|
# PROGRAM NAME -- SELF-CHECK LOG SECTION: AGC BLOCK TWO SELF-CHECK

|
|
|
|
# FUNCTIONAL DESCRIPTION
|
|
|
|
|
# PROGRAM HAS TWO MAIN PARTS. THE FIRST IS SELF-CHECK WHICH RUNS AS A ZERO PRIORITY JOB WITH NO CORE SET, AS
|
|
|
|
|
# PART OF THE BACK-UP IDLE LOOP. THE SECOND IS SHOW-BANKSUM WHICH RUNS AS A REGULAR EXECUTIVE JOB WITH ITS OWN
|
|
|
|
|
# STARTING VERB.
|
|
|
|
|
#
|
|
|
|
|
# THE PURPOSE OF SELF-CHECK IS TO CHECK OUT VARIOUS PARTS OF THE COMPUTER AS OUTLINED BELOW IN THE OPTIONS.
|
|
|
|
|
#
|
|
|
|
|
# THE PURPOSE OF SHOW-BANKSUM IS TO DISPLAY THE SUM OF EACH BANK, ONE AT A TIME.
|
|
|
|
|
#
|
|
|
|
|
# IN ALL THERE ARE 7 POSSIBLE OPTIONS IN THIS BLOCK II VERSION OF SELF-CHECK. MORE DETAIL DESCRIPTION MAY BE
|
|
|
|
|
# FOUND IN E-2065 BLOCK II AGC SELF-CHECK AND SHOW BANKSUM BY EDWIN D. SMALLY DECEMBER 1966, AND ADDENDA 2 AND 3.
|
|
|
|
|
#
|
|
|
|
|
# THE DIFFERENT OPTIONS ARE CONTROLLED BY PUTTING DIFFERENT NUMBERS IN THE SMODE REGISTER (NOUN 27). BELOW IS
|
|
|
|
|
# A DESCRIPTION OF WHAT PARTS OF THE COMPUTER THAT ARE CHECKED BY THE OPTIONS, AND THE CORRESPONDING NUMBER, IN
|
|
|

# +-4 ERASABLE MEMORY

|
|
|

# -0 SAME AS +-10 UNTIL AN ERROR IS DETECTED.
|
|
|
|
|
# +0 NO CHECK, PUTS COMPUTER INTO THE BACKUP IDLE LOOP.
|

|
#
|
|
|
|
|
# WARNINGS
|
|
|
|
|
# USE OF E MEMORY RESERVED FOR SELF-CHECK (EVEN IN IDLE LOOP) AS TEMP STORAGE BY OTHER PROGRAMS IS DANGEROUS.
