Argh, my memory is failing me. The BA11-S technical info is in the "PDP-11/23B
Mounting Box Technical Manual", EK-23BMB-TM-001 - which is also not online,
and also available as fiche.
I have found someone who has the BA11-N TM, and is apparently willing to scan
things, so maybe we can get that one.
