DEC actually made a microprocessor implementation of the PDP-11 processor, called LSI-11. It has two chips, and is functionality equivalent to the large thing. Unfortunately, DEC was in a complete disregard of personal computers or workstations at that time, I don't think they made workstations with it. Otherwise it could be another legend in computing history: a PDP-11 workstation! Never happened.
Here's S100 computer board built around this microprocessor with a great introduction to the hardware details. http://s100computers.com/My%20System%20Pages/PDP11%20Board/PDP11%20Board.htm http://s100computers.com/My%20System%20Pages/PDP11%20Board/P...
