Ya I didn’t find that one in the house today so it must be on my bookshelf in the shop. I have a habit of taking them back and forth. I also have the manual that Darrin Morgan passed out but you have to take his class to get that one. I bought a special calculator for that class and haven’t touched it since. I also recorded the class as he recommended. I did enjoy the h ad porting DVD’s that are available for sale on Speed Talk from the oldtime Head porters.
