The Gradiente Expert Plus and DD-Plus are a Brazilian MSX 1 computer composed of two parts: the main unit and the keyboard. As many Brazilian products, no technical manual was officially released describing the board switches and jumpers, which B@SS MSX covers in this article.
In Brazil, a company called Gradient released a few cloned versions of the MSX. The first version was a gray version called Expert, and it had two releases: 1.0 and 1.1. However, when it was the time to release the MSX 2.0, for some reason Gradient stepped back with its plans and released the MSX Plus and DD-Plus as MSX 1 version with only few enhancements, being the DD-Plus a release with a 3 1/2 drive embedded in the cabinet.
