Here is an ODS-2 utility which is an
interactive tool to mount a disk, to navigate in the directory
structure and to copy from the disk. Unfortunately the copy is - more
or less - text mode.
Here is an ODS-2 reader which is also interactive but only accepts one command. It's not possible to navigate in the directory structure, the next command again starts at the top, the master file directory. To copy from the disk the full vms path needs to be specified. There is a binary copy. Unfortunately the copy is always into the current directory and the filename is always as on the ODS-2 disk. So an additional rename is required to make a lowercase filename out of the UPPERCASE filename from ODS-2.
Any question, suggestion, bug report? Please send mail to ods2 at vms2linux.de.
