VLA Monthly Progress Report, April 1977 Photo

The computer room at the VLA site in April 1977. Jim Torson is at the main console of the DEC-10, while Jon Spargo mounts a tape. Note the phone that came with the computer, built into the console so the operator could easily call for help. Barry Clark recalls that "Two or maybe three of the 36" wide racks held the main memory, I think at 1 M 36 bit words each (4.5 megabytes)." First fringes with the VLA as a 4-element interferometer were obtained on 18 October 1976, and in April 1977 data came from nine different programs of scientific observations, each using six antennas.
