Editing Twistor memory (section)

===Manufacturing===
Manufacturing core was a major issue. The X and Y wires had to be threaded through the cores in a weave pattern, and the sense/inhibit line passed through every core in a plane. In spite of considerable effort, no one successfully automated the production of core,{{citation needed|date=May 2016}} which remained a manual task into the 1970s. To increase [[memory density]] one had to use smaller cores, which greatly increased the difficulty of wiring them onto the lines.
