Introduction (owner manual extract)
Congratulations! You have purchased the HP-71, an advanced computational tool that works as easy as a calculator but is as powerful as a computer. The rugged design and high performance of the HP-71 can substantially increase your productivity.
The HP-71 offers you the following features:
Small sized and battery powered for maximum portability.
A special calculator mode for performing sophisticated computations while viewing intermediate results.
A powerful set of BASIC functions, statements, and operators - over 230 in all. Many larger computers don't have a set of BASIC instructions this complete.
Advanced statistics functions that enable you to perform computations on up to 15 independent variables.
Recursive subprograms and user-defined functions, which are usually found in other programming languages, now extend the power of BASIC in the HP-71.
An advanced internal file system for storing your programs and data. The HP-71 has continuous memory. When you turn the computer off, it retains programs and data.
A keyboard that can be easily customized for your specific applications.
Optional extensions for your HP-71 include application modules containing prerecorded, ready-to-run programs, a magnetic card reader for low-cost storage and retrieval, and an HP-IL interface that enables you to add printers, a digital cassette drive, a video interface, a modem, and other devices to your portable computing system.

Introduction
Emu71/DOS is a software emulator of the HP-71B machine and HP-IL system. It runs under DOS or in a command box under various 32-bit Windows (95,98,2000,NT,...). It can run on 64-bit OS using a virtual DOS environment.
Main features:
- Text mode application consistent with the HP-71B system look and feel
- Very fast: the emulation engine is written in optimized assembly language
- Runs correctly even on slow 186 (e.g. HP200LX), 286 systems at reduced speed
- Compatible with cut&paste operation in Windows environment
- Can emulate any number of ROM or RAM modules
- Support of 64K and 128K modules
- Emulation of the HP-IL loop and 8 HP-IL devices
- Support of the PIL-Box and of the ISA HP-IL board
- Direct access to LIF image file archives with support of disc volumes up to 16 MB
- Supports 43/50 lines video modes

Emu71/Win : HP-71B Emulator for Windows
By Christoph Gießelink
![[Image: emu71win-computer.jpg]](https://www.hhcworld.com/files/HP71COMPENDIUM/IMG/emu71win-computer.jpg)
Introduction
Emu71 is based on the sources of Emu48 and is an emulator for the Hewlett Packard Titan calculator HP-71B hardware. This calculator emulation is based on the 1LK7 Saturn CPU, the 1LF3 display driver, the 1LG7 ROM and 1LG8 RAM chips. The calculator emulation can be expanded by the emulation of additional RAM and ROM modules and by simulations of the HP-IL module inside the ports 0 to 5. The emulator is running on all Win32 platforms and is published under GPL.
Main features:
- Pure Win32 program / sources could be compiled for pure x64 program
- Graphic mode application consistent with the HP-71B system look and feel
- Skins for different appearance (two included)
- Look&Feel and keyboard can be defined through KML
- Multi instance / multi session ability, each session is saved in an own document
- Slower than Emu71/DOS but of course a lot faster than the real calculator at calculations
Simulated graphic display with possibility of contrast, blinking and row driver programming, but limited to the regular 22 characters display output is much slower than Emu71/DOS because scrolling and other relevant display output timings are controlled by the calculator firmware and so have the same speed than the original calculator
- Exact simulation of the original memory layout (16KB build with 16*1KB chips)
- No limitations in RAM / ROM configuration
- Can emulate any number of ROM (hard or soft configured) and/or RAM modules
- Diagnostic ROM works
- Emulation of the HP-IL loop with support for TCP/IP (v4 & v6) communication and for the PILBox
Allowing multiple HP 82401A HP-IL Interface modules (HP 82402A Dual HP-IL Interface simulation, but not limited to only two interfaces)
Some of the files included in the Emu71/Win distribution package:

