Wireframe 3D graphics like this did exist in 1983. It’s why it’s a visual aesthetic of that time period; it was the cutting edge of technology. The glow effect could be accomplished at that time by printing the rendered wireframe on a transparent sheet, then backlighting it and photographing it. That’s how they did the glowing effects in each frame of footage in the original TRON, which also showcases cutting edge 3D graphics from this time period.
