1040 STf

1040 STf - 03
The Atari 520/1040 STf is the direct successor of the Atari 260 ST and
Atari 520 ST. 
In fact, it has the same technical characteristics except form built-in
floppy drive (hence the f of STf). 

The 3.5" floppy disk drive has been integrated with the power supply
into the computer.
The early first versions of the Atari 520 STf had a RAM based 
Operating System (they have a 32 KB ROM), this ROM will be quiclky 
replaced with a 192 KB ROM which contains all the operating system
(called TOS 1.2). 

An enhanced version of the Atari 520 STf was launched a few months later :
the Atari 1040 STf which has the same characteristics as the 520 STf except
its memory (1 MB instead of the 512 KB) and the floppy disk drive :
it uses 3.5" double side disks (720 KB).
Not long after the launch of the 1040 STf, the 520 STf will be
"unofficially" equipped with 720 KB floppy disk drives.
There was also a STfM model with a built-in floppy (the f) and an
RF Modulator (the M).
