The DEC PDP systems never cease to be a source of inspiration for me and the above example of a PDP-7 system at Columbia’s Electrical Engineering department is no exception. I am not sure who took this photo as there was no credit included (source: Columbia Computing History). It would be tempting to gut the cases and fill them with modern studio equipment if you could find a nice used example. Also, if you have an oscilloscope in your computer you win.
For you Mac heads out there, this is your great-grand daddy. A PDP-7, referred to as the “Unix Genesis Machine”, was used by Ken Thompson and his team in 1969 to develop the Unix OS (a very early precursor to what would become Mac OS X).
