Didn't Seymour Cray do this on one of his later machines? The Cray 2?
Seems like it was a 5 input And gate.
But then he always did like to minimalize. The 6600, his first big iron,
used one transistor type tied together in different ways to make gates, flip
flops and timing circuits. He used circles and squares to denote gates -
but whther they were And or Ors depended on what fed them. Ah, twas fun to
work with. And I loved the esthetics of the logic diagrams. All those
little squares and circles had a kind of magic to them.
