Revive your vintage Atari ST, STE, Mega ST, and Mega STE computers with the ultimate video conversion solution. The ST2VGA adapter seamlessly transforms your retro machine’s output into a multisync VGA signal, delivering crisp, vibrant visuals on supported monitors.

Key Features

Universal Compatibility

Designed for Atari 130ST, 260ST, 520ST/F/FM/E, 1040ST/F/FM/E, and Mega ST/E, ensuring a perfect fit across the entire Atari ST series.

Effortless Mode Switching

A simple slide switch lets you toggle between color (ST Low/Med) and mono (ST High) video modes on-the-fly.

Outstanding Video Clarity

Enjoy vivid colors and a stable, flicker-free image—provided your monitor supports a 15KHz HSYNC signal (a requirement of the original Atari video output). The adapter maintains the authentic scan frequency, preserving the classic look while enhancing display performance.

Integrated Audio Output

No need for extra cables—a built-in 3.5mm audio jack delivers a mono signal to both left and right channels, making it easy to connect your audio gear.

No Extra Power Required

The adapter operates without external power, ensuring it won’t strain your Atari’s video logic circuits. Lightweight and compact, it’s designed for reliability and longevity.

Clean, Durable Design

With a high-quality PCB and sturdy construction, the ST2VGA adapter is built to last, providing consistent performance over time.

Experience the Best of Both Worlds

Whether you’re a retro computing enthusiast, a collector, or just looking to integrate your classic Atari with modern technology, the ST2VGA adapter offers a plug-and-play solution that enhances display quality while maintaining the original charm of your machine.

Note: To use color modes, your VGA monitor must support a 15KHz HSYNC signal. This is not a scan doubler—it retains the original scan frequency, eliminating flicker while preserving the vintage feel.

Upgrade your Atari setup today with ST2VGA—a smart, reliable bridge between classic computing and modern display technology.

FAQ

How Difficult Is It to install the ST2VGA adapter?

The ST2VGA adapter is designed for easy installation, requiring no soldering or complex setup. Simply connect the adapter to your Atari ST’s video port and your VGA monitor, then toggle between color and mono modes using the slide switch.

Which Atari models are compatible with the ST2VGA adapter?

The adapter is designed to work with a wide range of Atari models, including:

• Atari 130ST
• Atari 260ST
• Atari 520ST/F/FM/E
• Atari 1040ST/F/FM/E
• Atari Mega ST/E

How do I switch between video modes?

The ST2VGA adapter offers an easy mode switching mechanism with a slide switch on top of the device to toggle between color modes (ST Low/Med) and mono mode (ST High) on-the-fly.

What video modes are available, and what are the monitor requirements?

The adapter supports both color and mono video modes:

• Color Modes (ST Low/Med): Require a monitor that supports a 15KHz HSYNC signal (multisync). If your monitor does not support 15KHz, you will not be able to use color mode.
• Mono Mode (ST High): Can be used with any compatible monitor but retains the vintage scan frequency without additional processing.

Where can I find information about compatible monitors?

For color modes, you will need a monitor that supports a 15KHz HSYNC signal. You can find a list of compatible monitors online in this website.

Note: This device is not a scan doubler; it simply provides a clean, flicker-free output by preserving the original scan frequency.

For Mono mode, any VGA monitor should work.

How is audio handled by the adapter?

The ST2VGA adapter features a built-in 3.5mm audio output jack. This jack outputs a mono signal that is wired to both the left and right channels, allowing you to connect your audio equipment directly without needing extra cables.

Does the adapter require additional power?

No, the ST2VGA adapter is designed to operate without any external power supply. It draws the necessary power directly from your Atari’s video logic circuits, ensuring a simple, hassle-free setup.

Are there any special cables needed?

A standard VGA cable is recommended. For optimal performance, consider using a cable fitted with EMI/RF noise filters (toroid/ferrite) on each end.

Can the device harm my computer?

The ST2VGA adapter is designed to be safe and reliable, ensuring it won’t damage your Atari ST, STE, Mega ST, or Mega STE computers. The adapter is engineered to draw power directly from the video logic circuits, eliminating the need for an external power source and reducing the risk of overloading or straining your Atari’s components.
