Converter does not have support for SGI operating system

The following pages have links to many demo
applets which appear to have been put through the automated HTML
Converter, so they have JavaScript code which only generates correct HTML
for the Netscape Java plugin on certain operating systems (Solaris,
Linux, AIX, OS/2, etc.) and defaults to using the normal <applet>
tag otherwise:

Could someone there please change the JavaScript
code to account for the Sgi's Irix operating system as well?
