Retro Bertie returns with a fascinating new build: a Commodore 64 digitizer based on Scanntronik’s original still-image video capture hardware. The design comes from Martin W., who reverse-engineered the 1995 version of this rare digitizer and packaged it into a modern DIY kit. While it doesn’t capture motion video, this replica excels at digitizing still frames—perfect for vintage computing enthusiasts curious about late ‘80s video tech.
The Commodore 64 digitizer kit includes a beautifully designed PCB, IC sockets, a user port jack, and everything else needed to replicate the original device. Even a small cartridge case is provided, complete with a label and drilling guide. Bertie walks viewers through each part, organizing and soldering components while offering helpful build notes—such as why tight transistor pins can be tricky. With the board assembled, he carefully tests for shorts and verifies voltage lines before seating the chips and closing the case.
Once the Commodore 64 digitizer is complete, it’s time to put it to work. Rather than hooking up a vintage camcorder or VCR, Bertie connects a Canon IXUS digital camera from 2004—one with composite output—to display preloaded images on the C64. To his delight, the digitizer immediately responds, converting and displaying the image in classic 8-bit style. While early software options are functional, Bertie switches to GoDot, a modern tool that offers better image processing and flexibility. The results are surprisingly detailed, even with the C64’s limited color palette.
This video isn’t just about soldering parts—it’s about preserving a slice of computing history and showing how modern tools can revive decades-old hardware concepts. Bertie’s hands-on approach and calm explanations make it easy to follow along, even for viewers new to this kind of electronics work.
