Omschrijving
Gebruikershandleiding en reference manual voor de HP-28S RPN symbolische calculator.
(Beiden gebonden kopie in het Engels).
Handig om er naast te hebben liggen als je de calculator hebt...
Beschrijving:
The HP-28 was the first calculator capable of solving equations symbolically. They were replaced by the HP-48 series of calculators, which grew from the menu-driven RPL programming language interface first introduced in the HP-28 series.
The HP-28 calculators shares a flip-open (book style) case. On the left side of the flip, there is an alphabetic keyboard (in alphabetic order). On the right is a typical scientific keyboard layout.
The display is a 137x32 LCD matrix, usually displaying four lines of information (3 stack/command lines, plus one softkey label line).
Two models were produced, the HP-28C came first in 1987 with two kilobytes of usable RAM, and was the first calculator with a computer algebra system. A year later, the more common HP-28S was released with 32K of RAM and a directory system for filing variables, functions, and programs.
The HP-28C uses a single Saturn processor at 640 kHz whereas the HP-28S uses a custom chip containing an improved Saturn processor core at 1 MHz (the HP-48S, the replacement for the 28, used the HP-28S cpu core at 2 MHz).
One of the interesting side notes for this calculator is its ability to store significant amounts of information including formulas thereby enabling students to "cheat" on tests.
