Aucbvax.4255 fa.unix-wizards utzoo!decvax!ucbvax!unix-wizards Mon Oct 5 23:17:07 1981 TOPS-10 Interchange Backup Tapes >From ESVAX.clemc@Berkeley Mon Oct 5 23:14:28 1981 Mike Accetta at CMU wrote a program called Backup10 to read PDP-10 backup tapes in interchange mode. The DUMPER program supposedly uses BACKUP format, BUT it writes one or two extra records out (which I have never found out what they are, but no real worry they are 20 dependant and should be ignored). I have used the program successfully to read DUMPER tapes with a mild kludge (e.g. running BACKUP10 through adb, wait for it to die and re-running with a breakpoint and fix the problem). You are welcome to the code, if anyone out there knows what that extra junk is, I'll be happy to fix backup10 to ignore thoses records (like the TEN does). By they way, I have never had any problem getting DUMPER to read, BACKUP10 or standard PDP-10 backup tapes. When I was using it I used to: run dumper on the 20, go over to a standard ten monitor, read the tape, then re-write it. This is a hack but, my tapes were always portable.
