I have a friend that gave me an old data logger that he use to use.....circa early 90's. Company name is Tach Time. It looks half way decent, but google doesn't show any history of the company. Manuals suggest the company home is in Duluth GA. Calling the number in the manual only suggest that I call a phone sex number 
Just wondering if if the company still exists perhaps under another name. I'm going to see if I can get it to work, but I don't want to waste too much time on it.
