The seller for eBay item # 250445866736 has a complete 3420 tape drive and 3803 controller available. Located in Ladysmithc, Wisconsin. They are due to be parted out if no one speaks up for them. I inquired about these, and the seller sent me some photos. They are posted on my website at http://www.harlie.org/ibm_tape . I do not collect IBM big iron myself, but the 3420 is iconic, and folks look for them from time to time. I have no connection with the seller. --Bill
