PDP-1 speed #339

From a reader:

I came across a section that might have a technical error on the "game loop" pattern page, on the sidebar it reads "The PDP-1 was a 2 kHz machine", I was intrigued by this so I did some further research and from what I can find is the clock speed appears to have been closer to 200 kHz: "Add time: 100,000 add/s (5 us cycle time - 200 kHz)" from http://www.computerhistory.org/pdp-1/specifications/
