Atari upgraded the basic design in 1986 with the 1040STF, stylized as 1040ST<sup>F</sup>: essentially a 520ST with twice the RAM and with the power supply and a double-sided [[floppy drive]] with twice the capacity, and built-in instead of external. This adds to the size of the machine, but reduces cable clutter. The joystick and mouse ports, formerly on the right side of the machine, are in a recess underneath the keyboard. An "FM" variant includes an [[RF modulator]] allowing a television to be used instead of a monitor.

The trailing "F" and "FM" were often dropped in common usage.<ref name="byte198603" /> In ''[[Byte (magazine)|BYTE]]'' magazine's March 1986 cover photo of the system, the name plate reads 1040ST<sup>FM</sup> but in the headline and article it's simply "1040ST".<ref name="byte198603" /> 
 
The 1040ST is one of the earliest personal computers shipped with a base RAM configuration of 1&nbsp;MB.<ref>{{Cite web|title=Atari 1040STFM - Computer - Computing History|url=http://www.computinghistory.org.uk/det/50511/Atari-1040STFM/|access-date=2021-05-25|website=www.computinghistory.org.uk}}</ref> With a list price of {{US$|999|1986|about=yes|round=-2}} in the US, ''[[Byte (magazine)|BYTE]]'' hailed it as the first computer to break the $1000 per megabyte price barrier.<ref name="byte198603">{{cite news | url=https://archive.org/stream/byte-magazine-1986-03/1986_03_BYTE_11-03_Homebound_Computing#page/n91/mode/2up | title=The Atari 1040ST | work=BYTE | date=March 1986 | access-date=4 July 2014 |author1=Robinson, Philip |author2=Edwards, Jon R. | pages=84}}</ref><ref name="3years"/> ''[[Compute!]]'' noted that the 1040ST is the first computer with one megabyte of RAM to sell for less than $2,500.<ref name="halfhilll198604">{{cite news | url=https://archive.org/stream/1986-04-compute-magazine/Compute_Issue_071_1986_Apr#page/n31/mode/2up | title=A Turning Point For Atari? | work=Compute! | date=April 1986 | access-date=8 November 2013 | author=Halfhill, Tom R. | pages=30}}</ref>

A limited number of 1040STFs shipped with a single-sided floppy drive of 360KB storage capacity verses 720KB in the double sided version.<ref>{{Cite web|url=http://www.computinghistory.org.uk/det/11983/Atari-1040STF/|title = Atari 1040STF - Computer - Computing History}}</ref>

We can find also lot of 520 STF versions in Europe, early models are dated 1986, December and have also a single-sided floppy drive of 360KB storage capacity.
