An HP-42SII...Would HP go for it?

[Ángel Martin]

the 42 is a good example of what happens when a (supposedly large or at least including independent sections) development team doesn't align well all its moving parts. The software is perhaps the best RPN code ever made, a clear quantum leap from the 41 and the 15C - yet the hardware enhancements were limited to a saturn architecture and a second line on the display... while removing all the I/O capabilities.

What were they thinking, who knows.... but regardless, with the source code thrown away and its lackluster sales track record it's more than unlikely we'll ever see a resurrected 42 from HP *ever*.
