NUSSE was the Norsk Universell Siffermaskin, Selvstyrt, Elektronisk computer which was a copy of the UK Birkbeck College design possibly the first clone in the world circa 1952-1954.

There are two references in UK books by A. D. Booth to this computer,

  1. "Automatic Digital Computers" 1953 1955 reprint chap 35 p270
    "Up to the present, two copies of APE(x)C are in existence. The first at the Norwegian Board of Computing Machines, Oslo, under the direction of Dr. T. Hysing, is undergoing tests. The second is in general use at the laboratories of the British Tabulating Machines Company."
  2. "Faster than Thought" 1953, 1955 reprint chap 13 p171
    "A.P.E.N.C. Norwegian Board for Computing Machines
    The machines are properly engineered versions of S.E.C. built with miniature components. The digit repetition rate is 50kc/s. Storage capacity is of the magnetic drum type and gives 512 thirty-two-digit binary numbers. The machine is provided with a high-speed, short-cutting multiplier and takes 500usec for addition and subtraction, and (n x 500) usec for multiplication, where n is the number of "live" digits in the multiplier.
    Only 415 valves are used, including all diode elements. Power consumption is 1.5KW
    Input and output equipment varies with the requirements of the users, three types being available---
    1. Punched-paper tape read photo-electrically as input, output to reporforator or teleprinter.
    2. Magnetic-tape input and high-speed output. Printing via a teleprinter.
    3. Punched-card input and intermediate store. Output via Hollerith tabulator."
