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
