Subject:  PDP-11 tapes


I have a tape that was written on a PDP-11 running RSTS with PIP. I
have tried (unsuccessfully) several times to take it off on our VAX
(VMS 4.2) with the RSX utilities. Even Exchange was only able to get one
and a half of the six files off the tape. (The half is one that it mangled.)
Every time that I try with Exchange(and FLX, PIP gives me tape-not-ready
even though it is) it will give me an error something like 'error in input
stream format', and FLX says 'bad ASCII record format'. I know that these
files were write verified. Can anyone offer any suggestions?

Five of the files are pictures of the type that reprint the same line
three times printer. (Mona Lisa, Spock, Moon, you know what I mean.)

The sixth is a text file. It came off perfect. Any new ideas would be
greatly appreciated. Thanks.

------------------------------

Transferring files from RSTS/E to VMS is complicated, because RSTS/E
is a stream data system, but also supports RMS-11.

Initialize your tape on the RSTS/E system using an ANSI header, not DOS:
          $ INIT/FORM=ANSI MT: <label>

Put RSTS/E stream text files to tape using the RSTS/E command
          $ PIP MT:/RMS=<RSTS/E file>

Put RSTS/E RMS files to tape using the RSTS/E command
          $ PIP MT:=<RSTS/E file>

I think you would put block I/O files on tape using
          $ PIP MT:/BL=<RSTS/E file>

If you do this, you can read the files from the VAX without using EXCHANGE,
i.e. MOUNT the tape and use COPY.

Now it is time for you to ask yourself what format those neat pictures of
yours are, and copy them appropriately.  Let me know if you have trouble.
