If you look
in DEI or 3M documenatation, the on-tape format is not the same as
used on QIC drives.
Does this mean, that the cartriges used with this drive are
not written in the QIC format?
The original drive is a DEI CMTD-3400

So there is no way at all to copy those tapes with a QIC drive on a PC?
To the best of my knowledge, you will need an identical drive plus
controllers. How those controller interface to a PC, is an unknown. When
looking at the signals, it surely is not SCSI. Alone the fact that the drive
has a 40-way connector, will give problems.
Even QIC drives are not all SCSI compliant. I remember an Archive drive
(5956?, 36 MB?) which had its own controller, and could not be spoken to
with e.g. an Adaptec 1510. I think your only chance is to find an
identical/compatible working system in a museum.
