU at 8 MHz and came with 1 MB of RAM, making it the first personal computer to ship with this configuration as standard. The system included a double-sided 720 KB floppy drive, an internal power supply, and an “M” RF modulator for TV output. It used the TOS operating system with the GEM graphical user interface and retained full compatibility with existing ST software and peripherals.
The 1040STF variant lacked the RF modulator and was designed for monitor use only, while the 1040STFM added television output capability. Atari initially bundled the 1040STFM with a monochrome monitor at a price of around $999, and it received praise for being the first computer to offer one megabyte of RAM for under $1000.
The 1040STFM was part of the 16/32-bit home computer era and competed directly with systems like the Commodore Amiga and Apple Macintosh. It was among the first home computers to include a bit-mapped color GUI and was the first to have built-in MIDI ports, which contributed to its popularity in music production environments.
Internally, the model saw few changes during its production life, which continued into the early 1990s. While some early units came with a single-sided floppy drive, most were equipped with the more reliable double-sided version. Its robust design and broad capabilities made it a favorite among retro computing enthusiasts. |
