For several years we had UCSB’s IMP control panel hanging in our office as a wall decoration (it belonged to Larry 
Green, one of the UCSB IMPlementors). I still have the manuals. The actual IMP with 56Kbps modem was in a huge rack 
with lifting eyes for a fork lift, and weighed about 500 lbs. Every IMP had a unique customized host interface, which 
packetized bit-serial data from the host over the host’s usually proprietary I/O bus. 

I know of at least one actual hardware PDP-10 (Not PDP-11) that is still connected to the public internet.

Mine will be if/when I ever get it working.
