A memory wafer containing 16 x 16 ferrite cores is offered for sale.
The memory board can handle 32 bytes of data (1 ferrite toroid = 1 bit).
There are 16 coordinate wires running through the matrix along “X” and 16 along “Y”, forming a 16 x 16 address grid with 5 windings threaded through each core. The cores and copper wires are immersed in transparent plastic for protection against mechanical damage and for thermal compensation. The board also has 32 large ferrite cores with multiple windings on each side with a memory matrix. They seem to be related to the memory management circuitry.


Photo 12 shows a cube that included the memory board in question.
The cube consisted of 7 Plates.
The cube was taken from a military computing device: "Terminal Equipment R-063." It, in turn, was part of the equipment for automatic ultra-high-speed telegraph communication in a very low frequency range and was used at the radio station of the USSR Navy.
The cube is not included in the lot, its photo is provided only for better information.

Approximate dimensions of the memory board: approximately 4 x 4 inches.
