Nobody has mentioned the HP48GX. Why? Is it too "modern"?
LOL! In a word - yes. The HP-48 range started in 1990 or thereabouts and went through to (was it) 2003 I guess? The HP-35 that I've just restored was the worlds first handheld calculator - let alone it being scientific or RPN. It dates back to 1972 - fully 20 years before the 48. Nothing wrong with the 48, it's just a bit "modern" for the museum yet.
Chris what did you feel or think when the HP35 actually fired up for the first time in over 25 years and was fully functional? They don't make them like that anymore comes to mind.
