1985.

The performance of this computer could almost be read out of the name. 520 were almost the size of RAM (512KB). ST stand for Sixteen/Thirty two and means 16 bit system, while 32 means 32KB ROM. But that was only as long as the operating system loaded from a floppy. It passed, however, quick to built-in OS in the expanded 192 KB ROM. The name was retained, and even added with an "F" when a built-in floppy enhanced the computer. The last letter "M" was added when Atari wanted to satisfy those who wanted to use their own TV at home, instead of buying a separate monitor. A RF-modulator was needed for that. And the whole name is completed. Atari 520 STFM.
