ACSI2STM internal riser boards for Atari MegaST and MegaSTE

A perfect fit for your Atari Mega ST or Mega STE

The ACSI2STM is an open-source hard drive emulator that allows Atari ST computers to utilize SD cards as storage devices. Traditionally, this device connects externally via the ACSI port, which can lead to clutter and potential wear on connectors.

To address this, we've developed two new riser boards that enable the internal installation of the ACSI2STM device within Atari Mega ST and Mega STE computers. This enhancement allows users to integrate the ACSI2STM seamlessly into their systems, eliminating the need for external connections and external powering, and preserving the original aesthetics of the computer.

Benefits of Internal Installation:

• Internal Power Supply: No more wires to power your external device.
• Preserved Aesthetics: Maintains the original look of your Atari by keeping the ACSI2STM device concealed within the case.
• Reduced Wear: Minimizes wear on external ports and connectors by eliminating the need for constant plugging and unplugging.
• Space Efficiency: Frees up workspace by removing external devices and cables.

Key Features of the Riser Boards:

• Tailored Design: Specifically designed to fit the internal architecture of the Atari Mega ST and Mega STE models.
• Easy Installation: Clear instructions, making the upgrade process straightforward for users with basic technical skills.
• Secure Mounting: Ensures the ACSI2STM device is firmly seated, preventing movement and potential damage.

By utilizing these riser boards, you can enjoy the modern storage capabilities of the ACSI2STM while keeping your Atari setup clean and authentic. This solution offers a harmonious blend of vintage computing and contemporary convenience, enhancing your overall user experience.

Important: The riser boards connect to the ACSI2STM Compact model using the 20-pin connector located at the back of the device, commonly referred to as the "Satan Disk" connector. It is essential that your ACSI2STM unit includes this connector. All ACSI2STM models produced by SidecarTridge come with this connector, though it may not be pre-soldered. Compatibility with devices from other manufacturers cannot be guaranteed.
