Installed a brand new loadlock controller with new EPROM.  The 
controller is not even powering up now.  The new controller is behaving 
like the other two controllers.  Checked voltages inside the 
controller.  The +5V and +/- 15 V checked OK.  The 24 V is a little low 
at 23.05 V but I think its OK also.  Verified that jumper settings were 
the same as the original controller.
Spoke to Graeme Wheeler (STS director of US op) about field service.  He 
said that they should have somebody available early next week.

    The STS field service engineer has been working on the etcher since 
8/10.  So far, he has not he has not found anything significant.  We 
have replaced a power supply module,  a motor driver IC , a set of 
backup batteries and new load eproms for the lock controller.
    The current plan is to obtain a complete set of schematics from the 
UK and continue to troubleshoot.  We should have the schematics by 
tomorrow.  We also sent one of the loadlock controller back to the UK 
for failure analysis.
    Sorry that I can't even give an estimated up time since we have not 
yet determined the cause of the problem.
