+*
+*
+* VERSION
+* 1.0 (24.04.2006) - INITIAL VERSION
+*
+*
+*
+* STORAGE REQUIREMENT
+* ONE SEGMENT
+*
+*
+* FEATURES:
+* NO 4/6/6 FORMAT, DIRECT BINARY DATA
+* BLOCK CHECKSUMS
+* LOAD AND GO CAPABLE
+* SUPPORTS ONLY HIGH SPEED PAPER TAPE PUNCH
+*
+*
+* USAGE
+* FIRST LOAD THE OBJECT TAPE INTO ANY SECTOR 'XX000 IN MEMORY.
+* TO PUNCH A SELF LOADING TAPE DO THE FOLLOWING:
+* -PRESS MSTCLR
+* -SET P TO 'XX000
+* -IF LOAD AND GO IS DESIRED, PUT PROGRAM'S START ADDRESS INTO A
+* -PRESS START
+* -ENTER THE FIRST ADDRESS TO BE PUNCHED INTO A
+* -PRESS START
+* -ENTER THE LAST ADDRESS TO BE PUNCHED INTO A
+* -PRESS START, BINAL PUNCHES YOUR SYSTEM TAPE
+*
+* TO MAKE A BINAL SLST TAPE
+* USE 'XX000 THAT AS FIRST LOCATION TO BE PUNCHED.
+* THE LAST LOCATION TO BE PUNCHED IS 'XX577, THE REST OF THE SECTOR IS
+* ALWAYS AND AUTOMATICALLY PUNCHED OUT.
+*
+* LOADING SLST TAPES
+* SIMPLY MOUNT THE GENERATED TAPE ON THE HIGH SPEED PAPER TAPE READER
+* AND LOAD WITH THE STANDARD KEY-IN LOADER.
+* THE CONTENTS OF THE TAPE GO TO WHERE THEY COME FROM. THE THIRD STAGE
+* LOADER GOES TO 'XX600. THIS LOCATION CAN BE ALTERED BY ENTERING AN
+* ADDRESS INTO A BEFORE STARTING THE KEY-IN LOADER.
+* IT IS ALSO POSSIBLE TO ALTER THE THIRD-STAGE LOADER ADDRESS BEFORE
+* PUNCHING BY DEPOSITING ANOTHER ADDRESS INTO 'XX600.
+*
+* SPECIAL MODES OF OPERATION
+* IT IS POSSIBLE TO COLLECT THE OUTPUT OF MULTIPLE RUNS OF BINAL INTO
+* ONE SYSTEM TAPE. THIS IS DONE BY SENSE SWITCH SETTINGS:
+* SSW1 SET - DON'T PUNCH OUT SECOND AND THIRD STAGE LOADERS
+* SSW2 SET - DON'T PUNCH OUT DATA
+* SSW3 SET - DON'T PUNCH OUT END OF TAPE/GO BLOCK
+* SSW4 SET - PUNCH ONLY A GO BLOCK
*
* TAPE FORMAT:
-* THE TAPE CONTAINS DATA BLOCKS.
+* THE TAPE CONTAINS HIGE DATA BLOCKS.
* EVERY BLOCK IS PREPENDED WITH THE BLOCK START CHARACTER
* AND THE BLOCK TYPE BYTE.
* THEN FOLLOWS THE BLOCK DATA IN 16BIT BIG ENDIAN FORMAT.
