11 Back of Newt with cover removed showing top of the Main Board Big Cirrus chip with orange sticker on the left. StrongARM processor in the middle. Clock crystal just above the Cirrus chip. Stylus tube and power switch on the right. Note the Newt symbol in the upper right of the board! 12 Middle of the Board showing plug in ROM board 14 Bottom of the Board showing the transformer for the DC-DC converter that causes the hum when then the backlight is on. Cover for the battery compartment is at the bottom. 15 The whole thing. 16 Lower right hand corner. I took these so that I would know how to reassemble the machine. The brass screws to the right hold the battery compartment cover and the top of the stylus tube down. The round head screw is one of several that hold down the Main board down to the Touch Screen/LCD/Backlight unit. The black and red leads seem somewhat sloppily soldered. This the only place in the Newt where I wondered about quality control. I think these are the main power leads from the battery compartment but I'm not sure any more. 17 Another Cirrus chip halfway up the right side and the reset switch. More of those brass screws. 18 A close up of the Newt. To the left of the Newt is a contact block of some kind. Maybe for Apple diagnostic gear? One of the wires from the Pix accelerator attaches to a contact on this block. Not that the grey cable passes through a plastic attachment on the main board. 19 Left side. ROM card removed. The RAM chips (with -10 at the end of the number on the chip) and above them the super capacitor that replaces the button cell on previous Newtons. 20 Closeup of the Engine. 21 Closeup of the big Cirrus chip (duh!) 22 More of the Cirrus chipset. 23 I got a really blurry picture of the power switch. This is very enhanced. The tiny circuit board it is attached to just lifts out of the slot it is in. 24 Lower right hand corner. Note the stainless steel spring in the of the battery compartment. This is what you feel when you slip the battery in. Note also the missing screw. This is what I used to fasten the Accelerator board in place. This was Pix' suggestion and it works fine. The machine is so solidly engineered inside that this screw is non-essential and no structural integrity is lost by removing it. 25 I can't remember what this lever does but I took a shot of it in case I had to reassemble it. 26 Top left corner. Note the PCMCIA eject button. The silver cover covers the IR assembly. 27 Opening of the Stylus tube. Placement of the red and black wires running the length of this tube and the wires from the power switch are critical to proper fit of the back cover! I was glad I had the pictures for this. The insert labeled MP2100 slips out vertically from a slot. This would have been for the RJ11 jack for the internal modem that never was. To the right of that sad gap is a plastic mounting stud. This is where the Pix accelerator board attaches by a single screw. 28 Here's a closeup of the spring assembly inside the battery compartment. This is rather tricky to reassemble. Another case where I was glad I had the pictures. 29 When you remove the top half of the stylus tube - necessary to remove the main board you see this little mechanism where the stylus tip locks in. 30 The main board, top of stylus tube, and top of battery compartment removed. This is the back of the Touch Screen/LCD/backlight assembly. 31 Top right corner. This is the flex conductor for the Touchscreen. Note the two plastic pins just to the left of it and the screw holes just above and below it. Contact is made by pressure on pads on the underside of the main board. The board is held down at this point by these two screws and aligned by the pins. This is an example of the quality of Newt's construction. 32 Upper left hand corner. This picture just shows the well where the IR stuff is and the slot where the IR lense slides in. 33,34 These screws in the bottom of the battery compartment must be removed to remove the top cover of the Newt. 35 The inside of the front cover, top right corner. This is the tiny speaker. once again routing of the wires is critical and the pictures saved the day. 36 If anyone knows what the purpose of this tab in the hinge side of the Newt is I would like to know. I can't see any. It's a tad tricky to get it in right and then keep it there while you line up the case and get it snapped together right. 37,38 The tab again and again 39 I know I took more pictures than this. My camera stores pictures on diskette. I must have misplaced a diskette. This is the last image. What you see is the back of the backlight element sitting on the the back of the LCD module. The circuitry for the LCD module is on the green circuit card which folds flat against the back of the backlight element and is connected to the motherboard by way of the white ribbon cable in the right of the picture. You see the grey translucent reflector of the LCD surrounded by its black frame which is made of a very rigid hard nylon or delrin like material. It's glossy black. If you look very closely around the edge of the black frame you will see just the edge of the frame of the touch screen which fits very snugly to the frame and is attached by bending in little tabs all around its perimeter. The backlight itself looks like a thin piece of greenish white plastic and a very thin piece of polished aluminum that have been laminated in clear plastic like the ID card from you video store or the like. I wish I had a picture of the touchscreen. It's an interesting assembly. As you can see from picture 31 it's connected to the Newt by only four conductors. One to each side of the screen. I don't remember the placement of the conductors exactly but it seems like they side ran across the bottom and up one side and the other ran across the top and down the other side. Somehow there's a unique resistance value to each point on the screen? 812 This is the soldering tip I used to install the Pix. The soldering iron has interchangable tips but only cost about 50 DM ($25 dollars at todays disgusting exchange rate). I'm afraid this was the best picture I could get. Be careful to distinguish the tip from its shadow. 999 This is picture 11 with the addition that I've drawn in a red box representing the Pix accelerator. This is approximately how big it is and I've drawn in as best I can remember where 4 of the 5 wires go. The fifth also anchors somewhere in the upper third of the main board. Also the crystal at the destination of the leftmost wire gets removed - the most delicate part of the operation. Someone on the list (NewtonTalk) said they had found pictures at Pix' website but I was not able to connect with it so this is the best I can do. Unfortuneately if I did take pictures of the installed Pix accelerator they're with the rest of the series of the disassembly somewhere but this gives some idea of how the Newt is put together. At some point I'll have to take apart my spare machine and fix it's screen and I'll have to get some better pictures but hopefully these are useful for now. Jon.
