r712 r1281 101 101 working as a punched card computer.<br> 102 102 The next project will be the restauration of the 2310 disk drive. Unfortunately we have no spare hard sectored removeable disks with eight sectors for this drive. All we have are hard sectored disks with 16 sectors. Accordingly we will try to convert one of these to eight 103 sectors by masking every second index slot. 103 sectors by masking every second index slot.<br><br> 104 104 105 <p><b><em>This section will be gradually continued.</em></b></p> 105 <b>10.07.2016:</b> Finally we found time to repair the 2310 disk drive. After 106 replacing a 16 bit buffer register it works like a charm. We already compiled 107 some FORTRAN programs which ran flawlessly. This completes the restoration of 108 this unique machine which is now fully operational again.<br><br> 106 109 110 <b>29.01.2017:</b> We managed to repair the paper tape readers for the 1130. By now 111 we can load the ASCII picture "SNOOPY" from paper tape and print it. The 112 machine can also punch arbitrary data to tape with by means of a program 113 written in FORTRAN and assembly language. This program occupies 392 punch 114 cards. Now only the plotter needs to be connected to the machine.<br><br> 115 116 </p> 117
