  Seymour Cray a legendás Cray1-et ehhez hasonlóan építette fel. Ő csak NOR kapukat használt.

  "The new machine was the first Cray design to use integrated circuits (ICs). Although ICs had been available since the 1960s, it was only in the early 1970s that they reached the performance necessary for high-speed applications. The Cray-1 used only 4 different IC types, an ECL dual NOR gate (4 input + 5 input, each with differential output), another slower MECL 4/5 NOR gate used for address fanout, a 16x1 high speed (6 ns) static RAM used for registers, and a 1k x 1 static 50 ns RAM used for main memory. In all, the Cray-1 contained about 200,000 gates, roughly the same as the Intel 386 of the 1980s."
