Oooh! It just might be! (c) 1984!

I do have the extended 80-column card, but it's (c) 1981. Can it still
have Double Hi-Res?
I can't find J1 anywhere. I can only find J8 - J19 on the main board, and
no J's on the card. Also, a book I have said you could hook up pins 50 and
55, or something, and it would work.
By the way, what is J19? It doesn't have anything hooked up to it and it
isn't labeled. It has 2 pins. Is this for a fan?
