  Consider:  When was the last HP-16C calculator sold?
Why did HP quit
 selling it, but still sells the HP-12C financial calculator to this
 day?  It would seem that if there were really a market, the 12C
 chassis could be reprogrammed to continue the 16C line.  But it's not-
 -because few need to sit over a dump and work out what went wrong.
 Because nobody works at that level any longer; it would not be a
 profitable product for HP. 
Another reason might be that HP is just too expensive ?
Just 3 years ago I bought a scientific calculater which also does hex,octal, binary and
has all the logic functions. Price : 5 USD new.....
Admittedly no RPN, keyboard less good, but still fully usable.
