ARC ARC — Arcade Archive
Huge archive of arcade manuals, schematics, parts docs, and MAME material.
Arcade schematics. This comes up a lot on Tristan’s live streams.
ARC ARC (hosted on XMission) is a massive reference archive for arcade machine repair: PDF manuals and schematics organized by manufacturer (Atari, Bally/Midway, Nintendo, Williams) and by subsystem (monitors, coin mechs, DIP switches and pinouts, LaserDisc games, jukeboxes, slot machines), plus MAME material, ROM hacks, kits and hacks, magazines, and archived arcade websites. Still actively updated. The go-to when restoring a cabinet.
