Thomas Christoph has officially completed his long-running project to recreate the CMD RAMLink—hardware and all. After months of work behind the scenes, he’s now ready to show off the results of his reverse engineering efforts: a fully functional RAMLink replica, complete with a sleek aluminum case.
This isn’t just a partial rework. The entire device, including the signature metal housing, has been faithfully reproduced. Christoph has already shared a photo of the first completed prototype, which he assembled himself. The case is crafted from 1.6mm thick 5052 aluminum and anodized with a clean, clear finish. A second variant in black anodized aluminum is also in the works.
Over the last half-year, Christoph methodically rebuilt the device, starting with the RAMcards—initially releasing V1 and V2 versions. Those were followed by the RAMcard XL series, which pushed RAMLink’s capacity from the original 16MB to 64MB onboard and up to 96MB with an expansion cartridge. With those working and tested, he turned his attention to the complete RAMLink unit.
The result is a fully compatible reproduction that works with original CMD RAMcards as well as both generations of RAMcard XL. Functionality has been preserved down to the details. One of the practical changes is a new battery backup connector—replacing the original with a barrel-style plug that prevents mismatched connections.
The version shown is based on a board iteration from week 14 of 2025. Since then, Christoph has continued fine-tuning. The prototype case still needs small revisions—typical for a first run—but the hardware itself is finished. He’s already been using the unit daily for months without issue.
A new label design is also underway, and a full video breakdown will follow once the final version of the case is ready. For those eager to own one, Christoph has opened a waitlist. Pricing hasn’t been set yet, but he promises it’ll come in below the usual inflated second-hand rates. Multiple configurations will be offered, echoing how CMD sold the original units.
