	09-Jul-1990	RAC	Seperated from TWQIC.C
	06-Mar-1991	MDB	Added polled non-interrupt support for
				Alliance parallel host adapter. This is done
				via the -INT=255 option.

	24-Sep-1991	RAC	Added support for 3.01 header files and
				Borland C++ compiler. Changed version number
				to 3.01.00.

	26-Mar-1992	MDB	Added code to confirm interrupt generation by
				the QIC-02 controller we are currently

	Version 4.00.04 ------>	Release with 4.00.00

	25-Nov-1992	RAC	Reset the CurrentControl mask during the 
				reset of the drive. This allows the TWSTQ
				driver to issue the CMD_IOPB_RESET function
				to get around a general problem with the
				Alliance DAT.

	Version 4.00.05	------>	Alpha 25-Nov-1992

	07-Dec-1992	RAC	Switched PIO output and input to use the
				dispatching versions of the WaitForEvent
				functions. This allows the Archive QFA
				which uses PIO output to set the block number
				to dispatch while the device is seeking...

	Version 4.00.06 ------> Alpha 07-Dec-1992

	10-Dec-1992	RAC	Removed state # 7 in PIO_Output. Assume that
				the drive will deassert ready when command
				processing is output.

	10-Dec-1992	RAC	Reduce time delays values for going on/offline
				Also, reduce time delays during the reset.
				They were just tooooooo long!
