C INTRODUCTION:
C -------------
C THE ASSEMBLY OF LARGE PROGRAMS FOR SMALL MACHINES SUCH AS
C THE PDP8 IS APT TO BE LABORIOUS, TIME CONSUMING AND ALMOST
C IMPOSSIBLE IS DONE ON THE SMALL MACHINE ITSELF. IN ADDITION,
C THE ABILITY FOR MANY USERS TO ASSEMBLE PDP8 PROGRAMS ON A PDP10
C COMPUTER USING PAL10 OR PAL12 LIGHTENS THE LOAD OF SOFTWARE
C DEVELOPMENT ON THE SMALLER MACHINE. TALK8F IS A PDP10
C UTILITY PROGRAM WHICH TRANSFORMS THE OUTPUT OF ASSEMBLERS
C SUCH AS PAL10 OR PAL12 INTO A FORM AMENABLE TO DATAPHONE
C COMMUNICATION.
C
C
C
C HARDWARE REQUIRED:
C --------------------
C PDP10 WITH DATAPHONE OR HARDWARE INTERFACE
C TO A PDP8 WITH A PT08 SERIAL/PARALLEL INTERFACE.
C
C
C
C DESCRIPTION:
C -----------
C THIS PROGRAM READS A PAL10 ".BIN" OUTPUT FILE FROM THE DISK
C AND CONVERTS IT TO A FORM OF ASCII CHARACTERS CODE.
C THIS CODE CAN BE SENT OVER THE TELEPHONE LINES AND
C INTERPRETED BY THE PDP8 "TALK10" PROGRAM RUNNING ON THE
C PDP-8.(A PUNCHED PAPER TAPE MAY BE READ INTO THE PDP8 THROUGH
C "OCTMON", A PDP8 OCTAL DEBUGGER PROGRAM, DECUS 8-298, WHICH
C ACCEPTS THIS SPECIAL CODE FORMAT.)
C THE PAL10 BINARY OUTPUT FILE MUST BE ON THE USER'S DSK AREA.
C A ".DAT" FILE, NAMED BY THE USER, WILL BE GENERATED AND WRITTEN
C IN THE USER'S DISK AREA . HE MAY THEN PIP IT TO HIS TELETYPE (TTY).
C (I.E. TO HIS BUFFERED PDP8 TTY THROUGH THE PDP8 TALK10 PROGRAM WHICH
C IS INTERFACED TO THE PDP10 THROUGH THE PT08.).
C THE BEGINNING AND END OF THE ".DAT" FILE CONTAIN STRINGS OF A'S
C WHICH ARE USED TO ENTER AND LEAVE THE TALK10 "OCTLDR" MODE.
C IF THE USER IS TALKING TO THE PDP10 VIA TALK10, SENDING THE ".DAT"
C FILE WILL LOAD IT INTO THE PDP8 MEMORY.
C
C
C
C
C
C
C CODING OF THE PAL10 BINARY OUTPUT FILE:
C ---------------------------------------
C THE "FIELD" CODE IS CONVERTED TO A 4 DIGIT NUMBER FOLLOWED BY "F".
C THE "MEMORY LOCATION" CODE IS CONVERTED TO A 4 DIGIT OCTAL NUMBER
C FOLLOWED BY A "Z". THIS IS THE LOCATION WHERE THE NEXT DATUM WILL
C BE PUT. THE "DATA" CODE IS CONVERTED TO A 4 DIGIT OCTAL NUMBER
C FOLLOWED BY A CARRIAGE RETURN. THE LEADER TRAILER CODE IS USED TO
C SIGNAL TALK8F THAT THE BEGINNING AND END OF THE FILE IS REACHED.
C
C
C
C
C
C COMPILING THE SOURCES:
C -------------------------
C NOTE: (1) TO COMPILE TALK8F, COMPILE TALK8F.F4 AND READPL.MAC .
C (2) LOAD TALK8F.REL AND READPL.MAC TOGETHER.
C (3) DO A SAVE DSK:TALK8F.SAV TO GET THE ".SAV" FILE .
C
C
C
C
C
C EXAMPLE OF TALK8F/TALK10 OPERATION
C ------------------------------------
C EXAMPLE: (IT IS ASSUMED THAT THE USER IS TALKING TO THE PDP10
C FROM THE PDP8 TTY <==> (PDP8 PROGRAM "TALK10") <==> PT08 <==> PDP10.
C EXAMPLE:
C --------
C (1) ASSEMBLE THE PDP8 SOURCE FILE PDP8.SRC USING PAL10
C .R PAL10
C *PDP8.BIN,PDP8.LST_PDP8.SRC
C *^C
C .
C (2) NOW CONVERT THE PDP8.BIN FILE TO THE ASCII CODE FILE.
C .RUN DSK:TALK8F.SAV
C INPUT FILE:PDP8
C EXTENSION?:BIN
C OUTPUT FILE:PDP8
C
C YOU MAY NOW PIP PDP8.DAT FROM YOUR DISK AREA.
C EXIT
C .
C
C (3) NOW TRANSMIT THE ASCII "PDP8.DAT" FILE TO THE PDP8 TO BE
C LOADED INTO THE PDP8 MEMORY BY THE TALK10 PROGRAM.
C .R PIP
C *TTY:_DSK:PDP8.DAT
C *
C (4) THE ".DAT" FILE CONTAINS A STRING OF A'S IN THE BEGINNING
C AND END OF THE FILE. THESE ARE USED TO TURN ON AND OFF THE
C PDP8'S TALK10 PROGRAM LOADER SUBPROGRAM CALLED "OCTLDR".
C AFTER THE REST OF THE A'S HAVE BEEN TYPED OUT, THE PROGRAM
C IS NOW LOADED INTO THE PDP8 MEMORY AND TALK10 IS
C IN BUFFERED TELETYPE MODE AGAIN.
C NOTE: A PROGRAM MAY BE LOADED INTO ANY PDP8 FIELD AS TALK8F
C WILL DO FIELD CONVERSIONS FOR ANY FIELD AND TALK10 WILL LOAD
C INTO ANY FIELD. TALK10 DOES NOT PREVENT DESTROYING ITSELF
C BY LOADING INTO ITS OWN CORE IMAGE.
