 * Nintendo 64**



Purpose
//What is the fundamental purpose of the device?//
 * The purpose of the Nintendo 64 is to be able to play different games with friends and family, pass some time, and to experience a new way of gaming.**

Energy
//What energy transformations are seen in its operation?//
 * The energy transformation observed in the Nintendo 64 is one from mechanical to electrical energy. The joystick converts the user's finger movements, and pressing the 11 buttons (mechanical energy) into electric pulses/signals (electrical energy) which reflects the user's choice of action onto the TV screen that the N64 is plugged into. There are three wires that plug into the TV, one is yellow, one is white, and the other is red. That is the order that they get plugged into the TV. There is also a plug that plugs into the wall. **

**Controls**
//What sensors/controls are designed into the device?//
 * A Nintendo 64 controller has 11 buttons, and a joystick in the center. There are four yellow buttons on the left side of the controller, a blue button with an 'A' on it, and a green button with a 'B' on it. There is also a red button above the joystick that says 'start' on it. There is a dark gray button on the right side shaped like a plus sign (+). On the left side of the controller, there's a dark gray button with an 'L' on it, and the same thing is on the right side, only there's an 'R' on that button. And lastly, there's a button on the bottom of the controller with a 'Z' on it. There is a metal disk underneath the buttons, which helps in conducting electricity between two strips of conductive material. This can cause the action or direction change to be shown on the screen when a certain button is pressed. **

Materials
//What material(s) are essential to the device?//
 * One of the materials which is very important to work a Nintendo 64 is the memory, also known as the RAM(Random Access Memory). The RAM helps in storing data after a game is played, such as saving the time completed on a race. A memory chip is an integrated circuit (IC) made of millions of transistors and capacitors. Normally you figure 8 bits to one byte. For many years, a 9th bit has been added as parity bit in the RAM blocks to verify correct transmission. That's why you have to transmit 9 bits, to store 8 bits in the old 30 pin RAM chips. And it takes 36 bits to store 32 bits in the 72 pin chips, which increase the cost of the RAM chip by about 12% **

//**What is scientific principle is central to its operation?**//
** When the Nintendo 64 user places the cartridge in it's proper slot, there are particular metal parts that when touched by the Nintendo 64 game cartridge's metal parts, are recognized by the game, and the sequence is loaded into the RAM. As each specific part of the game is requested, it is loaded into the RAM, and the CPU(Central Processing Unit) does its job of coordinating everything by receiving the input through the controller and directing the audio and graphic processing. **

Design
//What does a typical device look like?//
 * It is rectangular in shape, has a reset, "on" and "off" button, and 4 slots where you can put a N64 controller.** **Also, there is a slot where a game is inserted, there is a plug in back so it can plug into a wall and a different plug that has the yellow white and red plug. Also in the front, there is a place for a memory cartridge. Usually, the Nintendo 64 is dark gray in color, but there have been special editions where it has been other colors.**

Evolution
//What changes have there been (or could there be) in this device?//
 * Even though Nintendo does not make the Nintendo 64 anymore, I think that in the future, if they were to rethink that idea, and possibly make a new one (hopefully!), they could make the cartridges and the console itself better and more efficient so that it doesn't freeze up the screen from time to time. The Nintendo 64 is a very fun game console to have, and though there haven't actually been any specific changes to the game console itself, the one change that the makers of the Nintendo 64 have done is to the graphics of the more recent video games. The graphics are now much more "crisper" than before, and each character maintains its sharpness at a close range, finally removing all the pixels that could be easily seen previously. Along with the graphics, Nintendo also tweaked its sounds to make the audio better. Compared to the newer Nintendo Wii, you can tell that Nintendo really succeeded in updating their games and the entire system.**
