Minuteman II Launch Control Computer

[Ben Sinclair]

I recently visited the Minuteman II launch control facility in South
Dakota, and was curious about the computers used there.

Here's a photo of the rack, with the Boeing part numbers visible:

Some Googling of those numbers didn't really reveal much. People love to
talk about the guidance computer in the missile itself, but I can't find
much about what they used when turning the keys.

I like the little placard on the computer about encrypted data in memory.
The whole place is worth a visit if you're out that way.

Does anyone have more information on these? Thanks!
