I recently got a bunch of old 80’s crts which I cant find any information about online.

I do have the service manual tho link
Looks like standart composite with external Horizontal and Vertical Sync to me but I’m not 100% sure and I dont want to fry anything
Thanks,
Oha


VGA might be a good idea. Do you think that these are just regular 640x480 displays? Can I damage them with a wrong resolution?
