Comment HP's last Champion model. For a bug report see HP-17BII.
Whereas the HP-19BII is still sold frequently (as of 2003) the HP-19B is very hard to find anywhere.
Apparently, there were a number of different models:
  • An algebraic-only model.
  • An algebraic-only model with a different layout of the help text above the left keyboard, see here.
  • A combined algebraic & RPN model with "ENTER" printed below the "=" key, see here.
  • A combined algebraic & RPN model with "ENTER" printed below the "=" key and a different layout of the help text, (see above, 2nd unit).
Maybe there were two basic units (B/BII) with just two versions of the help texts: An English-only version for the US/UK market and one with language-setting instructions for the international market.
Note that the labelling is a bit confusing: All HP-19B/BII are labelled "Business Consultant II" in order to distinguish them from the HP-18C which was labelled "Business Consultant". Then there is the difference between HP-19B (algebraic only) and HP-19BII (algebraic plus RPN).
I don't know a way to have the HP-19BII display its software version number.
