Re: Are older 12c's as high quality as 15c's? Message #2 Posted by Nelson M. Sicuro (Brazil) on 23 Nov 2003, 8:46 p.m., in response to message #1 by Josh P
I have a HP-12C with the flexible circuit board and a protective "envelope" around all circuit. Is very well made, build in 1983 in USA. I had a identically well made HP-15C made in Brazil back in 1983 (bought new, sold in 1989 to buy a 42S). These old ones have in the battery compartment two single foiled springs.
The newer HP-15C and 11C that I have doesn't have the protective "envelope", and the circuit board is rigid with the chips, display and keyboard alltogether. These newer ones have in the battery compartment a helical spring in one side and a golden squared contact in the another side.
The HP-12C suffered several other modifications, that I don't know yet.
In short, the first "Voyagers" are all the same quality. The entire line followed the same modifications (I heard that the 12C ones where the first to be "upgraded") until they take the 10C, 11C, 15C out of busines... :(
Anyone to confirm this?
Best regards,
Nelson
