The 1974 Altair 8800 was the first commercially successful home-computer ever released, and MiSTer just got an open-source core for it care of Fred VanEijk and Cyril Venditti. The 8800 can be programmed to play music (like Daisy, and Fool on the Hill) and a simple bit-chasing game. While cores like this have little mass appeal, they are extremely important from an educational and preservation perspective. Much like the Computer Space arcade core, it allows users to experience the early days of the digital technologies that laid the foundation of the modern world. And, it bleeps and bloops 😛
