This keyboard has been in storage for quite some time. IBM clicky has date on back sticker 07JAN88 model M Pit No J2 and part number 1391401. It has been tested to power on just fine, have not tested key functionality but they all sound just the way we like; clicky. The 0 on the number pad stayed depressed sometimes but still clicks and all the others are perfect. It is missing 4 keys but have been replaced with 4 universal keys and doesn't effect functionality at all. Both stands on the backare good and functioning, no cracks or break. Overall this is in really good condition. It is being sold as-is and thank you for looking.
