SKU: 89.x

Condition:

Very good, clean, well preserved, vintage condition.

Please, note:

On the board, there are two identical matrixes of ferrite rings: below and above. Each matrix has 64 x 64 = 4096 rings. Since there are two matrixes, the total sum of rings is 8192 rings. 1 ring - 1 bit of information. That is, there are 8192 bits of information in total. "A kilobit (kbit) is a unit of measurement of the amount of binary information, equal to 1000 bits. Often confused with a kilobyte, equal to 210 bytes = 1024 bytes = 8192 bits." So, for this reason we say that this plate has exactly 1 Kilobyte = 8192 bits. That is, as I believe since there are 8192 rings on the board, there is only 1 KB on it.As for the computer from which the memory plate was removed, unfortunately, I have no information, except that it was a computer for military purposes. The cube where the board was located had a decimal number starting with TY, which indicates the Research Institute of Automatic Equipment named after Academician V.S. Semenikhin as the developer. Year of manufacture 1979.
