    89 <b>7.6.2014:</b> The card 7342, we are looking fore, is only located in systems with memory expansion. These Mainframes are much rarer than the "small" IBM 1130 without the left-side table addition. Therefore, both the desired card as well as its circuit diagram are nowhere to be preserved.<br>
    90 So we have worked out the circuit diagram of the wiring gradients and measurements and rebuilt the card. Now the core memory is running properly. This is a significant advance.
     89<b>7.6.2014:</b> The card 7432 we are looking for is only used in systems with a memory
     90expansion. These mainframes are much rarer than the smaller IBM 1130 systems
     91without the additional left enclosure. Therefore both, the card missing in
     92out machine as well as its schematics have apparently not been preserved.
     93Accordingly, we reverse-engineered the circuit diagram based on measurements
     94on an existing card and rebuilt the card. Now the core memory of our IBM 1130
     95is working like a charm which is a significant milestone.
