WebAnswer (1 of 2): Quora User's answer is spot on as to what the ENIAC used, but he neglected to provide the physical dimensions. So, for the 6SN7 (of which ENIAC used several thousand), those are dual-triodes in a T9 bottle -- 1 9/32" diameter of the base (1 3/16" of the glass bottle itself), 2 3... WebJun 21, 2024 · Ordinary tubes as used in '40s and '50s computer designs are neither as powerful nor as fast. Typical tube designs of the era have large output impedance along with high output voltage swings and relatively high input capacitance (worsened by Miller effect). Those things limited the speed of tube computers.
