Pentium 4 in pictures

Warning: graphics intensive

Someone gave our pal Digital Assassin a groovy digital camera for Christmas, and he's put it to good use taking some hi-res pix of a Pentium 4 (aka Willamette) which came into his possession.

Be warned - these pics are big. All the shots are at a desktop picture friendly 1600x1200 24-bit colour JPEGs. File sizes come in between 300KB and 700KB - download with caution!

The board itself is a WTVV - Willamette Tehama Validation Vehicle - and carries the warning 'Intel is not responsible for the misuse of this board'. Four RIMM slots, LAN, audio and video are included.

If we look at the closeup of the CPU and its Tehama chipset, you'll notice a mysterious extra power header labelled '12V CPU power'. This appears to be for the debugging circuitry on the motherboard. It will power up but not do anything if that header is not connected, and the debug led at the bottom of the motherboard sticks to "00" whereas normally it goes through a long sequence while booting. Hence, says the Assassin, the header is required to operate the computer but most likely won't be in the production model.
