Ive written to RZL. He says if we have extra chips he can burn them
before we come. The chances of getting a new board before I leave is
basically 0 since Sven is now gone. Besides one should be enough. I
should point out that we have never had problems with the chips
themselves. These modules are relatively easy to fix since they are so
simple. The two problems Chris and I have seen in the past were once
when a connection on the clock chip was bad, and twice when one of the
transistors or diodes driving the ECL/TTL drivers on the output blew up.

Well I humbly suggest the result should be that the highest priority
is given to fixing the stop master. If you unplug the WFDs you are
turning off monopole and LIP physics completely in that SM. Chris and
I are both using this data for analysis. You should treat this just
as if a ERP supervisor went bad.
