No, I'm not a Hacker but just interested in what was in my TiVo.  Maybe this will satisfy some peoples curiosity and cure the need to open another TiVo just to see what's in there.  These pictures are from a 14 Hour and 30 Hour TiVo.

I did not reduce the resolution of these images so that they would be as clear as possible.  Please give it a little time to load the images. 

Inside picture of TiVo

This is the side top view of a 30 Hour TiVo with the cover off.   To remove the cover, remove the 3 screws with a Torx T10 driver, slide the cover straight back about 1 and then lift up.  Be careful not to peal the security seal off.

This is another top view of a 30 hour TiVo.  Processor board on the right, power supply on the lower left beside of the fan, 2 hard drives in the upper left.

This is the top view of my 14 hour TiVo.  Note that the power connector and data connector is there for the second disk drive.

This is a top view of a 30 Hour TiVo showing where the drives mount.  Looks like a standard IDE cable with some strips cut to allow the cable to reach to the second drive.

Inside picture of TiVo

This is a top view of the motherboard.  The IDE cable connector is at the lower left side, the IR connector to the front of the unit in the lower left side, the white power connector on the board, and the connector with the red/blue wires on the board going to the fan.  There is an edge connector in the upper left side of the board.  Maybe for testing(?) or future expansion.  There is a small battery at the top of the picture mounted on the board.  

Picture of TiVo internal battery.

Since the battery is the source of several people's problems, here it is.  It is a standard 2032 battery in a slide-in holder.  One problem, you cannot remove the battery from the holder unless you raise the board out of the chassis.  Note the metal rail on the right hand side of the battery.  Was that a bad design or what?

This is a close up of the IDE connector at the left and IR connector at the top on the board.

TiVo connector

Several people have questioned me about the connector on the main board.  This is a close up of it.  It almost looks like a PCI connector but I am told that it is not.  May be for a diagnostic or Ethernet board used at the factory.

Inside picture of TiVo with drive removed.

This is a picture of a 30 Hour TiVo with one of the drives removed from the chassis.  Note the drive is mounted in a metal carrier.  The drive is mounted to the carrier on rubber standoffs.  The drive carrier is mounted to the chassis by sliding the carrier over two metal pegs on the right side and then two screws (Torx T10) on the other end.

Disk drive vibration dampeners.

This is a close up of the rubber standoffs and hard drive.

Quantum hard drive

This is a close up of one of the drives from the 30 hour unit.  They are both labeled Quantum Fireball EX 3.5 Series on the outside of the drive case.  It has a label that reads: EX13AT EX13A3L1 REV 01-C A0A0D and an ink stamped marking: AEXA 0D50.  It shows on the case that the 12.7 GB drive has 24704 cylinders, 16 heads and 63 sectors but I am not sure this is what is in the drive case.  The drives are labeled A & B with colored stickers.  The jumpers are set as follows.  The A drive has one jumper on the first set of pins beside of the IDE connector.  The B drive has no jumpers.  One of the same drive is used in the 14 hour unit.

Disk drive connectors

Here is the drive jumper on the 12 Hour TiVo.  Several people have asked about it.

Thanks to A Brown,  R Fisher, R Caldwell, E Yamanaka, Joel Winarske & others for help with the chip identification.   If you know the ID of any of the other chips or any additional information or corrections, please email me at mark@9thTee.com with the information and I will add it.  

TiVo front panel

This is a picture of the front panel off of a 12 Hour TiVo unit.  It pushes down and then pulls out at the bottom to remove.  Very simple to change the front panel to any design they want.

Which, by the way, I like this design from the 14 Hour TiVo best.

Notes: 

There is not a Secondary IDE connector on the board so more than two drives probably won't work.  At least not hooked up to a normal Secondary IDE connector.

The rubber grommets that mount under the disk drive cuts down on the noise transferred to the chassis of the TiVo.

6/15/00 Update.  Well, I just purchased a new Sony TiVo and opened it up to take pictures of all of the new stuff but, everything is the same as the Philips.  Only one 30gb drive but the motherboard and supporting items are exactly the same.  The Sony functions the same as the Philips with the biggest difference being the remote control.  I fell in love with the original remote control so I am not really happy with the Sony remote, although it is really just personal preference.
