Apollo Guidance Computer Part 3: Main Bus B Undervolt

Video Description

In preparation for the AGC power up, we test the alarm module B8, simulate the Apollo 13 main bus undervolt, and discover that our memory is faulty. And we find out how much our AGC did originally cost. Frequent comment answers: Yes we know about Francois Rautenbach and the Block I core ropes (https://youtu.be/WquhaobDqLU). These ropes are also from Jimmie and not compatible with our Block II computer Yes we are in contact with Fran https://youtu.be/UjcfepTdvZI (and several others) about their superb DSKYs replicas.
