I've uploaded a new PC Transputer Emulator Version 5.3.
The new version can be found on my website:
http://sites.google.com/site/transputeremulator/
The new files (within Emulator Files.zip) are attached at the bottom of the Installation Instructions page. See what's happening (on my website) for fixes and additions in version 5.3.
The source code is also available for viewing on the Source Code page for those intrested.
