Repair update

[Dick Crane]

Ag4108 users, good news/bad news:

The ag4108 should be functional (not melt wafers) by this time tomorrow. 
The control system will change.

We will be changing the  control system from the original, ag4108 
version, to an Allwin21 control system identical to the ag4100. This 
change will allow, among other things, the use of obtainable pyro 
control boards (our current parts problem). Users will need to be 
retrained (refreshed) on the new, simpler to use system. New procedures 
are being written.

We appreciate your patience,

Dick
