Hello again,

Many of you are into PDP-11, both the blinkenlights
variety and the simpler dump front panels, as well as
VAXen and such with console-based front panels.

Do any of these machines, if they have a really bad
problem that might preclude the use of the console,
flash an LED to mean something?

In particular, do any of you have familiarity with
systems that flash the on or power light as an
indicattor, sopecifiecally, of a power supply
problem?

Would anyone venture what a 2 Hz flash rate on the ON
LED of a Prime might mean?

Thanks again,
-doug q
