Brazillian developer Luizão releases schematics for a scaled-down version of the core rope memory module used by NASA in the 1960s. Deployed in interplanetary probes and the Apollo Guidance Computer, core rope memory is woven read-only memory that uses magnetic cores and wires to store data. Luizão’s implementation has 12 addresses x 8 bit values (96 bit memory)—a rotary dial cycles between data stored in each core, which is indicated by varying light combinations at the top of his assembly.
