Marrying RISC OS and Windows 11 Pro over your network The ExCOS 11 is the external variant of the ECOS 11, providing a full Windows 11 Pro computing environment in a compact, standalone enclosure. It is designed for RISC OS users who need modern Windows capability but either prefer to keep the systems physically separate or cannot fit an internal companion unit into their setup. It uses the same Intel Alder Lake-N97 processor as the ECOS 11, offering four cores running at 2.0 GHz with burst speeds up to 3.6 GHz. The standard configuration comes with 12 GB of RAM for smooth multitasking and a 256 GB SSD for storage, with upgrade options available up to 8 TB. This allows the system to be configured for anything from light productivity use to high-capacity storage for professional applications. The ExCOS 11 connects to a RISC OS system over Ethernet or Wi-Fi, enabling efficient file sharing, remote desktop access, and other forms of integration between the two environments. This setup allows RISC OS to remain active while Windows applications run in parallel, giving access to the full modern Windows software library without interrupting RISC OS workflows. Video output is provided by dual 4K HDMI ports, supporting multi-monitor configurations for Windows. This makes the ExCOS 11 suitable for office productivity, creative work, or technical applications that require extended screen space. The device is powered by an external PSU, which provides flexibility in placement, whether on a desk, in an equipment rack, or alongside other external peripherals. Like all ECOS systems, the ExCOS 11 is intended to run continuously, offering a persistent Windows environment that can be accessed at any time. This approach makes it particularly useful for mixed-platform working, where the strengths of RISC OS and Windows are both needed within a single, coordinated workspace.
