I recently got an Apple II+ with a clone of the Saturn 128 memory card installed. I have it connected via composite video out to a modern LCD TV. With the memory card installed, there is a lot of red and blue color bleed around text on the screen, and a bunch of vertical blue dashed lines that are continually pulsating. Without the memory card, the text is crystal clear. Interestingly, whenever I load a program on disk, the bad text and vertical lines clear up while the disk drive is running, then come back.

Bad:

Good (while disk is running):

Is there any way to fix this? Should I find an official Apple 64k upgrade card and replace the clone Saturn card? Do I even need a memory upgrade? Im guessing yes because a lot of the games Id want to play probably require 64k.
