Ben,

the final test of the A-127 (and all other modules with horizontal pc boards
like A-104, A-143-1/2/3) includes to check if there is no problem with the
pins of the bottom boards and the rail of the frame (for the standard A-100
frame). If there is a problem with the A-127 - i.e. if there is a short
circuit in the A-100 frame (same problem as a few months ago with one of the
A-143 modules) - of course the A-127 will be repaired at no charge.

If this problem happens only with the Asys frame we cannot check it as the
modules are tested in the A-100 frames only.

Best wishes
Dieter Doepfer
