Great discussion. I can add...>> Message #10 Posted by tim m. on 22 Feb 2010, 7:30 p.m., in response to message #1 by Ignazio Cara (Italy)
...that my '35, #1143A31237, purchased from the original owner, is an early version 2 with bug that was refurbished by the owner. The back label states "HP-35" and one can see faint remnants of the old label. Plus, the original owner provided documentation indicating when the calculator was serviced for the "bug."
I'm judging that it is early v. 2 (without opening it) based on lack of red dot and S/N label style. It is conceivable that the faceplate was replaced, but the original owner had the machine serviced within a year or so of purchase, so I doubt this.
