DLU1 is a routine that allows one to backup RK05 disks and RL01 disks onto mag tape. This is a pre-release version. We have also included a handler that will allow you to pull individual files from the DLU1 tapes. The handler makes the DLU1 tapes look like an RT-11 volume. Try a DIR ROn: to get a directory where n is the mag tape unit number.
