    Ciao a tutti,

    we have checked the SM+1 problem on SM5 STPM.
    The conclusion is:

     1) the SM+1 TOHM TTL input signal arrives to ACTEL chip #2;
     2) no output signals on the ACTEL pin 34, corresponding to R9
        CAMAC line (that should be SM+1 bit for CIT trigger pattern)
        was present when performing a CAMAC readout.

     Most probably the ACTEL chip #2 doesn't work properly for the CIT trigger
     pattern, but the time word is O.K.

    A presto,

                         Yiannis, Bob and Nicola
