Each cell of the following list gives in its first line links to an online documentation (*.htm or *.txt), followed by a link, to download a zip-file. The *.zip-file contains the tool and the corresponding documentation. Downloading and unpacking *.zip, checking "use folder names", creates the subdirectory *.pic with referenced pictures. Put the cursor on these while reading *.htm to get some additional information. Finally, a brief description of the program is given.

General Tools

Appsman.htm, (10.8 kB), version 3.2003, size on calc 0.7 kB.
Allows complete customization of the 49G/g+ APPS browser and various other built-in menus or choose boxes. Gives the user control on external libraries. 
BZman.htm, (20 kB), version 4.2004, size on calc 1.6 kB.
BZ-compression manager. Most also belongs to OT49 but for those interested in compression only, BZman is the right choice. One can create very small self-decompressing and self-evaluating code. Extra library for the 49g+.
Filers.htm, (36 kB), version 9.2003, size on calc from1.6 to 3 kB.
The package contains 5 filers for the 49G/49g+, which enrich the built-in filer and simplify it at the same time. Filer5 is for the 49g+, with an extra option for convenient data exchange with the SD-card. Main advantages over the default filer: Fast creation of dated HOME backups, hiding/unhiding tools. 
Filer6.htm, (37.5 kB), size on calc 2.2 kB.
The best filer for the 49g+ with a ROM not older than 1.23. Perfect data exchange with the SD-card. And you now can easily create directories inside the card browser.
OT49.htm, (40.4 kB), versions 1.2004 and 4.2004, size on calc 5.1 kB.
Offers library-, menu-, programming- and compression-tools and allows to recall menus, standard or user key assignments, and to toggle fonts, flags and other items. Both for the normal and the advanced user. The library and compression tools of OT49(+) are the best ones available. 
Libman.htm, (24.5 kB), versions 7.2003 and 9.2003, sizes on calc 1.7 kB and 1.9 kB.
There are excellent  libraries for the 49/49+
Gives the user complete control on the LIB key. Libman offers a browser on all attached libraries with various sub browsers. In particular a browser on the library commands itself which show HELP if it exist like in the CAT browser. Allows also listing of all commands of built-in libraries. And Libman+ sets port entry :3: (SD-card browser) at the end of the LIB menu.
espa˝ol Headman.htm, (32 5 kB), versions 7.2004 and 8.2004, size on calc 1.8 kB.
A small library for the 49g+ only, for managing its new header and to apply it in various environments (Stack, EQW etc). Its viewer uses the entire screen and is more powerful than VIEW. In addition, Headman contains convenient tools for reading long documents on the 49g+.
Headman.htm may be read in 2 languages by clicking on the corresponding flag symbol.
Hide.htm, (3.0 kB), version 1.2003, size on calc 0.6 kB.
Permits hiding any files in any directory, e.g., such files as IOPAR and PPAR. Hidden files are known to each command (except VARS). Hide includes a complete Hidden directory management.
Choosext.htm, (18.7 kB), version 9.2003, size on calc 0.6 kB.
Makes the built-in CHOOSE command more powerful by adding an argument for creating a user-defined menu for the choose box, to do more than merely CANCL or OK. User decides on preserving the browser when running a menu option.
Ioman.htm, (26.7 kB), version 4.2004, size on calc 1.4 kB.
A powerful I/O manager. Besides transfer support it sets the parameters in IOPAR and PRTPAR in an easy manner by cycling through all admissible values. In the latest release you can also visualize ASCII control characters, remove dispensable black squares, get the transcriptions of the special HP characters, etc. contains a listing of the first 32 ASCII control characters explaining their original meaning, for download on the 49g+.
Msgman.htm, (10.8 kB), version 1.2005, size on calc 0.7 kB.

franšaisespa˝ol, unfinishedKeyman.htm, (69 kB), version 5.2004, size on calc: Keyman 2.0 kB, Keyman+ 2.2 kB.
Wilhelm Busch, Der Virtuose

Click on the desired flag symbol

Keyman handles mode-sensitive user key assignments. It supports shift-hold and creates two additional key operations: double-clicked and longhold keys. There are lots of examples to explain the use of the commands to the normal user. More is a browser through additional key board tools: switch different key maps in place, clean the internal UserKeys list and packing it by the way, make a key record which runs through various tools like the DEMO library 1234 on the 49G/49g+, and select some top key assignments.

ViewKey.htm, (3.2 kB), version 5.2004, size on calc 0.1 kB.
This minitool displays the current user assignment of a key, for the case you forgot it. Professional assignments (made e.g. with Keyman) are SysRPL programs or code objects. ViewKey cares itself about the right disassembling.  
Topkeys.htm, (10.4 kB), version 4.2003, size on calc 1.0 kB.
Offers some professional key assignments for the 49G most of which are very helpful for the normal user.
Topkeys+.htm, (13.2 kB), version 2.2004, size on calc 1.3 kB.
Similarly for the 49g+. As long as the ROMs for the 49G and the 49g+ are not fully compatible, identical key assignments may not be compatible as well.


Timeman.htm, (25.7 kB), version 1.2005 size on calc 3.9 kB.

TETRI.htm, (16 kB), version 3.2006, size on calc 2.5 kB.
The most fascinating game

What fascinates in this Tetris version is the difficulty caused by the random dice distribution in the first n lines.

Two independent versions make it possible to compete with your partner on the same calculator. 
Mines.htm, (10.3 kB), version 1.2005, size on calc 1.9 kB.
