Introduction
Described in one HP brochure as 'Unsurpassed in terms of software, expandability and versatility, these are the calculators that grow with your needs.' The HP41 series of calculators were considered by many people to be the ultimate calculator.They sold in massive numbers, had vast software support, spawned user groups like HPCC andwere even used on the Space Shuttle.
The HP-41C was launched in 1979 and was a quantum leap over previous programmable calculatorsdue to its alphanumeric capabilities and unique user interface. It had 63 registers which could be divided upbetween program space and storage space. Single memory modules adding blocks of 64 registerswere available allowing up to a maximum of 319 registers but doing so prevented the user addingROMs or peripherals. The 4 expansion slots could be utilised to drive a printer or acceptprinted programs from barcode or allow the addition of a magnetic card reader.
HP's first attempt at correcting this problem was the Quad memory module which allowed full expansionof user memory whilst using only 1 slot. A better solution came in the form of the HP-41CV whichhad the full 319 registers built in.
The addition of the HP-IL interface loop allowed theaddition of printers, digital cassette drives, plotters, multimeters, modems,video interfaces and a host of other peripheralswhilst only occupying 1 slot. This left the other slots for ROM modules which could containprograms on virtually every (mathematically based) subject you could think of.
Perhaps the most interesting HP produced modules were the Time module and the Extended Functions module.Amongst other things the Time module allowed alarms to wake up the calculator and run programs allowing for example the system to becomea control unit in data collection applications using inputs from devices connected to the HP-IL system.The Extended Functions module provided a RAM disk system allowing program and data files to be storedand manipulated in extended memory (some of which was included in the module). HP supplemented thiswith additional Extended Memory modules providing additional non-volatile storage on the machine.
The HP-41CX then came out containing the capabilities of the HP-41CV plus the Time and Extended Functionsmodules plus some other unique features like a Text Editor for ASCII files in extended memory.
HP also ensured that the HP41 remained competitive against newer more mathematically powerful calculatorsby bringing out the Advantage Module which added some of the financial functions of the HP-12C, complex number and matrix handling like thoseon the HP-15C and computer science funtions like those of the HP-16C. When the next generation ofcalculators added Infrared printer support, HP brought out the 'Blinky' module.
Finally discontinued with the introduction of the HP48SX the HP41 series remains a testament to thepeople who developed it. A classic in its own lifetime.
Many more details of the HP41 series can be found in the HP Calculator Museum.

Documentation
These programs were loaded into an HP-41C via magnetic cards or bar codesand then uploaded. At this time, no one has taken the time to rewrite thedocumentation for these programs as HTML pages. To use these programs, Isuggest studying the listings, running them, and if they still fail to makesense, many, but not all, are documented on theMuseum CD set. Please check thelist of manuals beforeordering. Volunteers to write up thedocumentation and to scan missing manuals are always appreciated. No supportis available.

Hp-41c User Manual Pdf
There are six basic methods: You only need to do one of the 6. (Thefirst three methods require an HP 82160 HP-IL interface in the calculator.)
Hp 41c Modules
- Download the Binary (.raw file), transfer to calculator via the HP 82973 PC HP-IL card. Requires appropriate PC software such as HPLink or Trans41. HPLink runs correctly only on older/slower computers such as 286 machines. These can be found in thrift stores, second hand stores etc. for very little money. Trans41 is a product by Eclipse Logic Inc and Tacit Logic Systems. This company seems to have disappeared but some HP collectors have the program and find that it runs well on fast PCs. (If you happen to have a contact for these companies, please let me know and I'll ask permission to post the software here.) Please see Leo Duran's User-Code File Converter / Compiler / De-compiler / Bar-Code Generator article and Dan McDonald's HP-IL Files: Where, What, Why, How, etc. article for details of the download. (These .raw files do not require you to remove the LIF file header before downloading.)
- Download the Binary (.raw file), transfer to calculator via and HP 9114 disk drive and LIFUTIL. The freely available LIFUTL allows the PC to read/write the disks read by the HP 9114. Please see Leo Duran's User-Code File Converter / Compiler / De-compiler / Bar-Code Generator article and Dan McDonald's HP-IL Files: Where, What, Why, How, etc. article for for details of the transfer.
- Download the Hexadecimal file (.dat) and transfer to the calculator via the HP82164 HP-IL to RS232 serial port interface. Requires a HP82164 HP-IL to RS232 serial port interface and an Extended I/O module. For instructions on the download via the serial interface, please see Tony Duell's Serial Port downloads article.
- Download the Binary, print barcodes, scan with the wand. You may use Leo Duran's User-Code File Converter / Compiler / De-compiler / Bar-Code Generator or Dan McDonald's HP-41C 'Decompiler' and 'BarCode Maker' to print bar codes which may then be scanned. Leo's program has the advantage of not requiring Excel but only runs on PCs. Dan's should run on anything that can run Excel and use TrueType fonts.
- Download the Barcodes in Adobe Acrobat (.pdf) format, scan with the wand. This option is available for a limited number of programs. If you don't have an Acrobat reader, readers for many platforms may be freely downloaded from Adobe.
- If you have none of the above hardware, key in the program from the listing.
