The OG40 is a 40% keyboard designed by Cosmos Design, inspired by the classic Cherry G80 series. It serves as a reinterpretation of vintage keyboard aesthetics from the 1980s to early 1990s, focusing on unique layouts that predate modern standardization. The OG40 features a BAE (Big Ass Enter) and a 10U spacebar, emphasizing usability for both experienced and new users of compact keyboards. It offers a refined 14U layout that enhances visual proportion while accommodating both 13-column and 14-column configurations for compatibility with various keycap sets. The design prioritizes functionality alongside a nostalgic aesthetic, making it a practical desktop tool rather than just a decorative item.
