The M-54 general-purpose transistorized digital computer is described. This computer is a modification of one of the first transistorized computer models developed at the Moscow 'Order of Lenin' Power Engineering Institute. This single-address machine is capable of executing 16,000 additions, 3,000 multiplications, or 33,000 logic operations/sec in the fixed point mode. In the floating point mode, 5,000 additions/sec are possible. The machine uses 5,200 transistors, 13,500 semiconductor diodes, and 100,000 magnetic cores. The arithmetic unit has a parallel action adder-accumulator acting on 40-bit words. The main core memory has a capacity of 4,096 20-bit words. Access time is 10 microseconds.
