I don't know this drive by model number, but IIRC it's a daul 5.25" drive with an HPIB interface. I have an HP drive that fits that description, unfortunately I can't get to it quickly, so I can't verify the model number, but I do remember some things about it. Can you post a picture of the controller card somewhere? I may have a spare one laying around here (somewhere). SteveRob
