2nd, a hardware emulator running a simulator written in 6809 assembly

I would call that a software emulator; the fact that it runs on some microprocessor eval
board doesn't make a difference. Running SIMH on a Beaglebone would be analogous
(though easier).
When you said "hardware emulator" I figured you meant an FPGA implementation of
a VHDL or Verilog model of the machine. There are a bunch of those for a variety of DEC
computers. One I have looked at is this one: http://pdp2011.sytse.net/wordpress/ which
incidentally is also configurable to implement a choice of PDP11 model.
