The HP AC Steady-State Circuit Analysis Pac contains a general purpose Computer Network Analysis Program called CNAP. The building blocks that are available to construct circuit models are resistors, capacitors, inductors, voltage-controlled current sources (VCCS), lossless transmission line segments, open transmission line stubs, and shorted transmission line stub. The program can output the complex ac voltage at any node in the network. Optionally, group delay is calculated. CNAP provides rapid ac study-state analysis of virtually any type of electronic network.

The HP-71 Finance Pac programs have been designed to easily perform the functions of a powerful financial calculator while offering the computer advantages of continuous memory, file creation and storage, and the potential use of peripherals. One program, the time value of money program (TVM), solves a wide range of problems for any person who works with financial contracts of any type: borrowers, lenders, lessors, lessees, accountants, real estate brokers, automobile dealers, and investors, to name a few.

The other Finance Pac program, the depreciation program (DEP), enables you to calculate, display, print, and store depreciation schedules in memory. You can choose from five different methods to calculate depreciation.

The Surveying Pac is a tool to aid the engineer and surveyor in solving many of the common surveying problems. Because it is one large integrated program, and not merely a collection of individual routines, the Surveying Pac exhibits power beyond what you may expect.

Its unique data entry system allows inputs to be made in a variety of ways: by using bearings, north and south azimuths, angles left ot right, and horizontal deflections left or right. You can choose your input modes regardless of the mode of output you desire. If entries are unknown, the program will ask other questions until enough is known about the situation for an answer to be computed.

The HP 82484A Curve Fitting Pac is a powerful tool that enables you to perform functions that are not common to portable computing devices.

The Curve Fitting Pac allows you to quickly and easily choose a model, fit a curve to your data, choose another model, and fit the curve again - all in a matter of seconds.

Your HP 82485A Text Editor can be used to create, view, change, and print source program listings, text files, memos, form letters, personal letters, short reports, and other documents. In fact, the Text Editor enables you to manipulate any text file in your HP-71 memory.

As you compose a text file, you can include (embed) text formatting commands in it. When you execute the format command, these embedded commands determine how your formatted, printed document will look.

The Data Communications Pac provides a versatile terminal emulator software package, the DATACOMM program, for the HP-71 Portable Computer. With this program you can communicate with other computer systems over a phone line to access a variety of information. You can connect to systems such as The Source, Dow Jones News/Retrieval, and other host computer systems via a modem. It is quite easy to obtain stock quotes, send or receive electronic mail, or make airplane reservations using one of these data base services.

The DATACOMM program is entirely menu-driven. Most operations can be accessed from the menu by typing a single key.

In short, the HP-41 Translator Pac allows you to retain the calculator and programming features of the HP-41, and to use your HP-41 programs, as you move into the more sophisticated and powerful world of the HP-71.

Not included in the HP-41 Translator Pac are the time (TIME is included), date, stopwatch, alarm, and extended memory functions from the HP-41CX, or any other functions from HP-41 extension modules. Any HP-41 program that uses functions included in the pac can be translated and run on the HP-71.

HP-41 programs and keyboard operations that are executed on the HP-71 yield the same results as those obtained with the HP-41, except that:

Appendix E contains a list of the HP-41 functions provided by the HP-41 Translator Pac, and description of the differences between the HP-41 and the HP-41 Translator Pac. The HP-41 Translator Pac is based on a FORTH language system built into the pac. FORTH is a computer language that shares many characteristics with the HP-41 user programming language, but is more widely recognized and applied to a greater variety of computers. You do not need to learn FORTH to use the HP-41 translator, but programmers familiar with FORTH can use the system to write HP-71 applications entirely in FORTH.

The SUPER SURVEYOR software was initially developed to fill the need for a data collector which would support the HP-3820A Electronic Total Station. It is now a field measurement system capable of supporting all Electronic Total Stations.

The process of field measurement is facilitated by the SUPER SURVEYOR in its simplicity of concept and use. The functions are kept to a minimum to avoid distracting the user.

The system represent the minimum effort required to perform a data collection or stake out survey. The user is reminded that he is free and possibly obligated to employ any additional methods or techniques which he might judge necessary in the performance if his duty as a Land Surveyor or subordinate.

The HP-71 Development Utility is a program that runs on the HP-71 and allows you to transfer files between the HP-71 and another computer called the "host."

An HP-71 Development Utility work station is the equipment and software that allow you to transfer files between the HP-71 and a host.

This document is a 'cookbook' for applications programmers working with the HP-71. Two goals are envisioned: first to serve as a timesaver, and second to suggest a measure of consistency among programs written for the HP-7I. While there is no hope of addressing all possible applications on the HP-71, common subjects such as user interface, environment preservation, and error trapping are discussed. The specifics of each application are left to the programmer.

WorkBook71 is a data-gathering, analysis-and report-generating tool for the Hewlett-Packard HP-71 Portable Computer. Modules of the system include Editor, data format converter, searching, and Report Formatter. Each module can operate separately of others in the group and, by virtue of data format conversion, other programs you may have can be used interactively. The goal has been to provide a versatile package in which data can flow between applications with minimal hassle.

This manual is in several sections. "Getting Started" should be read before investigating the programs in this package. "Using the HP-71" is as much about a philosophy of using the computer in general as it is about using it with this package. There is a section on each of the programs with a discussion of their purpose, usage, and a list of commands. Part 5 explains the structure of WorkBook files and discusses methods for using the data in your Basic programs. Part 5 need only be read if you plan on writing your own programs. The inevitable Addendum is in the last section, listing some cautions and hints. A glossary is at the back of this manual.
