Another amazing gift from Geert, this is my first real DEC peripheral for the PDP 11/44!! Yay!
Running tests for the controller
I inserted the M8256 controller in an Unibone testbed (see here how to set that up):
I then started the cpu20_xxdp_rl0_dl11.sh script to get the Unibone to emulate a CPU and a DL11 serial port. This now boots xxdp. I then start ZRXBF0.BIC which should test the controller.
