        I extracted a TZ30 from a "storage expansion" box that used to
be connected to a alpha station. The drive is SCSI so that it was
trivial to use it in my PC.

        The load system seems extremly unreliable to me: any small
failure when loading/unloading the tape might easly require
disassemble it.

        I performed a deep dust cleaning by disassembling it. I guess
it is fairly easy to disassemble and re-assemble it.
