When you said "4. one vacuum tube", I had to look at my calendar. Nope, not April 1st.
Darn if there isn't a nine pin socket for one. But it just doesn't look like the screws Teletype would have used to mount the socket.
Interested yes, time for another project unfortunately no. In my youth I would have jumped at the thought of gear shift AND answer back features.
