Hal R. Brand <BRAND@addvax.llnl.gov> is said to have a VMS save set with a ready-to-run VMS version of Emacs 18.55 for X Windows. It is available via anonymous FTP (addvax.llnl.gov). It is possible that the VMS versions of Emacs at other sites have X support compiled in. See etc/FTP for locations.

Getting Emacs to run on VMS with DECwindows requires a number of changes to the sources. Fortunately this has been done already. Joshua Marantz <josh@viewlogic.com> did most of the work for Emacs 18.52, and the mods were ported to 18.55 by Johan Vromans <jv@mh.nl>. Also included is the handling of DEC's LK201 keyboard. You need to apply the changes to a fresh Emacs 18.55 distribution on a Unix system, and then you can copy the sources to VMS to perform the compile/link/build.
The set of changes have been posted a number of times three times the last 12 months, so they should be widely available.
