We did have an enjoyable dinner last night though ;-) This morning we had some problems getting the DECtape operational - due I believe, to the cold temp. Once running the DECtape worked all day without a glitch. We left the machine running tonight so we won't have that problem tomorrow. In view of the DECtape not working at first we tackled the paper tapes first. After some problems we decided that the easiest and surest way was to PIP the tapes to a DECtape, then dump the tape. By that time the DECtape were running. On the FTP site, the file 'ptapes.dta' is a SIMH image of the DECtape containing the following files: LPAINK SRC HAL70 DEF HAL70B SRC HAL70C SRC HAL70E SRC ECCE SRC ECCEB SRC The other files on the image are failed attempts. The file 'tapelog' shows that for the three HAL70 we got parity errors at different points. It should not be too difficult to splice together a good version. Similarily for ECCE.SRC and ECCEB.SRC. We then tackled teh DECtapes. We tried PIP directory listings of each tape which we numbered 01 to 29. Those listings are in the file 'tdirs' Chris immediately noted the importance of tape22 and we dumpped that one and tapes 01 and 02, the corresponding files on the site are 'tape22.dta', tape01.dta' and 'tape02.dta' Tapes numbers 1 through 4 are the four you were particularly interested in. Of these only 1 and 2 show coherent directories and we took images of them. Many tapes show no coherent directoy listing, this could be because they are not PDP-9 tapes, or that they are binary tapes. Tomorrow we will see if we can find a tape that could be an IMP bootable tape. Check the tdir file and if there are any of the tapes which you particularly want to see dumps of let me know and we can do those first. Otherwise we plan on copying all the tapes to blank DECtapes so that I can dump them later on after Chris leaves (Copying a tape is much quicker than dumping them). I think we can say today was successful, let me know what you can get frorm the tapes we have already dumped. Regards, -- Hans
