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

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.
