Description:At the beginning of the 1990s, there were efforts to develop a new astronomical data processing package, referred to as AIPS++. The vision of AIPS++ was to improve research productivity of the radio astronomy community by unifying new astronomical algorithm and software ideas with state-of-the-art computing technology. It was undertaken as a cooperative venture, with multiple observatories around the world committing staff time to the project and sending people to Charlottesville for a year-plus to work jointly on the project. This photo was taken at the 12-14 December 1994 AIPS++ Review Panel meeting. [show more]

Description:The Charlottesville computer room in 1967. Standing is Sandy Braun, and at the console is Mary Jennings, an IBM employee. There were computer operators on duty 24/7, and tapes of data taken in Green Bank, at the 140ft, the 300ft, and the interferometer, came over daily on the shuttle to be processed in Charlottesville. Processing programs were handwritten on paper and transferred to cards using a keypunch, then read into the computer from decks of punched cards to process the data from the tapes. [Note the punched cards in Sandy's hand and in the box just to her right.] The output, often spectral data from our autocorrelators, was hundreds of pages of numbers which had to be assessed by eye for quality control. The trick was to get the stacks of paper back to Green Bank in time for the observers to change their observing program to take the new data into consideration. To Mary's right is the console. The system was controlled from it - the operating system or diagnostics were loaded by selecting various switch options. Mary is at the main terminal with a "standard" setup for those days: a teletype keyboard with printer output. Operating system directives were entered here by the computer operator, since this was prior to the days of video terminals (aka Cathode Ray Terminals or CRTs) with associated keyboards. The computer is an IBM 360 series, and the operating system was known as OS/360; programs were probably written in PL/1 or Fortran. [show more]

Description:Once each year the CIS systems administrators have a face-to-face meeting to discuss Common Computing Environment issues. The meetings rotate between sites and the March 2004 meeting was in Green Bank. Attendees had a high and low altitude tour of the GBT on a somewhat damp day. After returning from their vertiginous trip to the top, the red hat group contemplated engineering work in progress on the track. Left to right: Dave Brown, George Martin, Tracy Halstead, Ruth Milner, Martin Pokorny, and their GBT tour guide, Dave Rose, in the white hard hat. [show more]

Description:In late September 1976, with early VLA construction happening outside, Barry Clark and Linda Blankenship [Sowinski] work at the site. Barry recalls that his terminal was a SuperBee, connected to the Modcomp real-time system, and that the terminal on the table to his left was connected to the Dec-10. Both were dumb terminals connected to rack-sized computers. [show more]

Description:This is an early commentary on data storage at NRAO. This memo, affectionately known as "the tape memo," outlines procedures and protocols for the multiple users who will store files on a recently-purchased MTA-2 magnetic tape.
Thanks to Barry Clark, who kindly provided the following additional information about the Charlottesville computer room in 1960: "The machine was a System 360 Model 50. The Mark I VLB correlator ran on this machine, at about eight or ten times slower than real time - not real swift. I hadn't remembered the front panel having so many lights. At any rate, it was the first front panel I encountered on which the lights were utterly meaningless except to a maintenance engineer. The console was not a teletype. It was a modified IBM Selectric typewriter. A great advance over the teletype. You could type as fast as you wanted - on the teletype, you had to adapt your rhythms to the machine." [show more]
