I have followed this thread, but have not been interested enough
to keep any of the old posts.

Just for curiosity, which Key codes were used for the PDP-11
systems?  I used to have some PDP-11 racks for RL02 drives
with a Qbus PDP-11/23 inside and I thought I remembered that
XX2247 was used on them, but I would just like to know for sure.
Actually, the more I think about it, just an Alan key was used.

The above post suggests that XX2247 was used for the PDP-8.
If so, was any specific key used for the PDP-11?
