The HP-41CV Halfnut version has no daughter-board. From "Halfnut - An Internally Improved HP-41C,CV,CX" by Richard Nelson and Jeremy Smith (CHHU V2N4): "There Are Three Halfnuts: The Halfnut models that are being shipped to dealers - as of early September [1985] in the US - are HP-41CV's and HP-41CX's. There is an HP-41C Halfnut, but this model won't be used except for service of returned HP-41C's. HP-41C Halfnuts will be used only after existing supplies of repair parts are consumed." For my part, I've been looking for a Halfnut HP-41C since 1985 and have never seen one. Aurelio, this is really a rare and valuable find. I could just about eat my face from jealousy. Ceci n'est pas une signature. |
