*		   BUFFALO
* "Bit User's Fast Friendly Aid to Logical Operation"
*
* Rev 2.0 - 4/23/85 - added disassembler.
*		    - variables now PTRn and TMPn.
* Rev 2.1 - 4/29/85 - added byte erase to chgbyt routine.
* Rev 2.2 - 5/16/85 - added hooks for evb board - acia
*		      drivers, init and host routines.
*	    7/8/85  - fixed dump wraparound problem.
*	    7/10/85 - added evm board commands.
*		    - added fill instruction.
*	    7/18/85 - added jump to EEPROM.
* Rev 2.3 - 8/22/85 - call targco to disconnect sci from host
*		      in reset routine for evb board.
*	    10/3/85 - modified load for download through terminal.
* Rev 2.4 - 7/1/86  - Changed DFLOP address to fix conflicts with
*		      EEPROM.  (was at A000)
* Rev 2.5 - 9/8/86  - Modified to provide additional protection from
*		      program run-away on power down.  Also fixed bugs
*		      in MM and MOVE.  Changed to 1 stop bit from 2.
* Rev 2.6 - 9/25/86 - Modified boot routine for variable length download
*		      for use with 'HC11E8.
* Rev 3.0   1/15/87 - EEPROM programming routines consolidated into WRITE.
*		      Fill, Assem, and breakpoints will now do EEPROM.
*		    - Added compare a to $0D to WSKIP routine.
*	    2/11/87 - Set up load to detect receiver error.
* Rev 3.2   7/7/87  - Add disassembly to trace.
*		    - Add entries to jump table.
*	    9/20/87 - Rewrote trace to use XIRQ, added STOPAT Command
*	    11/24/87- Write block protect reg for 'E9 version
*		    - Modified variable length download for use
*			with 'E9 bootloader (XBOOT command)
* Rev 3.3   3/17/88 - Set I bit to block interrupts on Warm Start and
*			return from CALL command.
*		    - Added EEMOD Command.
*		    - Rearranged source so that HELP command overlaps
*			EEPROM in test mode.
*	    3/24/88 - Added '+', '-', '=', '.' to MEM and ASM commands.
*		    - Added check for 16 byte boundary to MEM
*			space sub-command.
*		    - LOAD command now puts dummy (~) command into
*			inbuff so that any stray cr's won`t hang.
* Rev 3.4   8/15/88 - Changed WRITE subroutine so that config register
*			gets byte erased before programmed.  The original
*			value of config is used for EEBYTE so that config
*			RAM value doesn't get changed in test mode.
*	    8/17/88 - Fixed MOVE command so that it doesn't hang when move
*			is done to a ROM location.
*		    - Added OFFSET command for download offset capability.
