VMS Mosaic 4.2
Posted by Ian on Monday September 03 2007 @ 12:49PM EDT
Thanks to George Cook, version 4.2 of the VMS Mosaic web browser is now available.


VMS Mosaic is a GUI web browser. It supports HTML V4.0 (including tables and frames), animated GIFs, cookies, secure connections, etc. It does not support Java, JavaScript or style sheets. A C compileris required to build it.

Executables built on VAX/VMS (5.4-3 and 7.3), on Alpha VMS (7.3-2 and 8.2) and IA64 (8.2-1) are available at:


These executables are unlikely to work on versions of VMS older than what they were built on, but they should work on newer versions.

The most significant changes in this release are:

1. Simultaneous inline image loading
2. Support for JPEG 2000 images.
3. Support for a few common JavaScript functions
