Cracking the Code: Saving Apollo's Core Rope
A team of retro hardware enthusiasts, led by CuriousMarc, has successfully preserved Apollo Program software by building a core rope reader from scratch. After recovering the contents of read-only core rope memory modules, the team needed a way to read more modules. Mike Stewart took on the challenge and built his own reader, but encountered a bug in the block II design of the core rope modules. By recompiling the FPGA code, the bug was fixed, allowing the conservation effort to continue.
