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

I'm not sure exactly what you're asking, and I probably don't know the answer anyway, but I felt compelled to add a safety warning for anyone working with these.

The CRTs themselves can hold a high voltage for a long time, please be very very careful.
