We have installed the HAM1 Table Top (TT) L4C FF Infrastructure by building, installing, and restarting the h1seiproc, h1asc, and h1sushtts as documented in LHO:63115.

This will take a lot of work to create / modify the MEDM user interface for this new infrastructure, so please be patient while I get to that next.

However, in the mean time, I'm reasonably confident that the system is totally off, and is not injecting anything into ASC or the RMs because the master switch for all the feed-forward,
    H1:HPI-HAM1_TTL4C_FF_OUTSW
is turned OFF:
    zotws18:~$ caget H1:HPI-HAM1_TTL4C_FF_OUTSW
    H1:HPI-HAM1_TTL4C_FF_OUTSW     OFF

I'm also reasonably confident that the existing system / error signals are not impacted by this system because all the feed-foward / sensor correction is *summed* in to the system, not *multiplied* into the system, so we're merely summing in zero at the moment.

My confidence that this new infrastructure is not blowing up anything once I get through building up the MEDM screen user interface modifications.
