Question to HP-35 owners
In 1973, I traded my HP-35 for a HP-45. So when I created RPN-35 SD, the HP-35 simulator for iPhone, I verified its correct operation against a microcode-based emulator.
There is one point I'm unsure of, though: the lighting of decimal points in a low-battery situation. HP's Operating Manual states on page 23: "All decimal points but one light in the display when 2 to 5 minutes of operation time remain." [Emphasis mine]. Accordingly, the picture below the text shows no decimal point in the first digit of the fractional part. However, on page 28, they say: "All decimal points light to warn you that you have a few minutes of operating time left." So, the question is: how does a v3 or v4 HP-35 really behave? And if page 23 is correct, which decimal point does remain unlit? |
