Techno-zombies and Pluribus

I'm always amazed at how long a piece of apparently obsolete equipment can remain in service, especially in government service. Bruce Schneier's blog listed a link to NSA's 1991 video catalog at The catalog grants us an interesting if spotty view into the world of crypto gear and classified data collection systems.

I was particularly astonished to see inclusion of a video about the Pluribus - a long-obsolete Arpanet-era packet switch. I worked on the beast: it was overbuilt and underpowered. And unreliable (more on that another time). In the ideal world of tech, such obsolete junk should have been recycled by 1991. I was optimistic.
