Comet Pinball (Williams) System 9 – Rom Upgrade Chip Set

For those of you that cannot burn your own roms, these are the chips needed to upgrade your Comet pinball machine to the latest version, play a different version, or replace missing/damaged roms.
Bally Williams Part #’s:
COMET CPU GAME ROM1 U20: A-5343-10840

The default configuration is for sound roms to be burned on 2732 size roms. If your game has been configured differently, the sound roms can also be burned on 2532’s instead. Please make sure you are ordering the correct roms for your machine, or you will need to change jumpers. Per Pinwiki.com, “Only the early Space Shuttles use 2532 EPROMs from the factory. Later Shuttles, Sorcerer and Comet use 2732 EPROMs.”)
