@ricci genuinely surprised these guys don’t make one; would you settle for the pumpkin spice chemtrail controls?

@dan @ricci well since you mention it… I also made these stickers 🙃
the switch & the stickers (& a life-size standee of Margaret Hamilton & a DSKY) were for a display on the Apollo Guidance Computer that I put together for a recent vintage computer fair here in Canberra 💁♀️
@itgrrl @ricci also, this reminds me of a story I recently learned about and had been meaning to post about. Did you know that Margaret Hamilton used to bring her daughter to the lab when she was working nights and weekends, and let her play with the AGC simulator?
Her daughter crashed the simulator by accidentally invoking program 01 and resetting the guidance system to believe it was back on the launch pad.
Hamilton felt that was a pretty serious bug but was told "no, there's no way a trained astronaut would accidentally do that."
A trained astronaut did, in fact, do precisely that while Apollo 8 was on the way back from the moon.
She was allowed to fix it for Apollo 9.
@dan @itgrrl @ricci Oh boy, I get to cite the Apollo Flight Journal, complete annotated radio transcripts of every Apollo mission.
A sleep-deprived Jim Lovell was performing a navigation measurement of Alpheratz, star 01 in the computer. But he omitted part of the command sequence and instead entered program P01, a prelaunch initialization program.
The astronauts and mission control spent much of the next three hours recovering from that.
106:27:22 Lovell: Houston, Apollo 8.
106:27:24 Collins: Apollo 8, Houston. Go ahead.
106:27:28 Lovell: Roger. For some reason, we suddenly got a Program 01 and a 'No Attitude' light on our computer.
106:27:35 Collins: We confirm that.
[…]
106:30:04 Collins: Okay. Jim, while we're working on this procedure, we'd like to know did you select 01, did you get a Verb 37 Enter. 01 Enter? [Pause.]
106:30:15 Lovell: Let's see, I'm not too sure, Mike. I might have done that, yeah.

@stonebear2 @dan @itgrrl @ricci My mother just mentioned yesterday, as an aside in another story, that she watched some big rocket launch while in Florida for Christmas in the late '60s.
Mom! That was Apollo 8!
@gparker @itgrrl @ricci yes, the Apollo Flight Journals were my nighttime insomnia reading for a while.
You can also tell from the subsequent transcripts that Borman was pissed off at Lovell for a while, but by the end of the mission they had all calmed down enough to joke about how he must have done it because he was trying to get home sooner by teleporting back to the launch pad.
@ricci @dan @gparker oh yay! you get to be one of today’s lucky 10,000, enjoy! 🎉🎉🎉
I had it running for my AGC display at a local vintage computer fair last year & it really helped set the mood – I highly recommend listening with headphones on
the audio files have been uploaded to the #InternetArchive as well, so if you’re really determined you could cue them all up multi-track audio software & play around even more
@dan @ricci @gparker thank you! 💕
my friend @jambulance did the 3D prints – the full-size DSKY is a WIP with electronics & displays still to come, and the baby DSKYs were just too cute not to print a bunch 😍
we ended giving the baby ones away as donation incentives to encourage folks to tip in more than the usual recommended “gold coin donation”^ for the exhibition

Planning for a one dollar coin commenced as early as the mid-1970s. It was recognised that Australia needed a higher value coin which could be practically used in coin operated machines and to replace the one dollar note which had a short service life through high use.Mr Stuart Devlin was commissioned to design the reverse of the new coin. The five kangaroos design was chosen from submissions received from the designer.This denomination has since been used for commemorative designs.
And the UI devs congratulated on a job well done.
With musical fanfare for defeating the final boss. 😁
@dan
Let me point out that the source to this story is told by Hamilton herself in "Oral History of Margaret Hamilton", p28, by the Computer History Museum.
