So, does the move to Git mean I should turn off my weekly backup of the CVS tree? It's been running quietly for years since I last had time to do any Orbiter stuff Happy.

Archive.org is building up a NASA audio collection, so some of these might come in useful:

I assume no-one has changed that, but I still haven't got Orbiter working on my new laptop... I should give it a try again when I get the chance!

BTW, I was at the Nevada Test Site recently; I was hoping that I might see where NERVA was tested, but I don't even know whether there's anything left now.

Did get to Sedan Crater, which is one of the places the Apollo astronauts visited for geology training... with all the nuclear test craters around there I can see why NASA thought it was a good place to prepare for moon landings!

There's a flag in the scenario file indicating whether there's an HGA or not.

BTW, there's some interesting stuff about DSKY reliability on NTRS:

Apparently it used a staggering number of relays (presumably to turn the lights on and off) and could theoretically burn through the maximum cycle count for those relays in a few hours if you left it monitoring rapidly-changing values like time.

Here's more on the Block I:

Quote
The power supply consists of two parts. Input to the power supply is +28 vdc from the spacecraft main d-c bus. The two sections provide +13 vdc and +3 vdc. The +13-vdc output provides power to the DSKYs and, in conjunction with the +3-vdc power, to the logic circuits. The +3-vdc supply provides power to the timing section as well as to the logic circuits. During standby mode of operation, the +3-vdc section only is operated; thus, power consumption is reduced by approximately 100 watts.

So in that case at least the DSKY was powered via the AGC.

But there is another coding request I would like to make: I think that the three green lines and the three green lights (PROG, VERB, NOUN) on the DSKY display should not be on/visible in case the corresponding circuit breakers are pulled out on panel 5. Could somebody change this? I think it's not a big deal but I sadly can't do it due to lack of coding knowledge.

The DSKY lights are on any time it's powered, and it's powered through the GaugePower object which just takes power from both main buses; it just needs to be modified to take power from the correct place, but I don't remember ever finding out where the real DSKY got its power from.

See saturn.cpp around line 1010.

There's a caution and warning base class which is probably where you'd want to start looking; I think we model the two power supplies but I don't know whether either of them can fail.

If you can make it work, go ahead Happy. You might want to investigate why it would fail and see if we can simulate the mechanism.

Sounds like a good idea!
12  Project Apollo - NASSP / Project Apollo - NASSP News & Discussion / Re: Does the CSM panel works? on: April 03, 2010, 01:24:23 AM
I did start working on emulating the tape recorder, but didn't get very far Happy.

Very impressive!

Cool, that's one of the major things that's been missing for a long time!
