Cleaned, tested heat-sealed into an anti-static pouch. The pins are sunk into/protected by an anti-static foam square to keep them straight during shipping. This CPU has been unused carefully stored for well over two decades. I slotted and tested this CPU personally. Having brought up many systems over the decades, I appreciate known good parts like this (anyone using their own time to build or repair a system will probably agree). This is one of many vintage items from a computer store that closed in 2003. Like a time capsule, these parts were carefully stored since then. See my other listings for more things, including many items in their original packaging! Thank you for stopping by. Have a great day!
