I have the x1sushxts05 model running now. 

In X1SITEMAP_TRIPLES.adl, the macro substitution used for the 05 models used FEC=17 instead of FEC=18.  I changed the macro to use FEC=18 for both HLTS05 and HSTS05, which allowed me to open a working X1SUSHXTS05_GDS_TP medm screen.  This in turn allowed me to press the BURT button after the X1 IOC started, which allowed the model to continue to run.

It's been broken for quite some time, so I don't know why the wrong FEC number was in the X1SITEMAP_TRIPLES.adl file.

I note that there appears to be an excitation test point 119 that shows up on the GDS_TP screen.  When I run diag, it indicates no test points are set, and no excitations are running.  Not sure where it's coming from, but if it bothers you I can try harder to get rid of it.  It'll probably involve rebooting stuff.
