C011299 2 pieces 810 disk drive ROM $10
C014599 3 pieces 800 US OS ROM $15
Basically it's $5 per chip, but I won't break the packages up. They come in original Atari Service packaging, although the labels have come unglued, and the C014599 set originally had 4, but one was cut off and used, so it's only three ICs.
Will ship to anywhere.
