Tested working. One of the RAM retention clips has broken, see photos. I do recall having to hold memory in place with a piece of tape back in the day, I guess I'm not the only one who had to deal with this design flaw. This is one of many vintage items from a computer store that closed in the early 2000's. It has been carefully stored since that time- see my other listings for more items, including many in their original packaging! Thank you for stopping by. Have a great day!
