I was there as well. I punched the cards and read the core dumps and programmed in machine language using the front panel switches and lights. I programmed the Burroughs machine in Algol, and the IBM in assembly language (BALR, USING); the GCOS operating system which gave the GCOS field in the Unix/Linux /etc/passwd file its purpose and name; and the Univac 494 with the FASTRAND II drums. It was the most fearsome computing equipment I've ever encountered thanks to its spinning tonnage.

You are seen.
