Classics & Klunkers
This is our system catalog—a curated journey through the golden age of computing. Whether you’re a dedicated collector,
a nostalgia-driven enthusiast, or simply curious to relive the magic of the early days, there’s something here for you.
Explore our growing collection, dive into articles that celebrate the history of computing, and connect with a community
of fellow retro-minded fans.
Our library currently features no fewer than 170 systems—and counting!
We focus on preserving and documenting 8- and 16-bit systems that are now considered obsolete, but we’re not afraid to bend the rules. From time to time, we spotlight newer machines we believe truly belong here—and occasionally, we include a system simply because it’s so interesting we couldn’t resist. Enjoy the journey!
Note: Retrobug compiles information from printed publications, industry experts, online resources, and our own collections. Significant effort is devoted to translating non-English sources and verifying all data for accuracy. Our goal is to maintain a comprehensive and reliable archive. Any potential copyright issues are unintentional and will be promptly addressed upon notification.
