研究人员成功恢复并运行了从阿波罗制导计算机（AGC）旧“绳索”存储模块中抢救的数据中的原始软件。**Sundial-E**，相当于登月舱的Aurora 12的指令舱版本，包含完整的AGC测试套件和指令舱子系统测试。**Sundance**，来自阿波罗9号——首次在太空中的登月舱测试——正在从回收的模块中重建，并正在努力获取剩余部件。最重要的是，**Retread 50**，*第一个*可用的Block II AGC程序，尽管绳索受损，但已被恢复。团队利用奇偶校验位进行修复，成功在现代AGC上运行了Retread 50，并确认它通过了所有原始测试。这些恢复成果，记录在GitHub上，代表着数字考古学的卓越成就，为太空飞行早期计算提供了宝贵的见解。

一个黑客新闻的讨论强调了CuriousMarc的迷人“阿波罗制导计算机修复”视频系列。用户称赞该系列是对已经熟悉阿波罗历史的人的深入研究，特别是对那些具有电子、计算机科学和无线电通信背景的人有吸引力。它被誉为YouTube上一种独特且有价值的内容。对话延伸到进一步学习的书籍推荐：“数字阿波罗”（人机交互与系统工程）、“Sunburst and Luminary”（一位软件工程师的回忆录）以及Cox和Murray的“阿波罗”（项目管理与工程）。评论者还深入探讨了早期计算的历史，争论使用继电器与半导体构建计算机的可行性，并强调了早期存储解决方案（如绳索存储）的巧妙之处。讨论触及了AGC所代表的令人难以置信的工程壮举，将其计算能力与现代设备（如USB-C到HDMI电缆）进行对比。

Sundial -E (recovered from ropes at the MIT Museum)

Sundial-E is the Command Module equivalent of Aurora 12 which was written for the LM. It contains the full test suite of the AGC, as well as the tests for all the subsystems of the Command Module (Aurora would contain the same AGC test suite, but would have tests for the LM subsystems, which are very different). The recovered software ran on our successfully AGC after we dumped it from the original ropes.

Sundance (recovered from ropes loaned by AGC creator Eldon Hall and AGC programmer Don Eyles)

So far we have been able to recover 3 of the 6 rope modules of Sundance, the Apollo 9 LM program. Apollo 9 was the first test of the LM in space, Earth orbit. The modules we have differ as of their version of Sundance. We are in the process of disassembling the code we recovered. We have located 3 rope modules that would complete the software (which fits in 6 rope modules), and will be trying to get access to them to complete the recovery.

Retread 50 (recovered from ropes at the Computer History Museum)

Retread 50 is the first functional program written for the Block II AGC. This was used to test the functionality of the newly developed AGC. Parts of the ropes were damaged but we were able to recover the original content using the parity bit. We ran the repaired software succesfully on our AGC, and yes, it passed all the tests.
