# PROGRAM NAME -- KEYBOARD AND DISPLAY PROGRAM
# MOD NO -- 4		DATE -- 27 APRIL 1967		ASSEMBLY -- PINDANCE REV 18
# MOD BY -- FILENE
# LOG SECTION -- PINBALL GAME BUTTONS AND LIGHTS
#
# FUNCTIONAL DESCRIPTION
#
# THE KEYBOARD AND DISPLAY SYSTEM PROGRAM OPERATES UNDER EXECUTIVE
# CONTROL AND PROCESSES INFORMATION EXCHANGED BETWEEN THE AGC AND THE
# COMPUTER OPERATOR.  THE INPUTS TO THE PROGRAM ARE FROM THE KEYBOARD,
# FROM INTERNAL PROGRAM, AND FROM THE UPLINK.
#
# THE LANGUAGE OF COMMUNICATION WITH THE PROGRAM IS A PAIR OF WORDS
# KNOWN AS VERB AND NOUN.  EACH OF THESE IS REPRESENTED BY A 2 CHARACTER
# DECIMAL NUMBER.  THE VERB CODE INDICATES WHAT ACTION IS TO BE TAKEN, THE
# NOUN CODE INDICATES TO WHAT THIS ACTION IS APPLIED.  NOUNS USUALLY
# REFER TO A GROUP OF ERASABLE REGISTERS.
#
# VERBS ARE GROUPED INTO DISPLAYS, LOADS, MONITORS (DISPLAYS THAT ARE
# UPDATED ONCE PER SECOND), SPECIAL FUNCTIONS, AND EXTENDED VERBS (THESE
# ARE OUTSIDE OF THE DOMAIN OF PINBALL AND CAN BE FOUND UNDER LOG SECTION
# 'EXTENDED VERBS').
#
# A LIST OF VERBS AND NOUNS IS GIVEN IN LOG SECTION 'ASSEMBLY AND 
# OPERATION INFORMATION'.
#
## Ram&oacute;n Alonso, one of the original AGC developers, provides a 
## little more insight:  Apparently, nobody had yet arrived at any kind 
## of software requirements for the AGC's user interface when the desire
## arose within the Instrumentation Laboratory to set up a demo 
## guidance-computer unit with which to impress visitors to the lab.  
## Of course, this demo would have to <i>do</i> something, if it was going to be 
## at all impressive, and to do something it would need some software. In 
## short order, some of the coders threw together a demo program, 
## inventing and using the verb/noun user-interface concept (in the 
## whimsical fashion seen in much of this code), but without any idea 
## that the verb/noun concept would somehow survive into the flight 
## software.  As time passed, and more and more people became familiar 
## with the demo, nobody got around to inventing an improvement for the 
## user interface, so the coders simply built it into the flight software 
## without any specific requirements to do so.<br>
## <br>
## However, that does not mean that the verb/noun interface was universally 
## beloved.  Ram&oacute;n says that <i>many</i> objections were received from 
## naysayers, such as "it's not scientific", "it's not dignified", or 
## even "astronauts won't understand it".  Even though the coders of 
## the demo hadn't seriously intended the verb/noun interface to be used 
## in any permanent way, it became a kind of devilish game to counter 
## these objections with (perhaps) sophistic arguments as to why the 
## interface was really a good one.  In the end, the coders won.  I don't 
## know whether they were elated or dismayed by this victory.<br>
## <br>
## The astronauts, of course, <i>could</i> understand the interface, 
## but they did not like it.  Most of them really wanted an interface much 
## more like that they had used in aircraft:  i.e., lots of dials and 
## switches.  Dave Scott is the the only astronaut I'm aware of who had 
## kind words for it (or for the AGC in general), though we are told that 
## Jim McDivitt wasn't necessary completely hostile to it.<br>

