   1) NOTE: 00404* IS A PRIORITY ALARM… Hmmm…Any connection here to Internet 404 error origin? Probably not, but a cool coincidence > "in Cailliau’s telling [error 404 was assigned], “according to the whims of the programmer.” Client errors fell into the 400 range, making “404” a relatively arbitrary assignation for “not found.” Cailliau was adamant: “404 was never linked to any room or any physical place at CERN,” he wrote. “That’s a complete myth.”

   2) POODOO Alarm??? There are 6 refs for this code in the 1972 Apollo Guidance and Navigation Control Manual from MIT but no clear definition: strives-uploads-prod.s3.us-gov-west-1.amazonaws.com/19720…

   3) 001105/6 DOWNLINK/UPLINK TOO FAST – implied receiving systems could not keep up?? Buffer overflow?? Hilarious if true b/c the s-band phase mod telemetry speed was a mere "51.2 kilobits/sec (bad connection) to 1.6 kilobits/sec (good connection)." – en.wikipedia.org/wiki/Unified_S-band

   pps: Did the Apollo module have an annoying "check engine" light that made astronauts hook up an external reader to find out what was wrong (i.e., in so many 1990s+ vintage cars) 😉

   I started going on long duration TDY trips to KSC (from Orbiter final assembly, Palmdale Rockwell at plant 42), to support launch and preps on the orbiters. In late ’82, as I was walking thru the transfer aisle of the VAB (my comm and tracking systems office was in there), I saw a couple of oversized fork lifts jockeying Apollo simulators near the north exit. They were obviously storing them in empty spaces. After a few days in the evening instead of exiting to the south, I headed over to check out the LM ascent stage simulator (shimmying up an I-beam). I was able to get inside it (last time I’d seen it, it was powered up on display for the tours at the industrial area). Souvenir hunters had stripped most of the tong;e switch tabs and a lot of other small items. The RHC and THCs were gone too. But still, it was worth checking it out. I am not certain how long they stayed in those spots, but any appreciable time and dust was bound to build up. If those training cabins are at the Apollo museum, I don’t know- My last trip there was in 2001, when I was out to do Genesis spacecraft DSN interface tests with MILA. I didn’t see those simulators set up then.
