My old 800XL is toasted from an electric power surge. I believe the OS chip is toasted. With your mapping, I am confident to start my journey to repair it. What other things should I consider looking at? It doesn't turn on at all (not even the led).

Very nice! They are great machines. Yours here has the Stackpole keyboard, FYI. There are five different keyboards variants for the 800XL's. Lucky that yours has BASIC rev C.

Thank you for the article. I am also just getting back into Atari computing. I still have my Atari 800XL bought from Dixons with a 1050 disk drive back in the early 90's. I have bought a Meanwell 5V 15W substitute PSU for the 800XL as the original is about 30 years old.

Incidentally, the 6502C processor is Atari specific and designated Sally. It has a HALT line which a normal 6502 CPU does not so they are not interchangeble.

Atari Age has an article on the S-Video modification for the 800XL at https://atariage.com/forums/topic/41580-quick-easy-video-upgrade-for-800xl/#comments.

I have not tried this yet as I have been upgrading memory on my Atari 65XE as lots of programs require 320KB, especially if you look for them!
