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 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. 91 91
