When ON+PMT is pressed on the HP 30b, then down-arrow is pressed 4 times, the display shows the "SW Version" as a date followed by a small digit in the exponent area.
The following are the SW Versions on my two 30b's, with the trailing digit being very small:
10 01 2009 ... 4
10 27 2009 ... 2
This puzzles me, since the American-format date increased, but the trailing digit decreased. Anybody know what that tiny digit refers to?
