Yamaha CX-5MU RGB mod?

[eastbayarb]

Is there a way to add RGB output to a Yamaha CX-5MU music computer (MSX)?

The Yamaha CX-5MU is a MSX1 computer and therefore has a graphics chip that only produces component video(YPbPr), if you want RGB from it you have to convert the component video to RGB. There is no other solution unfortunately.
