PDP-11/70 Panel Research

The console panel of DECs PDP-11/70 is quite iconic.

There are many of these in collections, usually saved when machines were upgraded and later dismantled.

Projects like "BlinkenBone" or "PiDP11" try to emulate this front panel, connecting panel hardware to a modified "SimH" emulator.

However, beeing 100% faithful requires to explore behaviour of a real existing PDP-11/70 in a lot of special situations.

These tests where performed at the Living Computer Museum in Februar 2018. The PDP11/70 is  "Miss Piggy", a historic Microsoft server.

Special thanks to Mike Hill, who designed lots of the test sequences, and ofcourse to the patient LCM staff!

These pages document the test and their resulting videos
