This CPU has been stored for over two decades. Cleaned, tested, and heat sealed into an airtight, anti-static pouch. The pins are protected by an anti-static foam square. I've been putting systems like this together since the 90's and work to preserve known good parts like this one. It is one of many items from a computer store that closed in 2003 and has been carefully stored since then. It's been a unique experience reviewing this inventory- like wading through a giant time capsule! If you are interested, please check out my other listings, including many items that are still in their original packaging. Thank you for stopping by. Have a great day!
