But the first requirement would be strict conformance to the spec. Yes, which pretty much rules out everything except xterm. :-) xterm had DEC people involved, so I have at least some confidence that they might have checked it against some specs, and not just made up their own assumptions. I had a good look at the xterm source code to see how difficult it would be to use it as the basis of a decent java-based terminal emulator. 'There be dragons' was as far as I got... My second thought would be to write an simulation of a VT320 which was capable of running the VT320 ROM. That seems like a pretty good idea, but that's as far as it's got. There is an terminal emulator called VMSTAR in the Freeware V5.0 archive which some of you may remember - apparently this takes that exact approach.
