The HP 39/40 calculators do not offer a RPN calculation mode, which otherwise is a hallmark of HP calculators. This program implements a scientific RPN calculator providing a four-level RPN stack and the real number functions of the HP 39.
Al Bhed is a language spoken in the Playstation 2 game final fantasy X. To translate this language to English you have to collect primers. These magazines are scattered all over Spira. If you missing a lot of primers or you have just begun your journey and you want to know what the Al Bhed say to you, use this program.
This program is based on the 'Blood Alcohol Concentration Level' as it will calculate your BAC Level when you enter your details and required vars, i.e.: drink type. Blood Alcohol Concentration Level is a way of finding/measuring the amount of alcohol in your blood stream. (It's best to stay below .1)
An e-book written by Preston Chaderton. The story goes about an exiled Neo Wolf trying to avenge the death of millions of people by invading his enemy's base. Not finished yet, but will be soon.
Grob filer is an excellent grob manager. It has the ability to copy, erase, view and encrypt grobs. Its downside is that is written in User RPL, thus slower.
RPN simulator for the HP 39g+ series. Function wise, it is an equivalent of between an HP 35 and 45. Programmed in basic, and can be run from any applet.
Possibly one of the best monochrome GROB editors. Contains various files, including English and French versions in both library and variable format, along with source code. English translation by Fin; HP 38/39/40 port by HP-Poska.
Lets students work with matrix calculations as quickly as possible. When it starts, it displays a list of matrix calculations you can perform (add, subtract, inverse, etc.). After choosing one, the program asks you for two matrices, namely M1 and M2. Once that's done the answer is automatically displayed and stored in M1. I've even programmed it to detect when certain calculations aren't possible. While this may sound like a lengthy process, it does take place a lot faster.
Allows you to set the internal keybounce time to either reduce accidental double-presses of keys or increase the speed at which you can press the same key twice.
System RPL library for the HP 39/40. Provides 36 new functions, including hex/dec conversion, physical constants, unit conversions, time and date functions, calendar, time value of money, and a few EE functions. Also has a number of functions useful to programmers.
This is one of those "must have" aplets for students who solve problems involving borrowing money and making regular repayments. Once you have it on your calculator all you have to do is store the amount borrowed into P, the interest rate in to R and the amount being repaid into A and the aplet will then show you the remaining principal and interest charged each year/month/quarter.
This program tells the time and date that are set up on your calculator.
Might be used as some sort of protection against people who do not know how to use HP calculators.
A collection of music files, two of which are written by Colin Croft and the others by unknown programmers. Songs are: Flintstones, Dumped Again, Blister in the Sun, Mary Had a Little Lamb, Nick's Song, Happy Birthday, Charge, Funeral March, Come As You Are, Happy Birthday (II), Star Wars, Hymn 389.
This program stores the information about people on you calculator based on three scales: soul, brains, and body. Requires some program writing ability, what you will need to do is explained in the file.
This software is designed to calculate dates on the HP 39/40G, including the number of days between two dates and the date = date + number of day. A small integrated database will allow you to integrate your family birthdates or your preferred dates.
This aplet converts your 39/40 to a complete RPN scientific calculator, it has the classic 4-level stack plus LASTx. It's written in System RPL and runs with no noticeable lag. This version supports real numbers only.
This is an ingeneous and excellent add-on that is basically a really neat total waste of time :-) When you download the library to your calculator it will put a ticking clock at the bottom of the HOME view. It displays both the date and the time (once you've set them) and uses both 12hr and 24hr time format and both US and European date format.
This aplet displays your timetable (up to seven periods.) To set it up you will need to edit one of the programs and add a number for each of your subjects, then enter these numbers into Matrix0.
You may be aware that one of the problems with the HP39G and HP40G is that whole rows or columns of keys will occasionally stop working. If you can still access the APLET view and the screen keys then this aplet will transfer you into the Program or Note views so that you can use SAVE/RECV to save them to a PC (assuming that you have a cable) before getting your calculator replaced.
This is a library that kills other libraries! Libraries are small attachments of machine code that come with some aplets. You can see if you have any on your machine by pressing SHIFT MEMORY and looking under the Library heading. Most of them automatically delete with their parent aplet but some don't and there's no way to delete them then. This library will do it. Just note the decimal number next to the library in the MEMORY view and then type UNLIB(number) in the HOME view. Providing that it's not in use then it will be gone. You can't delete the UnLib library itself but since it's only 189 bytes in size that hardly matters.
Views the note file of any aplet in the calculator's smallest font, allowing much more text to be viewed on the screen. The drawback is that it is a little slow. Simply run the program to view the note file of the currently selected aplet. Requires L1542.
