+ * The HACK computer, including CPU, ROM and RAM.
+ * When reset is 0, the program stored in the computer's ROM executes.
+ * When reset is 1, the execution of the program restarts. 
+ * Thus, to start a program's execution, reset must be pushed "up" (1)
+ * and "down" (0). From this point onward the user is at the mercy of 
+ * the software. In particular, depending on the program's code, the 
+ * screen may show some output and the user may be able to interact 
+ * with the computer via the keyboard.
