   19  *  ftreg.h - QIC-40/80 floppy tape driver header
   20  *  06/03/94 v0.9
   21  *  Changed seek load point to QC_SEEKLP, added reqseg to SegReq structure.
   22  *
   23  *  10/30/93 v0.3
   24  *  More things will end up here.  QC_VENDORID and QC_VERSION now used.
   25  *
   26  *  08/07/93 v0.2 release
   27  *  Things that should've been here in the first place were moved.
   28  *  Tape geometry and segment request types were added.
   29  *
   30  *  06/03/93 v0.1 Alpha release
   31  *  Initial revision.  Many more things should be moved here.
