This is a vectrex logic PCB adapted to run on an arcade vector monitor (a 15V2000 Wells Gardner Vector monitor from a cabaret battlezone originally but running in an asteroids cabaret).
Now there are still a couple of issues.
1: there's a ripple visible on the vectors. I think it may be a ground issue but I can't track it down.
2: there's something not quite right with the text. The vectrex creates text by drawing 7 lines and adjusting the Z off and on as the beam travels along. It's a bit like how a TV image is created. But the issue is the beam looks like it's not turning on quite fast enough ?? so long dashes are bright but short dashes appear to dim. Don't know why that's happening.
