Please note!
This item was acquired from a computer store closeout sale. Some images on this listing may show an opened item, however what you will receive is a "new old stock" sealed item, in equivalent condition as shown in listing images. There may be some imperfections or tears in the shrink wrap of the item.

THE ITEM IS NEW OLD STOCK AND UNOPENED. It is almost 40 years old. As such, there is unfortunately no way to guarantee the item is free from defects other than what has been described about the exterior of the item. However, I am happy to accept returns if for some reason you notice any defects or is not as described on this listing.

Feel free to contact, if you have any questions, or special arrangements. I am always glad to help!

Thanks for looking!
