Source Code
|
These source-code files are part of a reconstructed copy of Comanche 72/3 (AKA Manche72 revision 3),
the final, flown mission release of the Apollo Guidance Computer (AGC) Command Module (CM) software
for Apollo 13.
The starting point was the source code of Comanche 72 (itself previously reconstructed). Comanche 72
source code was then modified by incorporating changes known from contemporary documentation to have
been made between revisions 72 and 72/3. The resulting code assembles to have identical
memory-bank checksums as those specified in NASA drawing 2021153G; this gives reasonably
high confidence that the changes that have been made are correct. In places where
ambiguity exists, this ambiguity is discussed in "## Reconstruction:" comments.
Since no contemporary listings of Comanche 72/3 are available as source material,
all comments and labels are approximate.
They have been taken from other AGC programs where possible, or, in some places, written
from scratch to match what we believe would have been in the original listing.

Comanche 67 and earlier used EBANK= RPASS36 (erasable bank 4) for
R36. It has been changed to EBANK= TIG (erasable bank 7) as part
of PCR 936.1, "Initialize V90 time to TIG", in order to give R36
easier access to TIG.

Reconstruction: The following code, down to the next SETLOC, was
completely rewritten in Comanche 72 as part of PCR 936.1, "Initialize V90
time to TIG". The logic in Comanche 67 and earlier accomplished essentially
the same thing, but it was written in basic instead of interpretive, and did
not write the time into TDEC1.

earlier. It has been deleted for Comanche 72 as part of PCR 936.1,
"Initialize V90 time to TIG", because the storing into TDEC1 is now
performed by ASTROTIM.

has been deleted for Comanche 72 as part of PCR 936.1, "Initialize V90
