The only thing that is in any way familiar about this is the Cipher name. Cipher Data Products was a supplier of 9-track tape drives for most of the time during which 9-track drives were relevant. For example, I've got an S-100 board set and a controller formatter which comes from Cipher. The board set I have seems to be a Pertec-type interface adapter, though, i.e. it uses the same pair of 50-conductor cables. Is that what you have on this tape drive? Is it a 9-track type?
