all HP48 related RPL/RPN material will fit fine, if you don't mind searching for hidden keys and menus. As a regular HP product, at least for now, there is none. Anyway, there is a two-volume book named Science and Engineering Mathematics with the HP 49 G, by Gilberto Urroz (try, bookstore, search). I am waitting for mine and I bought them because they were very well recommended by contributors in here. In time: I cannot tell you this publication covers RPN/RPL specific matters, but it seems to have a lot of good material.

If you wanna try...

What about the HP 49G Advanced User's Guide and other manuals which can be downloaded from

I have not found yet a better source of RPL-related material that would fit in the HP49G's RPL structure than the ones written for the HP48G series. I downloaded and printed the Advanced User's Manual and it was not THAT much helpfull; indeed, it has a lot of info about using an HP49G in algebraic mode, and some reference to its use in RPL/RPN fashion.

Is there anything else that can be downloaded? I do not know anything about them. Would you help me, too? Just a hint of some titles, so I can have and indicate them.

Thank you and best regards.

I just got my 49G a month ago, so I'm not an expert. I have the 48 manuals and I will take your advice. I agree the 49G AUR continues the regular user's guide emphasis on algebraic mode.

I downloaded a file from called "20 Essential Things to Know About the HP-49G: A guide for the hopelessly confused!" ( It is a little out of date - it says you can download the HP49G AUR from, which you can't, although you can get it from It lists a number of books including the one by Urroz that you named, also several books by Eduardo M. Kalinowski that can be downloaded: 48G UserRPL and SysRPL that apply to HP49G, and 49G SysRPL. In addition it lists several websites including one which has a CAS manual which you can download. I also downloaded a pocket guide fom (I didn't get one with my unit).

Also, has an FAQ, a number of lists of commands and such by Joe Horn, and a number of ROM images including 1.19-6 which seem to be the recommended best one to use, although as far as I can tell, you can't get it from because it is not released.

I'll add that the newsgroup comp.sys.hp48 is a good place to add questions about the 28 series, 48 series, 38G, 39G, 40G, and 49G. You can search the newsgroup archives at or just browse at Google isn't up-to-the-minute with its updates, so to participate it would be better to use some other method, such as or the server with your own newsreader.

Not that there's anything wrong with this forum; but the museum is mostly for out-of-production models.


Thank you, both.

thank you, Ellis and James; good source of reference.

Sometimes we do not find the time to delve into some sites and find what you have found.

This is golden info. Thanks for sharing.
