Tracing back
through the fault detector logic, the Clock Error Detector output
is set. Backing up to the entrance, the 4.1 MHz system clock is
coming in correctly on the two 75107 line receiver differential
input pins (E61 1 and 2) but no clock is coming out of it... no
clock -> no operation -> Fault light on :)
Hope they aren't unobtainium parts!
$.59 for the 75107
