This morning, the 'additive' Jameson gave to H1:ISI-BS_BIO_IN_BIO_IN_TEST was still in place and giving a fault to Stage1 V3 Status.  I removed it and it has remained good since except during our testing.

Historically, this has not been glitchy for the past 60 days.  The CD BIO IN must be bad for 10 seconds before the ISI WD triggers and that first occurred at 1230 PDT yesterday.

Around 9am today, monitoring the output from the BIO Chassis going to the I/O computer, the indications were that the V3 channel responds the same as others with very similar logic voltages when the input from the CD was present and absent.  Not terribly satisfying but maybe suggesting the BIO Chassis is okay and implicating the I/O Computer.

Our best test would be to actually have the fault state and repeat this check of the BIO Chassis outputs.

Meanwhile, I hear Richard instructed EdM to power things down and reseat the I/O Computer cards but I haven't heard that directly or seen a log.
