CX5M

The Yamaha CX5M and YK10 Keyboard are like a blast from the past. The CX5M is a vintage FM synthesizer and computer music system from the 80s, essentially a musical add-on for the MSX computer standard. It’s got a built-in speaker and was known for its unique sound capabilities. The YK10 Keyboard is likely related, possibly a keyboard companion or part of the same family, designed to work with early Yamaha music tech. Both are probably super interesting for retro computing and music enthusiasts, especially those into vintage tech and DIY music projects.
