^^BOOT11\\ IS A BOOTSTRAP PROGRAM DESIGNED TO LOAD OR DUMP PROGRAMS
FROM THE ^P^D^P-10 INTO A ^P^D^P-11 THRU THE ^P^D^P-10, ^P^D^P-11
^DATA ^LINK (^D^L10).  ^THE TWO MAIN FUNCTIONS OF ^^BOOT11\\ ARE:

.BLANK 1
.LEFT MARGIN 0
^^BOOT11\\ RUNS IN ^^USER\\ MODE UNDER A ^^DEC\\SYSTEM-10
TIMESHARING SYSTEM.  ^IT REQUIRES A MINIMUM OF 2^K OF MEMORY BUT EXPANDS
FOR ^I^O BUFFERS AND FOR THE COMMON MEMORY AREA THE ^D^L10 PROVIDES
TO THE ^P^D^P-11.  ^^BOOT11\\ "LOCKS" ITSELF IN ^P^D^P-10
MEMORY AND DOES ^I^O INSTRUCTIONS DIRECT TO THE ^D^L10 HARDWARE.  ^FOR
THIS TO WORK, THE ^^BOOT11\\ JOB MUST HAVE PRIVILEGES FOR THE
^^TRPSET\\ AND ^^LOCK\\ FUNCTIONS OF THE TIMESHARING SYSTEM.

.INDENT -4
1.##^^MACRO-11\\ (WHICH RUNS ON THE ^^PDP\\-11).  ^THE "^^.ENABL ABS\\"
PSEUDO INSTRUCTION OR THE "/^^EN:ABS\\" SWITCH IN THE COMMAND STRING
PRODUCES THE BINARY OUTPUT IN FORMATTED BINARY FORM.
.BLANK 1
.INDENT -4
2.##^^MACX11\\ (WHICH RUNS ON THE ^^PDP-10\\).  ^THE
".^^ABS\\" PSEUDO INSTRUCTION  GIVES FORMATTED BINARY OUTPUT.  ^THE 
OUTPUT MAY BE DIRECTED TO THE FILE SYSTEM OR TO PAPER TAPE.  ^THE /^I SWITCH
IN THE COMMAND STRING GIVES "UNPACKED" FORMATTED BINARY.
 ^THE ^^MACX11\\ ASSEMBLER IS 
NOT SUPPORTED BY ^DIGITAL NOW; THE ^^MACY11\\ ASSEMBLER IS THE SUPPORTED
^^PDP-11\\ ASSEMBLER RUNNING ON THE ^^PDP-10\\.
.BLANK 1

3.##^^MACY11\\ (WHICH RUNS ON THE ^^PDP\\-10).  ^THE ".^^ENABL ABS\\"
PSEUDO INSTRUCTION, THE ".^^ABS\\" PSEUDO INSTRUCTION (WHICH IS NOT
PREFERRED), AND THE "/^^EN:ABS\\" SWITCH IN THE COMMAND STRING MAY BE
USED TO GIVE FORMATTED BINARY OUTPUT.  ^THE /^I COMMAND STRING SWITCH
 GIVES "UNPACKED" BINARY OUTPUT AS OPPOSED TO "PACKED" OUTPUT
WHICH IS THE NORMAL DEFAULT.
.BLANK 1
.INDENT -4
4.##^^LINK\\ (RUNNING ON THE ^^PDP-11)\\ LOADS RELOCATABLE
BINARY FILES AND PRODUCES FORMATTED BINARY OUTPUT.
.BLANK 1
.TEST PAGE 6
.INDENT -4
5.##^^LNKX11\\, THE ^^PDP-10\\ EXECUTABLE VERSION OF ^^LINK\\, READS
RELOCATABLE BINARY FILES FOR THE ^^PDP-11\\ AND PRODUCES FORMATTED
BINARY OUTPUT.  ^THE /^I COMMAND STRING SWITCH  GIVES "UNPACKED"
BINARY OUTPUT AS OPPOSED TO "PACKED" OUTPUT WHICH IS THE NORMAL
DEFAULT.
.BLANK 1
.LEFT MARGIN 0
^THERE ARE TWO VERSIONS OF FORMATTED BINARY OUTPUT PRODUCED BY
^^MACX11, MACY11\\ AND ^^LNKX11\\: "PACKED" AND "UNPACKED."  ^THE
"PACKED" VARIATION IS THE NORMAL DEFAULT AND CONSISTS OF FOUR 8-BIT
FRAMES OF FORMATTED BINARY OUTPUT PACKED INTO ONE ^^PDP-10\\ WORD.
(^THE PACKED BINARY FILES ARE VERY CONVENIENTLY STORED IN
THE ^^PDP\\-10 FILE SYSTEM.) ^THE PACKED FORMAT CANNOT BE PUNCHED
ONTO PAPER TAPE DIRECTLY WITH ANY CURRENT PROGRAM OTHER
THAN THE PAPER TAPE SPOOLER. ^^QUEUE\\'S /^^TAPE:ELEVEN\\
SWITCH  TELLS THE SPOOLER TO UNPACK THE PACKED DATA FOR
THE PAPER TAPE PUNCH.

