This is awesome. Thanks for your work on this. I shared your video on my Twitter - I'm sure others will be interested in seeing these capabilities.
Nice :thumbup:
It looks you used another sim for the first part of the video, am I wrong here?
What's with the floating box?
Should be 1x4x9? :shrug:
Project Apollo NASSP 8.0 Alpha - Masking the Abort Discrete on Apollo 14 - YouTube
A short video with NASSP and the AGC emulator showing the Apollo 14 procedure that was used to prevent an abort caused by their faulty abort button. It also shows what happens when you don't use the procedure and follow the nominal timeline for Powered Descent Initiation. Spoiler: the computer will start the abort maneuver at the instance of ignition.
For Apollo 15 and later the computer had a simple crew procedure for ignoring both of the abort buttons. This is just one of the fun things you can do with the flown AGC software!
...the DSKY should be displaying P71.Fortunately, another path in the Abort Monitor Routine to close this window of vulnerability was found -- MODEREG: the Mode Register memory location that held the number of the program or "major mode" that was currently running. That register was accessed mainly for the PROG display on the DSKY, but was also checked by the Abort Monitor Routine in case P70 or P71 was already running. If an abort was the current major mode, there was no need to start a new one.
I'm not claiming I know the AGC, but I think you might have a problem. I remember reading that they changed to P71 for ignition... but you still have P63. I went and found this page which details this issue, and according to this part...
...the DSKY should be displaying P71.
