MSX basic
 

I felt nostalgy on good old Yamaha computer, which we used to play with my friends in my youth. So I downloaded emulator and games, but I can't find any basic (*.bas) programs in Internet. If anybody has something from his youth or know a place where there are tutorials, it would be much appreciated.

Maybe this could be of some interest for you:
