Tried to put up 3.15/10 AMPEX CORE 1
stopped getting data. All words seem to
get to AMPEX MB as 0. Cycles are
completed and the MA is recieved correctly.

CP MA bit 22 lamp is intermittent.

Problem with AMPEX was 2 timing
pulses in read timing delay line. Cause was
opening of terminating resistor in delay
line. Jumper to end of delay line
had never been soldered to delay line.
Added solder to joint. Bug fixed. Ran
3 copies of 40K BLTST in disk system for 15 min.
