Menus:: ? Bugs/ROM-Versions:: brief keyboard problem history: - first generation (beginning through end of 2003, up to S/N CN352): significant amount of force to press, missed keystrokes common, keys broke easily. - second generation (up to mid-2005, not some S/N CNA515, up to S/N CNA534): less force, quieter, other problems unchanged - third generation (current, some S/N CNA515, definitely all S/N CNA534 and later): pretty good ROMs: - early 1.2x were very bad at keyboard handling - 2.00 build 50 improved handling to not miss, however, keybounce removal was very bad - various 2.01 tried some fixes - 2.05-4 build 88 brought back KEYTIME - 2.06 has things really fixed Notes:: Manufactured by Kinpo (http://www.kinpo.com.tw). This calculator uses the new Yorke chip, which is like New York, which is the Big Apple. (Insight courtesy of Marc Staps.)

HP is apparently shipping 49G+ calculators with serial numbers
in the CNA6xxxxxxx range. I picked one up today at the Fry's
near DFW airport in Dallas. The differences between this and
my previous CNA525xxxxx version are as follows:

1. The calulator now ships in cardboard box packaging instead
of the finger-slicing blister packaging.

2. The keyboard appears to be the vastly improved variety that
Eric Rechlin has described in the latest 49G+ revisions: very
48G-like, with much more quiet action and perfect accuracy,
insofar as my limited testing has shown.

3. The keys themselves *appear* to be injection-molded,
although this may just be an illusion. When I compare them to my
previous 49G+, they don't have the obvious painted-on look
that the older keys have.

4. The screen seems to be very, very slightly different in its
background color and contrast, but not really any better or
worse than the old screen.
