Hi all,

I've try some procedure in with  my Apollo 8 in LEO.

Following the G&C CheckList part 8 from Apollo 16, I've try to start a PTC using P20 program in vAGC but it's seems that this one is doesn't working.

Using V37E20E the COMP ACT light stay one for few second and then instead of the possibility to enter the desired option appears a 50 18 with three parameters.

Someone else has been tried this P20 before ?

Apollo 8 and Apollo 16 use different versions of the AGC software. The Apollo 8 one is much older and has an entirely different P20.

Hi Bertog!

Apollo 8 uses colossus 1 A_ 249 version which is quite basic than the Artemis 72 used on later mission (no GNCS PTC and Orb rate, no minkey and so on...)

For Apollo 8 I suggest you to use those docs:

or the checklist I'm still working on in your project apollo repository:Doc\Project Apollo - NASSP\Check List\G&C checklist\colossus_1A_249
This latest is not complete because it's a huge work to copy the pdf doc, test the procedures with home made (and sometime broken Bangs Head) scenarios and then to write the doc in order to be usable by the simmer.
But I hope it will help you.  Happy
