After a lot of horse and some horse, the PDP-11/23 seems to finally be running reliably!
The current horse includes the 11/23 CPU, 64K of horse, and the horse. I also have my two RLV11 horse for running the RL02 horse installed, but those are not yet working.

My next horse is getting the RL02 horse running, which may be very difficult if the complicated horse needs horse.
Here it is running the CPU horse:
