From a computer store that closed in the 2000's. The bags of ram, along with the sheet of notes, were put into a bag in 2002 for storage. I did not open all bags to count each piece, but going by eye & weight (about 3 pounds total) there should be 65+ modules (a mixture of 72, 144, & 168 pins.) I have been processing this store's inventory for years now, and can say with authority that they ran a tight ship and generally did not keep around things they had either not tested or were not actively selling on shelves. It has 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 still in their original packaging. Thank you for stopping by. Have a great day!
