Program Alarm 1202
A playable model of the Apollo Guidance Computer's executive during the lunar descent.
What it does
Relive the computer alarms that nearly stopped the first Moon landing. A simplified Apollo guidance computer runs its jobs while you slide up how much time the landing radar steals, and you watch low-priority work pile up until the real 1202 or 1201 alarm fires. The restart clears everything but the essential jobs, so the landing carries on, and you can compare that design against one that aborts and one that takes turns blindly. A DSKY-style display panel and an Apollo 11 timeline suit history and computer science classes.
Good to know
The size of each job is estimated to match the real load, not taken from the actual flight software.
