Innovations: It was the first computer to include a color graphical interface (Digital Research's GEM), and its high resolution in monochrome mode made it ideal for desktop publishing and CAD.
It also included a MIDI interface, making it a common device in music studios.
It was also the first series of personal computers to include up to one megabyte of RAM from the factory.

The ST family (which stands for Sixteen/Thirty-two, referring to the internal and external bus of the Motorola 68000 processor it included) is the successor to the Atari 8-bit family.
It rivaled the Commodore Amiga and the Apple Macintosh, for which it was a cheaper alternative.

It included the 260, 520, 1040, and Mega models, which were released between 1985 and 1991.

The PC 300GL series used Celeron, Pentium I, Pentium II, and Pentium III processors throughout its lifespan. Celeron-based models had processors clocked at 333, 366, 433, 466, 500, or 533 MHz; Pentium I models had processors clocked at 133 or 166 MHz; Pentium II-based models had processors clocked at 350, 400, and 450 MHz; and Pentium III-based models had processors with clock speeds of 450, 500, 533, 550, 600, 667, 733, 800, or 866 MHz.

These systems came in two case types: desktop and microtower.

There were two variants of the desktop case, one with two expansion slots and the other with four. Both variants had four drive bays.
The microtower case had four expansion slots and four drive bays.
