Yamaha
YIS-303

This Yamaha computer is specialised in music and sound production. In fact it is a low range MSX 1 computer, but if you bought the special Yamaha synthesizer and piano keyboard, then you had a real synthesizer with a sound quality really suprising for that time, and the ability to change or create you own sounds.

The YIS-303 is in fact the same computer as the Yamaha CX5, but it has not got the SKW-01 Sound Module built-in.

Yamaha also produced upgraded versions of this computer : the CX5M and the YIS-503.
