    9797Accordingly, we reverse-engineered the circuit diagram based on measurements
    9898on an existing card and rebuilt the card. Now the core memory of our IBM 1130
    99 is working like a charm which is a significant milestone.

     101<b>16.6.2014:</b> Giant leaps: After an intensive cleaning effort with adjustments following,
     102the card reader IBM 1442 is now fully operational and we could successfully
     103run the seven so-called "One-Card-Diagnostic" programs. This demonstrated
     104that the CPU is at least basically operating (since these tests are quite
     105simple in nature they can not detect subtle faults).<br>
     106The next test involved the console printer: A working console printer is necessary to communicate
     107with the machine - unfortunately, this test showed that the printer is still
     108faulty. Currently, we suspect resinified oil as the culprit. Stay tuned...
