545 Technology Square
Main Street, Cambridge MA

In the fall of 1968, while I was still an undergraduate student at MIT, I interviewed for a part-time position at the IBM Cambridge Scientific Center in Technology Square, across Main Street from the main MIT campus.  My experience with installation and operation of OS/360 at the MIT Computation Center was something that they needed, so I ended up sharing a desk with Bob Seawright, an IBMer from the Boston sales and support office who was another occasional worker.  Little did I know at the time that I was embarking on a substantial career in technology.

Reproduced here is an edited and extended series of personal and technical notes that I originally put together in the later 1980s, at the prompting of Melinda Varian at Princeton University.  Melinda was (and perhaps still is) an active user and vocal, long-time proponent of the IBM Virtual Machine Facility/370 time sharing system.  The SHARE and GUIDE papers Melinda authored provide an important framework of the VM/370 user community and follow the history of IBM's VM technology well beyond August 1976, when many of the original developers and support people, including myself, moved on to other jobs and/or other companies.

Much of the information here is perhaps redundant with my more recent Web pages, but I was surprised at the detail and perspective in these "memoirs" from 30 years back.

  • In the later 1960's Technology Square was a commercial office complex managed by Cabot, Cabot & Forbes.  Three multi-story office buildings surrounded a raised central plaza, with a modern 3 or 4 story building in the front centered on Main Street.  (The Polaroid Corporation history reports that they moved their main offices to 730 Main Street in 1939, so the 1960s-era Tech Square complex was very likely their design.)
  • MIT leased the top floors of the east building, 545 Technology Square, also called building NE43.  The first floor was a cafeteria restaurant.  IBM leased the second, third, and fourth floors, with a Central Intelligence Agency office located in the northwest corner of the third floor.  The lower floors of the west building housed a BayBank facility, and the central buildings housed the corporate offices of Polaroid Corp.