HP-71X : HP-71B Emulator for HP-48GX/49G/49G+/50G
By Zeljko Hrastovcak alias HrastProgrammer
![[Image: hp71x.jpg]](http://www.hrastprogrammer.com/hp71x.jpg)
Introduction
The HP-71X is an HP-71B Extended MicroCode Emulator for HP-48GX/49G calculators. This famous vintage calculator is fully recreated because I emulated the real CPU behaviour and the emulator executes a code from the real HP-71B ROMs. Beside the emulation, I added various advanced features to the original specifications.
There are four variations of HP-71X according to the various calculator configurations and different user needs.
These are:
HP71X48: The EXTENDED version for HP-48GX with one or two 128K RAM cards in either Slot1 or Slot2 (card in Slot2 can be >=128K, of course). Uses one card for the HP-71B/Emulator ROM with 33.5K RAM (Port #0) and (eventually) the other card for additional 128K RAM (Ports #1..#4) giving the total of 161.5K freely configureable RAM. Forth/Assembler and HP-41 Translator ROMs can be loaded to Port0 of HP-48GX (Port #5 inside HP-71X). Furthermore, additional 64K of non-configureable RAM (Ports #5 and #6) and 32K ROM containing MATH ROM (Port #7) can be loaded to Port0 instead of Forth/Assembler/HP-41 Translator ROMs. The emulator automatically configures itself according to the installed components.
HP71X48D: The DEMO (17.5K RAM) version for HP-48GX with only one >=128K RAM card in either Slot1 or Slot2. Uses this card for the HP-71B/Emulator ROM with 17.5K RAM (Port #0).
HP71X49: The EXTENDED version for HP-49G. Uses Port1 for both the HP-71B/Emulator ROM with 33.5K RAM (Port #0) and (eventually) additional 128K RAM (Ports #1..#4) giving the total of 161.5K freely configureable RAM. Forth/Assembler and HP-41 Translator ROMs can be loaded to Port0 of HP-49G (Port #5 inside HP-71X). Furthermore, additional 64K of non-configureable RAM (Ports #5 and #6) and 32K ROM containing MATH ROM (Port #7) can be loaded to Port0 instead of Forth/Assembler/HP-41 Translator ROMs. The emulator automatically configures itself according to the installed components.

HP-82400A Magnetic Card Reader
![[Image: HP-82400A_TV1_MINI.jpg]](https://www.hhcworld.com/files/HP71COMPENDIUM/IMG/HP-82400A_TV1_MINI.jpg)
Owner Manual Introduction
The HP 82440A Magnetic Card Reader provides mass storage for the HP-71.
Modified extract from HP Journal June 1983 HP-75 Card Reader Article
The card reader uses the same technology as the HP-75 portable computer, the handpulled magnetic card reader/writer can store 1.3K bytes of user data or programs per card. The cards are 10 inches long and 0.375 inch wide. Handpulled refers to the lack of a motor for transporting the cards past the head. Instead, this function is performed by the user. The user initiates a card operation with the appropriate command, inserts the card into the card reader, tells the HP-71 that the card is ready by pressing the RTN key, and then pulls the card through the card reader

HP-82402A Dual HP-IL Adapter
Owner Manual Introduction
The HP-82402A Dual HP-IL Adapter allows two HP-82401A HP-IL modules to be plugged into the HP-71B simultaneously. When inserted into the HP-IL port of the HP-71B, the Adapter significantly expands the range of manufacturing and portable data acquisition settings in which the HP-71B and HP-71B systems can be used. The HP-71B treats each HP-IL module as a separate, and totally independent interface.
This allows the HP-71B to operate either as:
- A controller on both HP-IL loops
- A controller on one HP-IL loop and a device on the other
- Or, a device on both HP-IL loops
The Dual HP-IL Adapter is passive; all the firmware for controlling two HP-IL loops is already built into the HP-82401A HP-IL modules.

ZenWand-71 Barcode Reader by Zengrange
![[Image: ZENWAND71_TV1_MINI.jpg]](https://www.hhcworld.com/files/HP71COMPENDIUM/IMG/ZENWAND71_TV1_MINI.jpg)
Owner Manual Introduction
A Barcode Reading, Analyzing and Printing System for the HP-71 Handheld Computer.
The Zengrange ZenWand has been designed for the Hewlett Packard HP-71 Handheld Computer to provide a completely portable bar coding system using the Hewlett Packard HBCS-2200 Barcode Reader wand. The product has been further enhanced by a powerful, but uniquely friendly operating system, designed by Zengrange Ltd. Not only does this operating system cope with current requirements, but it is also capable of being further extended as new barcode decoders and printer types become available.
As delivered, ZenWand decodes the following ten kinds of barcode:
- Codabar (USD-4)
- Code 11 (USD-8)
- Code 3-of-9 (USD-3)
- International Article Number Codes (EAN-13, EAN-8, UPC-A, UPC-E, UPC-E(l))
- Industrial 2-of-5
- Interleaved 2-of-5 (USD-1)
Each barcode type read by ZenWand is decoded by string functions, i.e. the barcode is returned as a text string. These functions permit the returned string values to be processed directly by the user's own application programs, stored in files in memory, transferred via HP's Interface Loop (HP-IL) to mass storage media or downloaded to host computer systems via IL-modems and IL-interfaces.
The ZenWand system is further enhanced by the inclusion of functions for:
- automatic discrimination of barcode type,
- check digit verification,
- barcode analyzing, and
- printing of barcodes on the HP-2225B Think Jet Printer.
