Here’s an interview with Steve, better known in the retro community as Cosam. Steve’s been reverse-engineering console motherboards such as the Core Grafx and PC Engine Duo and he’s also created a true Sega Neptune motherboard as well! This was a fun chat that talked about his work, the importance of the Nomad and potential future projects. As always, these long-form chats are available as a video and on all podcast services – Just search your favorite app for “RetroRGB Cosam”. Here’s links to Steve and his work:

If you’d like to see Cosam’s work in action, there’s no better place than a video by Tito from Macho Nacho Productions. – He goes over the Neptune build and shows it with Divizx’s awesome Neptune shell. I also did a livestreams running MDFourier audio analysis, Sega CD testing via the Mega SD and Sega Master System testing as well – Check them out here:
