DEC VRE01 terminal documentation

You may want to see if the PLATO terminal documentation is any help, look on Bitsavers under University of Illinois.  Those plasma display power supplies are hairy devices; the panel is actually a memory device and the power supply produces a high voltage AC waveform to make that work.  Those panels normally light up around the rim; the fact you see that briefly but not sustained gives some hope that adjusting may be all that is needed.

That's quite a display; the usual plasma panels were 8 inches square, 512 by 512 pixels.  I'm guessing this is a 1k by 1k pixel display, which I have seen once or twice, at SAI in San Diego in some military displays.

I know a plasma terminal expert; I've forwarded your message to him.
