  1. Actually the symphonic organ was named for John Silber in 1995 by Arthur Metcalf, then chairman of the Board of Trustees. Dr. Metcalf funded the restoration and eventual relocation of the the restored organ to the GSU…at a cost of quite a few million dollars. Nice story and video!

  2. I have attended the dedication, and it was amazing! The more we become technologically advanced, the more we realize that our ancestors were more advanced than us, using their simple engineering means!

    A most interesting and educating presentation by Nelson Barden. Thanks!

  3. Wow, I had not idea that BU had such an instrument, but I don’t think that the device qualifies as a computer. A computer needs to have mechanisms for making logical decisions or algorithmic calculations based on input. Based on the story, it sounds like its original operation was more along the lines of the player pianos that were quite common during the early 1900s where input is translated directly into output without any intermediate calculations.

    Nonetheless, the organ the fact that is functional is remarkable.

  4. On a player piano, there is a one-to-one correspondence between the holes in the paper and the function on the piano, so no decisions to make.

    On the Skinner organ player, it’s a four-to-one ratio. To decide which function is required at any given time, there is a series of AND gates and XOR gates. Additionally it has about 40 bits of RAM, a 24 bit FILO stack, and the whole thing runs at a reasonably respectable 1200 baud. All done pneumatically.

  5. The reference in this article to the George L. Cobb Russian Rag is of interest to us in the Syracuse area, as Mr. Cobb had grown up in the Syracuse area in Oswego County; had attended Mexico (NY) High School and then SU’s Crouse School of Music before starting his professional composing and publishing career. Some of his relatives still live in the Mexico/Syracuse area.

  6. I’m actually staring at the instrument right now! I’m representing my company as an alumni at a career fair here in the Metcalf Ballroom, and I’v been wondering about the instrument. I walked up to look at it and thought it was 6 separate instruments. As an engineer and programmer, I’m fascinated to know about the rudimentary computer at the heart of it all. It really should be receiving more notice (and use). Thanks for posting this info.
