Hello everyone, first poster here.

I'm lucky enough to put my hands on a GridCase 1530, with red plasma gas monitor (640x400); a truly beautiful machine.

While I want to use and preserve the original hardware, I want also to explore the feasibility of piloting the original display with a generic modern VGA output.
I'm asking for advice on identifying my version of the display (I understand both VGA and CGA versions exists), and if anyone could point me in the right direction for identifying the pinout.

Thank you!
