2 HP 16C Calculators Up for Discussion

Yes, to my knowledge there were at least two processes. The early USA produced units electrolyte logo had the appearance of being electroplated. They have a shiny chrome appearance. Later, I am no sure exactly when, they changed the process. Someone with more knowledge may be able to give better insight. I am guessing by units I have seen that this change occurred around mid 1985 as most 16Cs I have seen with the 871B and Class B compliance printed on the back have the non-electrolyte logo. It has a more dull appearance from paint or ink type application. This later tends to be partially to almost completely worn off depending on the state of use.
