   Correct. somewhere I do have the installation manual for the 9877 and it does clearly show a 98032 interface. I don't remember the option number of the interface but it's probably 77 or 077. That seems to be typical of how HP assigns option numbers on the 98032.

   No, that's another thing that needs to be found. NASA does have the interface on theirs but I couldn't get them to give me any info about the jumpers or anything other than the interface PN.

That's something else I've not managed to find (98032s I have,

   Same here.

    It should be able to. AFIK the 9877 will duplicate all 9825 tapes. Accroding to an x-HP engineer that was one of the 9825 developers, the 9877 was designed specificly for HP factory use to mass duplicate 9825 tapes so I would think it would duplicate everything. I don't remember if the 9825 has a file protect command or not but if so then it might not duplicate protected files.

   Let's just hope that this tape is good. I need to find somebody that has a 9825 with REAL good tape drive and that can read this tape and make some copies. I'm wondering if there might be any way to read and duplicate the tape that would be gentler on it. Any ideas?
