I welcome questions from interested bidders and offer a 30 day return privilege. I will consolidate shipping for winners of multiple items within 3 days.
Please let me know within three days of purchase if you can't use PayPal or prefer not to use that payment method. However, I accept credit card payments only through PayPal.
Shipping to any address in the U.S.
with a zip code is FREE via USPS first class mail. I ship only to the
address PayPal gives me. I offer inexpensive USPS first class
international shipping everywhere else, if you don't mind the delay and
lack of meaningful tracking.
Also, let me know if you need a
shipping method not listed here or if you need a quote for consolidated
shipping. I can use any service from FedEx or US Postal Service and will
quote you the same postage cost I pay.
International bidders: You are responsible for
paying any additional customs duties or VAT your country may charge you.

. The processor you are purchasing is a delicate part which two different people have inspected. Each of them was able to insert this CPU into an appropriate socket, but we probably have more experience than you. Please do not be offended if we include some installation instructions.
Here's the technique we use to straighten pins. It requires sunlight, a magnifier, a utility blade and perhaps a safety pin. First, hold the CPU at about a 10 degree angle to the socket and see if you can insert the outer row of pins for only one edge. If you feel any resistance, do not push down. The resistance point helps you locate the troublesome area. Use the utility blade along the sides of the pins to push up any pin that isn't upright. (If the pin is almost flattened you can raise up the end by inserting a safety pin underneath it and lifting the back of the safety pin). Then use the side of the utility blade to make the CPU pin stand up perpendicular to the base, in a line the other pins in that row. Try to avoid any pressure near the base of the pin (which is where they break off). Repeat this process for each of the 4 edges. Then decrease the angle so the inner rows of pins go in the holes and on all 4 sides. Again, try to locate any resistance points for each side and repeat as necessary. Eventually you should be able to use the CPU. Do not spend too much time on this.
