They're around. I had one when I was little and it was ok but kind of 
clunky. The box was odd, it only had 16 (maybe 18?) bits wired on the 
backplane and the power supply was a linear rock if I remember right.

Still, it ran Rt11 pretty well. But an 11/23+ would give you the VM: ram 
disk driver that allowed you to just copy the whole OS to memory, boot, 
and run fast!.
