NTSC composite artifact color is something typically relegated to computers with off-the-shelf graphics hardware. We associate it with the Apple II mainly, which used it in its high resolution modes. TRS-80 Color Computer fans also know it very well, because it was the only color available in that computer line's graphics until the Model 3. IBM PCs also used with more frequency than was commonly known in the early days in CGA graphics cards. But Commodore didn't rely on off-the-shelf 74-series logic to drive its home computers' displays. It had bought the MOS company and all its chip fabrication expertise. Its computers used real graphics chips and they displayed real color. They didn't need the composite tricks to get their graphics working and they didn't need boards devoted to graphics either. But I have come across some information which suggests that the assumption that the Commodore 64 did not support composite artifact color may not be supportable.

Gaslighting a Historical Event? - Billy Mitchell and His Perfect Pac-Man Game
On
July 3, 1999, Billy Mitchell made history by playing the first
verified perfect game of Pac-Man. This was major news at the
time and Mitchell was celebrated for his achievement. He not
only became something of a celebrity in the video game world but also
helped to raise the visibility of Walter Day's Twin Galaxies, an
entity devoted to keeping records of high scores and other video game
achievements. For nearly twenty years that achievement was generally
accepted and unchallenged. Recent developments, however, have called
this historical event into question. Allegations of cheating by
Mitchell have caused Twin Galaxies and Guinness World Records to no
longer recognize his achievement.
We
will discuss the game, give an overview of Mitchell and Twin
Galaxies, recount the story behind the event and the incidents which
gave rise to allegations of cheating and the effect they have had on
high scores and records of the past.
