Hello list,
while surfing for PDP-11 information yesterday, I came across pictures of a dec data
system cabinet
with the vertical grey panels, one of them having three distinct switches.

So far, I couldn't find any hints on the web to figure out what they're used for.
They only seem to exist on those larger business cabinets as far as I could see.
Does anybody of you know about their functions?
Kind regards,
Pierre

Seems I can't see any pictures unless I sign up... :-(

I suspect what you are seeing are the switches that are hooked to the
M9312. One switch is for selecting if you want automatic boot on power
on, one switch is a plain boot switch, and I can't remember what the
third does.

If I remember right, the unlock releases a mechanical interlock that blocks the other two
switches. If you press unlock, you can then press ?initialize? to boot the machine, or
the power on/off switch.
