Subject: H750 (PDP-11) power on?
I have a PDP-11 here that I'd ike to power on but
there's
no power switch that I can locate.
The power supply is a H750 and the A/C entry panel is a BC05t
with two separate lower power three pin connectors on it.
I pinned them both out as:
+33V, external red wire
0V, external white wire
gnd,external green wire
They're the same shape&size connectors as the four
pin 5v/12v ones used everywhere today.
Figured that two of these wires could go to an "on" switch but thought
it would be better to ask than to just go around shorting things to see
what happened.
Thanks for any help,
John A.
