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