#
# CALLING SEQUENCES --
#
# KEYBOARD:
# EACH DEPRESSION OF A KEYBOARD BUTTON ACTIVATES AN INTERRUPT KEYRUPT1
# AND PLACES THE 5 BIT KEY CODE INTO CHANNEL 15.  KEYRUPT1 PLACES THE KEY
# CODE INTO MPAC, ENTERS AN EXECUTIVE REQUEST FOR THE KEYBOARD AND DISPLAY
# PROGRAM (AT 'CHARIN'), AND EXECUTES A RESUME.
#
# UPLINK:
# EACH WORD RECEIVED BY THE UPLINK ACTIVATES INTERRUPT UPRUPT, WHICH
# PLACES THE 5 BIT KEY CODE INTO MPAC, ENTERS AN EXECUTIVE REQUEST FOR THE
# KEYBOARD AND DISPLAY PROGRAM (AT 'CHARIN') AND EXECUTES A RESUME.
#
# INTERNAL PROGRAMS:
# INTERNAL PROGRAMS CALL PINBALL AT `NVSUB' WITH THE DESIRED VERB/NOUN
# CODE IN A (LOW 7 BITS FOR NOUN, NEXT 7 BITS FOR VERB).  DETAILS
# DESCRIBED ON REMARKS CARDS JUST BEFORE 'NVSUB' AND 'NVSBWAIT' (SEE
# SYMBOL TABLE FOR PAGE NUMBERS).
#
# NORMAL EXIT MODES --
#
#	IF PINBALL WAS CALLED BY EXTERNAL ACTION, THERE ARE FOUR EXITS:
#		1)	ALL BUT (2), (3), AND (4) EXIT DIRECTLY TO ENDOFJOB.
#		2)	EXTENDED VERBS GO TO THE EXTENDED VERB FAN AS PART OF THE
# Page 391
#			PINBALL EXECUTIVE JOB WITH PRIORITY 30000.  IT IS THE 
#			RESPONSIBILITY OF THE EXTEDED VERB CALLED TO EVENTUALLY
#			CHANGE PRIORITY (IF NECESSARY) AND DO AN ENDOFJOB.
#			ALSO PINBALL IS A NOVAC JOB.  EBANK SET FOR COMMON.
#		3)	VERB 37.  CHANGE OF PROGRAM (MAJOR MODE) CALLS 'V37' IN THE
#			SERVICE ROUTINES AS PART OF THE PINBALL EXEC JOB WITH PRIO
#			30000.  THE NEW PROGRAM CODE (MAJOR MODE) IS LEFT IN A.
#		4)	KEY RELEASE BUTTON CALLS 'PINBRNCH' IN THE DISPLAY INTERFACE
#			ROUTINES AS PART OF THE PINBALL EXEC JOB WITH PRIO 30000 IF 
#			THE KEY RELEASE LIGHT IS OFF AND 'CADRSTOR' IS NOT +0.
#
# IF PINBALL WAS CALLED BY INTERNAL PROGRAMS, EXIT FROM PINBALL IS BACK
# TO CALLING ROUTINE.  DETAILS DESCRIBED IN REMARKS CARDS JUST BEFORE
# 'NVSUB' AND 'NVSBWAIT' (SEE SYMBOL TABLE FOR PAGE NUMBERS).
#
# ALARM OR ABORT EXIT MODES --
#
# 	EXTERNAL INITIATION:
#	IF SOME IMPROPER SEQUENCE OF KEY CODES IS DETECTED, THE OPERATOR
#	ERROR LIGHT IS TURNED ON AND EXIT IS TO 'ENDOFJOB'.
#
#	INTERNAL PROGRAM INITIATION:
#	IF AN ILLEGAL V/N COMBINATION IS ATTEMPTED, AN ABORT IS CAUSED
#	(WITH OCTAL 01501).
#	IF A SECOND ATTEMPT IS MADE TO GO TO SLEEP IN PINBALL, AN ABORT IS
#	CAUSED (WITH OCTAL 01206). THERE ARE TWO WAYS TO GO TO SLEEP IN PINBALL:
#		1) ENDIDLE OR DATAWAIT.
