Notes::

Case is metallic blue and labels are hard to read.

Manual is full of typos / incorrect key sequences.

From a private email:

		...
	I decided to take an HP-6S Solar apart to look for
	markings/legends that might indicate the origin of that
	calculator. (My motivation was based on some recent successes
	with identifying the origins of other calculators.) Clearly
	etched on the PCB is "KC-117F REV3". The KC-117 is the model
	number of a very similar looking Karce calculator:

		http://www.karce.com/eng/more.asp?id=138

	I also opened my non-solar 6S and looked in it. Etched on the
	PCB is "HP127 REV0". While it does say HP, it also says 127,
	which happens to be the model number for the non-solar Karce
	KC-127:

		http://www.karce.com/eng/more.asp?id=139

	I think it is reasonable to assume that the 6S Solar and
	non-solar 6S were manufactured by Karce. (My 6S calculators
	have reasonably early production codes (CN1000x) on them. It
	might be interesting to see what is etched in a later version
	of the non-solar 6S.
