Yamaha was responsible for a lot of the MSX hardware. Not only did they create and produce the MSX-SYSTEM setchips, the V9938, V9958 and V9990 video chips for the MSX2/MSX2+/MSX turbo R and the MSX-AUDIO, MSX-MUSIC and OPL4/YMF278B (MoonSound) sound chips, they also produced MSX1 and MSX2 computers.

Yamaha sold two computer product lines, the CX models were marketed as Music Computers, and typically sold through music stores. Depending on the region the CX model either came with a SFG FM Sound Synthesizer Unit plugged into the machine, or was added to the machine at the music store. The YIS product line was instead referred to as the Home Personal Computer, and typically sold through computer stores. A YIS model typically lacked a side-module, such as a SFG, but as they are in fact identical to CX models one can easily add one. Yamaha advertised it as an option, and even offered sets, such as the "Music System" set for the YIS-503 and YIS-503II which included a SFG-01, making them equivalent to a CX model.

Some notable Music Computers are the Yamaha CX5M and the Yamaha CX5F. Yamaha also created a lot of special versions of their MSX computers for China, Russia and Arabic speaking countries.