#		2) NVSBWAIT, PRENVBSY, OR NVSUBUSY.
#
# CONDITIONS LEADING TO THE ABOVE ARE DESCRIBED IN FORTHCOMING MIT/IL
# E-REPORT DESCRIBING KEYBOARD AND DISPLAY OPERATION FOR 278.
#
# OUTPUT --
#
# INFORMATION TO BE SENT TO THE DISPLAY PANEL IS LEFT IN THE 'DSPTAB'
# BUFFERS REGISTERS (UNDER EXEC CONTROL). 'DSPOUT' (A PART OF T4RUPT)
# HANDLES THE PLACING OF THE 'DSPTAB' INFORMATION INTO OUTPUT CHANNEL 10
# IN INTERRUPT.
#
# ERASABLE INITIALIZATION --
#
# FRESH START AND RESTART INITIALIZE THE NECESSARY E REGISTERS FOR
# PINBALL IN 'STARTSUB'.  REGISTERS ARE:  DSPTAB BUFFER, CADRSTOR,
# REQRET, CLPASS, DSPLOCK, MONSAVE, MONSAVE1, VERBREG, NOUNREG, DSPLIST,
# DSPCOUNT, NOUT.
#
# A COMPLETE LIST OF ALL THE ERASABLES (BOTH RESERVED AND TEMPORARIES) FOR
# Page 392
# PINBALL IS GIVEN BELOW.
#
# THE FOLLOWING ARE OF GENERAL INTEREST --
#
# REMARKS CARDS PRECEDE THE REFERENCED SYMBOL DEFINITION.  SEE SYMBOL
# TABLE TO FIND APPROPRIATE PACE NUMBERS.
#
#	NVSUB		CALLING POINT FOR INTERNAL USE OF PINBALL.
#			OF RELATED INTEREST	NVSBWAIT
#						NVSUBUSY

#			AWAITING OPERATORS RESPONSE.
#
#	DSPMM		ROUTINE BY WHICH AN INTERNAL PROGRAM MAY DISPLAY A DECIMAL
#			PROGRAM CODE (MAJOR MODE) IN THE PROGRAM (MAJOR MODE) LIGHTS.
#			(DSPMM DOES NOT DISPLAY DIRECTLY BUT ENTERS EXEC REQUEST
#			FOR DSPMMJB WITH PRIO 30000 AND RETURNS TO CALLER.)
#
#	BLANKSUB	ROUTINE BY WHICH AN INTERNAL PROGRAM MAY BLANK ANY
#			COMBINATION OF THE DISPLAY REGISTERS R1, R2, R3.
#
#	JAMTERM		ROUTINE BY WHICH AN INTERNAL PROGRAM MAY PERFORM THE
#	JAMPROC		TERMINATE (V 34) OR PROCEED (V 33) FUNCTION.
#
#	MONITOR		VERBS FOR PERIODIC (1 PER SEC) DISPLAY.
#
#	PLEASE PERFORM, PLEASE MARK SITUATIONS
#		REMARKS DESCRIBING HOW AN INTERNAL ROUTINE SHOULD HANDLE
#		THESE SITUATIONS CAN BE FOUND JUST BEFORE 'NVSUB' (SEE
#		SYMBOL TABLE FOR PAGE NUMBER).
#
#	THE NOUN TABLE FORMAT IS DESCRIBED ON A PAGE OF REMARKS CARDS JUST
#	BEFORE 'DSPABC' (SEE SYMBOL TABLE FOR PAGE NUMBER).
#
#	THE NOUN TABLES THEMSELVES ARE FOUND IN LOG SECTION 'PINBALL NOUN
#	TABLES'.

# PROGRAM USING THE KEYBOARD + DISPLAY PROGRAM.
#
# NVSUBUSY ABORTS (WITH CODE 01206) IF A SECOND JOB ATTEMPTS TO GO TO

# WHEN
