Comment on Question about driving some 80's CRTs

Heres a picture of the entire Board in case that helps:

A3.2 and B2.1 in the manual show you the pinouts of that jack and the expected signal, unfortunately section 6.1 schematics and sec D timing diagrams seem to be missing. You’re going to need to find a suitable driver circuit. Without looking at the timing it might accept input from an old MDA adaptor.p or similar.

Forgot to reply but I got another scan of the manual that includes these scans from the person that gave me the crts. i.ohaa.xyz/raw/oRiMLv.pdf
