We bring up the first memory section, fixed core rope memory. This is the "ROM" that holds the programs. Although based on ferrite cores, this is read-only and very different from the erasable core memory. Our AGC actually did not come with flight rope modules, but instead with a pair of Raytheon boxes used during development for simulating the final ropes. Unfortunately these boxes are undocumented and of much lesser build quality than the flight hardware, which should keep us on our toes. Thanks to our sponsors Samtec for the connector pins and PCBway for the monitor PCB: https://www.pcbway.com
