RE: 56-bit representation of numbers vs. what is displayed
The microcode n the Classic series uses the ARC chip's C register for the user stack X value, in normalized form. However, the actual entry and display uses the A and B registers along with several flags to control entry and display, so during entry the display isn't necessarily in normalized form.

While the details vary, the same general principle applies to numeric entry on all HP RPN handheld and small desktop calculators up through the Series 30. Numeric entry works in a somewhat different manner in the 41C and Voyager series.
