With the MSX wiki around, it's nice to have a centralized place for MSX information and documentation. MSX fan Danjovic thought so too, and after reading the wiki article about digitizers, he decided to create his own experimental graphics tablet using a resistive touch screen.

On his blog (in Portuguese) you can read how Danjovic went about creating and testing the tablet, including the schematics for the hardware. He also created a demonstration video where you can see it in action.
