EL-5100 Manual

I have a manual that came with the calculator and an aftermarket book that shows "power users" how to wring even more out of the machine. I moved & would need to find it as it's still packed with some of my books. If you wanted a xerox copy I can get you one but I'm keeping the original because I still use the calculator. This machine was a real classic of the early digital era. It was built when manufacturers put a lot of time effort and thought into calculators. (not like today) I still use mine after all these years. It discovered a half-dozen thermal cycles and a new theory of heat. I hope it never quits. Gary
