Our core memory module has a fault. We deep dive into its construction and make several measurements to find where the problem is. It will be helpful to first watch my core memory video: https://youtu.be/AwsInQLmjXc . This blog article from Ken Shirriff goes into even more details about the AGC core memory: http://www.righto.com/2019/01/inside-apollo-guidance-computers-core.html

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 but are 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.
