 ## Why?
 I was trying to understand why [64k RAM expansions](https://github.com/SukkoPera/OpenC16RamExpansion) do not work out-of-the-box on Commodore 16 machines, so I looked around and found some schematics. While they looked correct (and official), I found them hard to understand, as most of the components were packed together on a single page.

 ## Limitations
 **Nothing of what you find here was tested, so use at your own risk**.
 
 I haven't triple-checked everything, since the purpose of this was mainly to have a better comprehension of how memory is addressed, so **there may be errors** here and there. Please open a Pull Request or Issue if you find any.
 
+Again, if you are wondering why that is the case, you are welcome to join the project and help, instead of standing there and moaning.
