* 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.
