Did you know that the 8088 which formed the basis for the IBM PC, released in 1981, just a decade after Apollo 11's trip to the Moon, had eight times more memory than Apollo's Guidance Computer (16k, vs the Apollo's 2k). The IBM PC XT ran at a dizzying clock speed of 4.077MHz. That's 0.004077 GHz. The Apollo's Guidance. Restorers Try to Get Lunar Module Guidance Computer Up and Running In 1976 in a warehouse in Texas, Jimmie Loocke bought two tons of scrapped NASA equipment. Years later he realized it included a computer from an Apollo lunar module, like the one used to guide the lander to the surface of the moon during Apollo 11. Fifty years after that mission, computer restoration experts in Silicon Valley are trying to get his computer working again
The AGC was designed as an airborne digital computer to control, test, and operate the Apollo lunar module's guidance system. The general-purpose computer used a binary 15-bit format for parallel word transfer and instructions using single addressing mode. The AGC's data and instructions were stored in memory. The memory structure consisted of several fixed thousand words and 1,000 words were erasable. Included with AGC was a small number of central addressable registers for data storage. . For such a crucial function you needed as much reliability as possible. Because space (inside) was extremely limited, it needed to be extremely compact Core rope memory is a form of read-only memory for computers, first used in the 1960s by early NASA Mars space probes and then in the Apollo Guidance Computer (AGC) and programmed by the Massachusetts Institute of Technology Instrumentation Lab and built by Raytheon. Software written by MIT programmers was woven into core rope memory by female workers in factories. Some programmers nicknamed the finished product LOL memory, for Little Old Lady memory
