Incorrect size

The stated capacity is incorrect -- it's 4096 bits, not 1024. Two ways to see that: (1) 6600 memories were 4k by 12 bits, using 12 of these core planes, and (2) there are 64 wires coming out each side of the plane, so there are 64 X and 64 Y lines, for a total capacity of 64*64 or 4096.
