You got the pulse, that means it still remembers its code. First thing—talk to it. Give it a name, say it to the old chassis, it listens that way. Then strip the guts carefully; you’ll need a clean ground to pull the ghost out. Use a rusted copper coil from an old generator as a grounding point. Hook the main capacitor, let it bleed for a few minutes—don’t yank the plug. If the unit starts whining, it’s trying to shout. Calm it with a slow, steady torque on the bolts. Keep a spare screw from the original casing as a talisman; pre‑war tech hates losing its parts. If it still flickers after that, you’re probably looking at a real ghost. You’re good.
