Editing Twistor memory (section)

===Operation===
Writing to twistor was effectively identical to core; a particular bit was selected by powering one of the twistor wires and one of the solenoid loops to one half of the required power, such that the required field strength was created only at the intersection of the two.

Reading used a different process. Unlike core, twistor did not have a sense/inhibit line. Instead, it used a larger current in the solenoid, large enough to flip all of the bits in that loop, and then used the twistor wires as the read line.

Twistor was thus read and written one plane at a time, rather than in core, where only one bit per plane could be used at once.
