It was the Soviet minicomputer -- clone of DEC PDP-8/M but more bulky The capacity of the whole block is 57344 bit or 4096 twelve-bit words (4 Kwords). Ferrite cube is shown on 11 (opened) -12 (unopened) pictures. There were 8 ferrite core memory cubes in minicomputer. Total memory was 32 Kwords Legend reads as clone was made from minicomputer PDP-8/M that has been acquired from US sunken submarine “Saratov-2” was made in Central Research Institute of measuring equipment (ЦНИИИА), the city of Saratov.
