The Museum of HP Calculators
Downloadable HP-41 Programs
These programs were loaded into an HP-41C via magnetic cards or bar codes
and then uploaded. At this time, no one has taken the time to rewrite the
documentation for these programs as HTML pages. To use these programs, I
suggest studying the listings, running them, and if they still fail to make
sense, many, but not all, are documented on the
Museum CD set. Please check the
list of manuals before
ordering. Volunteers to write up the
documentation and to scan missing manuals are always appreciated. No support

There are six basic methods: You only need to do one of the 6. (The
first three methods require an HP 82160 HP-IL interface in the calculator.)
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

on the download via the serial interface, please see Tony Duell's
Port downloads article.

Leo Duran's User-Code File Converter / Compiler /
De-compiler / Bar-Code Generator or Dan McDonald's
"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
