- There are several possibilities for what format those tapes are in. See if
- there's any marking on them that suggests one; if not, just try the
- various possibilities.
-
- 1. (most likely) "DOS format" tape. This is the classical RSTS magtape
- format, inherited from DOS-11. VMS can read those using the EXCHANGE
- program. Try:
- EXCHANGE DIR mmxx:/VOL=DOS
- (where mmxx: is the tape device name. The tape must be mounted/FOREIGN
- before you do this.)
-
- 2. "ANSI" format tape. This is the newer standard magtape format, used
- normally in VMS and one of the choices in later versions of RSTS (including
- version 8). Try MOUNT (without the /FOREIGN, but with /OVER=ID) on the
- tape. If that works, it was ANSI, and you can DIR or COPY it using
- standard DCL operations.
-
- 3. "Old BACKUP" format. This should not be confused with "new BACKUP"
- format -- which arrived with RSTS V9, and is compatible with VMS Backup.
- The Old BACKUP format is specific to the old RSTS backup program. I don't
- know of any VMS programs that can read it. (It's possible you could
- port the RSTS Backup program, which is written in BASIC, to VMS and
- run it there, but that would be a hassle at best...) The only obvious
- way to read such a tape is:
- a. On a V9 or later RSTS system, read it with RESTOR, then copy
- the resulting files to tape with (new) BACKUP for your VMS system.
- b. On a V8.x system, read the tape with BACKUP (old), then copy
- the resulting files to tape with PIP either in DOS or ANSI
- mode, and use steps 1 or 2 above to read the result.
