I want to thank everyone that responed to my cry for assistance. Still have the problem. Very strange though. The unit was running great for years. Then needed to move so I removed the keyboard and lifted the typing uint off the base. When I reassembled the two pieces, problem surfaced. In local loop it does it with every key I press on the keyboard. Pulled the keyboard and ran ITTY through my ST-6... same issue. Perfect typing just a line feed after every character. 

Thanks again for the comments.
