From this very moment the software can be downloaded from the server. I switched from a download-based fee to web-page advertizing. The resulting revenues are primarily used for maintainance of this web-site and my non-profit decompression medicine research, which in turn will lead to safer diving procedures for the whole diving community. Please read the licence statement before you use the software.
Multilevel 1.9 PDA is the second international release of
decompression software and also the first version especially designed
personal digital organizers (PDA).The first German version dates back
1996. It all started with an MS-DOS version, much like the famous "Dr.
X". Several Windows - version were released afterwards, written in the
powerful but platform- dependent C++ - programming language. In 1998
Java Revolution provided the world with the fascinating possibility of
a platform-independent programming language. I soon realized the huge
and converted my source code to Java. It was well worth the
and I am sure, never to return to the C++ - world. Meanwhile I have the
great pleasure, to provide the diving community with the first
mixed-gas decompression software that is running on different platforms
like Windows NT/95/98/XP/Vista, Windows CE/mobile, Linux, MacOS, Unix
In 1999 the first international version of Multilevel (version 1.6) was released.
Multilevel 1.9 PDA is remarkable in that it comes with a number of very useful features:
Attention: Multilevel has been tested with various operating systems and WWW-browsers, but problems might possibly occurr, since I have used the AWT- and not the (truly platform-independent) Swing - classes because the program had to be able to run on a simple WWW-browser under Java 1.02. Although the software has generally proven to be platform-independent, the GUI might have to be altered on particular operating systems. This can most probably happen with handheld PCs with small screens, operating on systems like Windows CE/Mobile or Palm OS.
However, generally speaking, the availability of JVMs on even exotic operating systems is steadily improving. Java has meanwhile earned a reputation of running on a lot of different consumer devices from mobile phones to Network PCs and has become more accepted than ever before. Please give me some sort of feedback on which platforms you have successfully tested Multilevel.
There can be no doubt that one of the most powerful platforms for Multilevel 1.9 PDA is the Sharp SL-5500, called "Zaurus".
Since Linux and Java are already on bord, this powerful handheld is certainly the best choice if you want to run Multilevel on a PDA.
Until this very moment the following platforms have proven
|Operating System||Java - Environment||Remarks|
||Netscape, Firefox (Java Plugin), Internet Explorer
|Windows CE/Mobile||Microsoft JVM||on Casio's Cassiopeia|
|Embeddix||Jeode JVM (preinstalled on the "Zaurus"!)||Runs flawlessly on Sharp SL-5500|
|Linux||Netscape Communicator 4.x or greater
|MacOS||Netscape Communicator 4.x or greater
Check http://java.sun.com to find
a JVM for your platform. Please let me include your experience with Multilevel on this site!