.BLANK 1
^THE "UNPACKED" VARIATION CONSISTS OF ONE 8-BIT FRAME PER ^^PDP-10\\ WORD AND IS
PRODUCED BY USING THE /^I COMMAND STRING SWITCH.  ^THE "UNPACKED"
VARIATION IS THE REQUIRED FORM OF THE BINARY DATA IF IT IS TO BE PUNCHED
ONTO PAPER TAPE EITHER DIRECTLY OR WITH ^^PIP\\.
  (^IF ^^PIP\\ IS USED
^^PIP\\'S /^I SWITCH IS REQUIRED.)
.BLANK 1
^^BOOT11\\  READS EITHER "PACKED" OR "UNPACKED" BINARY DATA.  ^FOR "UNPACKED"
DATA, THE /^^IMAGE\\ SWITCH IS REQUIRED.  ^IF ^^BOOT11\\ READS AN "UNPACKED" FILE
FROM THE FILE SYSTEM WITHOUT THE /^^IMAGE\\ SWITCH, IT DETECTS AN
ERROR AND PRINTS A WARNING MESSAGE, SETS THE /^^IMAGE\\ SWITCH AND
STARTS THE LOADING OPERATION OVER AGAIN.  ^WHEN READING FROM THE PAPER
TAPE READER, ^^BOOT11\\ ALWAYS SETS THE /^^IMAGE\\ SWITCH ITSELF, SO
NO /^^IMAGE\\ SWITCH IS REQUIRED IN THE COMMAND STRING.
.BLANK 1
^^PDP-11\\ PAPER TAPES IN FORMATTED BINARY MAY BE TRANSFERRED TO THE
-10 FILE SYSTEM FOR FUTURE USE. ^THE TAPE SHOULD BE PLACED IN THE
^^PDP-10\\ PAPER TAPE READER WITH THE READ HEAD IN THE BLANK TAPE AREA
AFTER THE PUNCHED TITLE, IF ANY, AND BEFORE THE BINARY DATA.
(^THE START OF THE BINARY DATA IS INDICATED BY A FRAME OF 1 FOLLOWED
BY A FRAME OF 0.) ^^PIP\\, WITH THE /^I SWITCH,  COPIES THE TAPE INTO
THE FILE SYSTEM. ^FILES TRANFERRED THIS WAY ARE IN THE "UNPACKED"
FORMAT. ^USE THE /^^IMAGE\\ SWITCH IN ^^BOOT11\\.
.BLANK 3
4.0##^^GENERAL INTERNAL OPERATION\\
.BLANK 1
^^BOOT11\\ USES THE ^D^L10 HARDWARE TO LOAD, CLEAR, OR DUMP THE ^^PDP\\-11
MEMORY AND TO START OR STOP THE ^^PDP-11\\ PROCESSOR ITSELF.
.BLANK 1
^THE ^^PDP-11/15\\ CONSOLE PANEL (^K^Y11^C) HAS A "REMOTE CONTROL CABLE"
THAT PLUGS INTO THE ^D^L10. ^THIS CABLE ENABLES THE ^D^L10 TO TOGGLE THE
^^PDP-11\\ ^^HALT\\ AND ^^START\\ SWITCHES REMOTELY, TO EXAMINE THE
STATE OF ^^PDP-11\\ POWER, AND TO DETERMINE IF THE ^^PDP\\-11 IS RUNNING
OR IS STOPPED. ^WHEN THE ^D^L10 STARTS THE ^^PDP\\-11, THE ^D^L10 SENDS
THE STARTING ADDRESS TO THE ^^PDP\\-11 OVER THE ^UNIBUS. ^THE STARTING
ADDRESS (100002) IS IN AN AREA OF -11 MEMORY TO WHICH THE ^D^L10 RESPONDS
AND SUPPLIES DATA FROM ^^PDP\\-10 MEMORY CORES. ^IN EFFECT, A ^^PDP\\-11
PROGRAM IS STARTED WHICH EXECUTES OUT OF ^^PDP\\-10 MEMORY. ^THIS ^^PDP\\-11
PROGRAM IS PART OF ^^BOOT11\\ AND HAS THE MAJOR FUNCTION OF TRANSFERRING DATA FROM THE -10 TO THE -11 FOR LOADING AND CLEARING OPERATIONS,
OR FROM THE -11 TO THE -10 FOR THE DUMPING OPERATION. ^^BOOT11\\ EITHER
SUPPLIES DATA TO THE -11 FROM THE FORMATTED BINARY INPUT FILE, OR TAKES
THE ^^PDP-11\\ CORE IMAGE AND WRITES AN -11 DUMP FILE ON SOME -10 DEVICE.
