This Yamaha computer is specialised in music and sound production. In fact it is a low range MSX 1 computer, with a built-in SKW-01 Yamaha synthesizer which turns the computer into a real synthesizer with a sound quality really suprising for that time, and the ability to change or create you own sounds.
The CX5 is in fact the same computer as the Yamaha YIS-303, but with the SKW-01 Sound Module built-in.
Yamaha also produced upgraded versions of this computer : the CX5M and the YIS-503.
