r564 r570 85 85 from the machine! That is the worst case for every restoration project! A 86 86 closer inspection revealed, that a second board, 4628, is also missing from 87 the printer control. We are now <a href="/en/wanted.php">looking desperately for replacement boards</a> or 88 at least the schematics. If you can help, please <a href="/en/contact.php">let us know!</a> 87 the printer control. <br><br> 88 89 <b>7.6.2014:</b> The card 7342 we are looking fore is just 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 91 90 92 </small>
