I am an apple noob pretty much prior to Performa's, and that's not saying a lot- I recently happened upon an apple ][ with what I believe is a Rev I board in it, (#7850). This card was in it,(unmarked), along with a third-party disk controller card. I have no idea what this card is, as I wouldn't know most all other cards either. It has 1 male and one female RCA plugs, (cables), and the IC chip is marked "8545." Video/graphics? 80 column? (The CPU does not have an RF Mod in it, so...)
Any help would be appreciated. Jim
Unknown Apple ][ expansion card... Video/Graphics?
