This Atari 800XL computer was recently featured on Adrian's Digital Basement. Adrian did some troubleshooting, found a bad ANTIC chip, then did the chroma luma S-Video mode. Let's install the missing ANTIC chip and see if I can revive the yellowed Atari 800XL computer case bottom, then it will be ready for it's new owner.
