Rolf, Jim and Dave. We have created RCG tag 2.8.5 from branch 2.8. This version has the bug fix to disable the 18bit DAC Anti-aliasing chassis when the new timed DACKILL part is activated. 

2.8.5 also has two dataviewer changes, these have already been installed at LHO by Jim prior to this release.

I have set the rcgcore and lho/h1 release pointers to use 2.8.5. All model builds from now on will use this release.
