Guys, please, note, only Memory plate is offered for sale. I have a photo of the technical documentation, it is in Russian.

If you need it, please, let me know and I will send it over. I do not have hard copy manual. You will receive a Memory

Plate only in pristine, well preserved, vintage condition as shown on picture gallery.

In case if you will need technical documentation (manual) for your reference (please, note, it is in Russian),

I uploaded it on google drive, here is the link to the archive:

1Cores with a rectangular hysteresis loop ЗВТ-1К 1.0 х 0.7 х 0.35 mm are used as a memory element in a ferrite matrix. The cores are structurally integrated in one frame of the 1M-2 type by a common system of wires and form a matrix with a capacity of 4096 one-bit words. 64 coordinate wires pass in the matrix along the "X" and 64 ones along the "Y", forming an address grid of 64 x 64.

2The output winding for improving the signal-to-interference ratio is composed of two unconnected parts, each of which covers 2048 cores.

3 The ban winding is also divided into two parts and connected to two independent from each other ban current generators. This helps to improve the ban pulse parameters and facilitates the thermal operation of the unit.

4The ban and read winding are sewn in such a way that simultaneously two windings cover only 1024 ferrite cores. This reduces twice interference from half-selected cores and parasitic pickups in half-cycles of reading and writing.

Сondition: Perfect, vintage condition.
Please, note, last two photo are not the actual item offered for sale, last photos used for reference only (for demonstration purposes).
