 Program:    TAPDSK


  TAPDSK  will backup hard disk partitions (Drives A thru P) as selected
	  from the opening screen menu selection.

	  TAPDSK will read the BIOS drive table to determine which par-
	  titions are available and display then on the menu.

	  Upon	selection of a drive partition, the operator may select
	  which system tracks to back-up.

	  TAPDSK will restore each partition from whence it came, A to A
	  B to B, etc.

	  Notice that TAPDSK is an image copying program, it reads from
	  the hard disk sector by sector.  Any bad sectors are copied as
	  well and an error message displayed and copying continued.  As
	  a result when restoring the partition any bad sectors recorded
	  will be restored to the hard disk even if there isn't any.

 Configuring TAPDSK

  TAPDSK  comes configured for an AMPRO Computer only.	It makes calls
	  to the BIOS and uses SCSI code generic to the Ampro hardware.
	  There are equates in the beginning of the source code to alter
	  the following:



	    CLOCK   EQU     YES       ; If CTC hardware clock available
	    TELVID  EQU     NO	      ; Televideo terminal
	    H19     EQU     NO	      ; Heath H/Z19 terminal
	    LFEEDS  EQU     YES       ; Clear screen with line feeds
	    TOGGLE  EQU     YES       ; Rewind upon completion

 CLOCK equate

	  If set NO, an 'F' option on the opening screen menu will be
	  visable to allow entry of date and time if no clock is avail-
	  able.  The time prompt also allows a 78 character entry.

 TELVID equate

	  If set YES, LFEEDS must be set NO
		      H19    must be set NO also
	     will use the Televideo escape * to clear its screen.

 H19 equate

	  if set YES, LFEEDS must be set NO
		      TELVID must be set NO also
	     will use the H/Z19 escape 'E' to clear its screen, also
	     an opening message will be displayed, and will time out
	     to the opening screen menu.
 TOGGLE equate

	 if set YES, will allow usefull information to be returned
	    from the TEAC tape unit for a SASI programmer.   Reading
	    the manual of the TEAC and understanding the SCSI system
	    will provide the information to understand this option.
	    The option is really a carryover from the development and
	    debugging of the program TAPDSK.


 NOTE:

	  TAPDSK may be assembled with M80 and linked with L80.  Other
	  assemblers may be used such as ZAS and ZLINK or SLR's Z80ASM
	  (no linker needed, it makes an object code .COM file direct.)
