I know this is nothing compared to what some of you come across but thought I would share an interesting photo of a GPU.
I have always wanted to collect GPU's in fact I was interested in them before CPU's. While I was trying to take the picture something kept reflecting off the surface. Once I viewed the photo I realized it was reflecting off my wifes graduation picture. I also think the focus is going out on my camera! The surface has a mirror finish.
Here are the two cpu's I came across along with a couple super sparc boards.

Thanks! 
I was looking up the numbering on the bottom of the Motorola chips which is RX1000PC, and came across this Motorola Datasheet
http://www.ortodoxism.ro/datasheets/motorola/MPC7455RXPXPNS.pdf
They mention that the X in a Motorola part number designates a "Pilot Production Prototype". |

Its a ATI x1950, many from the last couple of series like the X800 and x1950 look like this.I am going to try and find an example from each series and will post more pictures soon.
We are finally moving from a small apt. into a house and it has a workshop  . Once we move in I will be able to setup a soldering area and remove these chips from the boards. I got a couple old ATi 7000 eries boards to practice on first.
Speaking of soldering, are there any additional tools you guys recommend such as desoldering tape vs. desoldering pump? |

Desoldering braid/wick is quite handy for cleaning solder off stuff, like the bottom of "pinless" chips you have removed with an oven.
Desoldering pumps, the handheld types, are a pain in the ass on multi-layer pcbs ( braid doesnt really cut it on those either)
A hot plate setup in the back garden will work pretty well, or maybe an old oven. cpushack is a pro at this 
Oh, dont use a blow torch.  |

I use my toaster oven  Does a good job, when one can keep an eye on the temp.
I have a project to make a hot-air rework station... It's almost started! |
