This Atari 800XL computer was originally featured on Adrian’s Digital Basement on July 29, 2023. In that video, Adrian diagnosed the issue, discovered a faulty ANTIC chip, and performed a chroma luma S-Video mod for improved video output. Now it’s my turn to revive this iconic 8-bit machine!
In this video, I install the missing C021697 NTSC ANTIC chip, attempt to reverse the yellowing on the 800XL’s lower case with a retrobright restoration, and get this classic Atari computer ready for its new owner.
Fun Fact: There are four versions of the Atari ANTIC graphics chip:
- C012296 (NTSC): Atari 400, 800, 1200XL
- C014887 (PAL/SECAM): Atari 400, 800
- C021697 (NTSC): Atari 600XL, 800XL, XE
- C021698 (PAL/SECAM): Atari XL, XE
If you're into vintage Atari repairs, retro computing mods, or just love seeing classic systems brought back to life, this one's for you!
DISCLAIMER: Please do not take this video as a tutorial / advice. I'm not an expert, this is just my hobby :)
