There are still PDP-11's working somewhere..........

NASA facilities everywhere. The launch control center at Kennedy.

There are even PDP-8s in use on scavenged parts.

I keep a PDP-8 card on my shelf at home to remember the good old days. We transitioned from PDP-8 to PDP-11 when I worked at Signetics.
