There was a company about 15 years back that had a new system to replace the old tape reader. I will try and remember their name. It was a pricey product. You need a tape reader and the programming board with the buttons on it and the programing manual. Just a heads up if you didn't already know. We reprogramed these many times and it was the worst thing I had ever done up until that point in my life. Don't let the reader eat the paper tape. It travels fast and the teeth on the reader will destroy the paper tape if your not carful. A new tape would be like finding the dead sea scrools
