using additron tubes the additron was an electron tube designed by dr josef kates circa 1950 to replace the several individual electron tubes and support components required to perform the function of a single bit digital full adder dr kates developed the additron with the intention of increasing the likelihood of success and reliability while reducing the size power consumption and complexity of the university of toronto electronic computer utec 1 production edit the additron neither went into production at the canadian rogers vacuum tube company where the prototypes were built nor was it used in the utec machine it did make a widely publicized appearance at the 1950 canadian national exhibition operating an electronic game of tic tac toe dubbed bertie the brain to show the marvels of
