p5000etch and pquest updates

Hi all --

Just so you know....   It's been determined that the BCl3 bottle 
installed just last week really isn't BCl3.  The etches were bad and the 
plasma color is off.  We're trying to expedite another bottle.  It 
appears that our supplier has undergone some organizational changes and 
is subcontracting their etch gases -- this is the third etch cylinder in 
the last three months we've received that has been bad.  Needless to 
say, there will be measures taken.  We will update everyone as we learn 

In the meantime, Elmer and Cesar have removed the turbocontroller from 
p5000etch ChA (since there is no BCl3) and placed it on ChB to get that 
up and running.  A new turbocontroller is expected any day, though 
probably moot until we get some BCl3.

Our apologies --
