The Code 1202 glitch during the LM descent to the Moon

Spread the love

Why did the LM’s “mini” computer throw a restart glitch during the descent? Eyles — who wrote the code — tells the story:

We are here discussing the LM’s mini computer, which used IC’s to effect an unprecedented small size (and “only” 70 lbs, in a box Eyles describes as 1 ft x 2 ft x 6 inches):

Spoiler alert: a switch had been bumped, a radar overloaded the tiny 36,000 word memory and reset was triggered. Armstrong took over manual pilot and rode over a crater that was headlined at the time as an emergency leading to a blood pressure and heart rate surge.

A successful landing was effected (I recall, listening after church as my late Dad tuned on a short wave band) then that evening we listened in a darkened living room as the radio let us hear the first Moon Walk.

A moment of triumph that perhaps can help us rebalance and refocus towards progress. As I just noted in a post of the live stream:

Let us remember and let us learn. Hopefully, back to the Moon then onward to Mars, the Asteroid belt and solar system colonisation across this century — our real hope. And, a positive focus going forward.

Food for thought. END
