+	\section{Registers}
+	The following are the general purpose registers that can be used.
+	\begin{itemize}
+		\item[] R1
+		\item[] ...
+		\item[] R8
+	\end{itemize}
+	\section{Memory Model}
+	Memory will be implicitly mapped I/O. The bottom 3201 bytes of memory will be reserved for the keyboard input and graphics.
+	A single byte is reserved for the keyboard's input. The current key will be stored in byte 0xF37E, with the most significant bit being a flag indicating that the keyboard 
+	is ready to be read from. This means that the character encoding is actually 7 bits.
+	Video memory starts at 0xF37F (62335 decimal), and every byte represents an ASCII character in monochrome.
