I just found this from Paul´s link on a surveyors forum. Thanks so much. What a great tool to have on the desktop.

I just D L this and I love it! I am a surveyor and the 41CX was always my favorite. I noticed though that it only has 218 registers available for programming.
Is there an add on that will expand the register limit or is 218 the final cap?
BTW.. Thnks for doing this :)

I don´t believe any such FREE manual exists. However, the Hp website has a way to navigate to the calculator section and you can download tips and sample program modules to learn from. They are pretty good (not a manual though). If you want the real manual, it is available from the Hp museum via purchasing a CD (which includes dozens of manuals, one of which is for the Hp 20s). I believe it is around $10-15.
The Hp website approach should be enough for you to start and use the calculator to its fullest advantage.
If this is your first experience with this calculator, remember it is an AOS calculator, not an EOS calculator (and NOT RPN). So modern calculator manuals are of little use to learn how to use or program this calculator. I personally like AOS better than EOS, but the current majority of calculators are now EOS.

If you used it in algebraic mode, the Hp 19B and the Hp 18c (no trig and 1 4th the RAM) are very similar.
The Hp 17Bii (any flavor) is the most similar that is readily available for feature set and function. Doesn´t include trig or units conversions and obviously has a different layout. However, has the timer, same business functions, same solver, same menu system. The newest Hp17Bii+ also has 4X the RAM (32K) so that it can hold hundreds of equations (probably not a practical plus as the machines have a tendancy to lose memory on battery changes).

I´m trying to find this calculator. I know it´s no longer made. If you know any shop that might have one, please contact me.

Thanks so much for the tip on the paperclip to reset the HP 19BII. This sort of info should be in the Owners Manual. I can´t help but wonder how many have been thrown away because the display would not come up after replacing batteries. Thanks Again!!!!!

Samsone cables used to carry battery doors. The Battery door you request is for a calculator that was taken off the market nearly 20 years ago. Hp is only obligated to support or supply parts for five years. If Samsone cables doesn´t have any left, you can buy an Hp 18c, 28c, or 19B series calculator and steal the door off of one of them.
I will send you an email to follow up.

example: R500 payment for year.
R500 (payments) increases with 10% yearly
Interest earned is 5% yearly
what is the total value after 5 y?
I just bought a HP20b Business Consultant and have problems with above type calculation.

Hp never repaired this line of calculators, simply replaced with another for the 1st year of warrenty. There is a company in the USA that does fix this calculator for a flat rate at " fix that calc " google to find.
The display is now rather rare and their wait period is long. I really suggest you buy another calculator. The new Hp17Bii+ has more memory and is readily available from the USA from hpcalc.org. He sells overseas for minimal markup ie postage.
Or buy another Hp17Bii from ebay or other used market. That is actually my first suggestion as the older Hp 17Bii is extremely well built and I do not know how the newer Hp 17Bii+ compares in quality (it does have 4X the memory, but I have never had use for even the 7K of RAM in my Hp 17Bii).
In reply to Juan Anonio E. Munoz:
I recently bought from Office Warehouse an HP 17bII financial calculator. My query however is about my HP 17BII which I purchased in Singapore (I think) sometime before 1990.
The LCD on said calculator turns somewhat reddish and I have to rotate it somewhat to see the information in the display.
I called up the repair center of HP Philippines. They, however, claim they do not repair handheld calculators because they have no capability to do so. They suggested I get in touch with some HP service providers but who likewise cite they do not service HP handheld calculators.
Above statements from both the HP repair center in the Philippines and its service providers, however, runs counter to the statement in the manual of said calculator which cites that HP has offices worldwide which have the capability to repair the calculator during and after the warranty period.
Would appreciate therefore receiving information on how I can go about having my old calculator repaired.

Yes, the Hp 17b´s solver allows you to have as many equations as the memory will allow. In the case of the 17Bii+ that will be close to 500 equations of moderate complexity. The problem with the solver is simply keeping track of the hundreds of equations that you can conceivably save. They fall into a list of equations and you should probalby start each equation something like this:
Slope: Y=m*X+b
Next eq: LongName=Anything+Else
The front portion is an identifier that you will want to use if you have multitudes of equations to save. If you want to segment your equations into groups, simply edit and save while you are between two equations. That should save your new equation just below the last equation on the stack.
In reply to Brian Thomas:
With the HP 17bII+ Can you enter and save multiple equations using the "SOLVE" command? For example, I´m looking to save two equations (i.e., a growing perpetuity and a growing annuity). Can this be done?

I am using a HP 10bll to calculate standard deviation. How does one enter a negative number? Is this entered by placing a -before the decimal? The result was 0.91 which seemed too high.
