You are right.  The VS3100 doesn't have MFM either.  That type connector was 
used for a lot of things.  Most likely SCSI on the MV3100 and VS3100.  I 
think the 8-port serial card on the  MV3100 used a centronics type connector 
but may have also used one of those.  If you have a male and a female it may 
be the qbus extention or TSV05 cab kit.  Also printer interfaces used that 
connector.  Only the old MV-I, MV-II, MV2000, etc used it for MFM or tape 
although I suppose any q-bus vax could have an old MFM or tape controller or 
any of the above on it.
