HP-42S
From Wikipedia, the free encyclopedia
The HP-42S is a programmable RPN Scientific hand held calculator introduced by Hewlett Packard in 1988. It has advanced functions suitable for those involved in mathematics, linear algebra, statistical analysis, computer science and other applications.
[edit] HP-41 replacement
The HP-42S was released as a replacement for the aging HP-41 series. It was designed to be compatible with all programs written for the HP-41. However, it has received criticism for its lack of expandability, and lack of any real I/O ability, both key features of the HP41 series.
The 42S, however, has a much smaller form factor than the 41, and features many more built-in functions, such as a matrix editor, complex number support, an equation solver, user-defined menus, and basic graphing capabilities. Additionally, it features a two-line dot matrix display, which made stack manipulation easier to follow.
In the HP calculator community, the 42S is infamous for its inflated prices in online auctions.
