Every collecting hobby has its unicorns — pieces so scarce or historically strange that finding one feels like uncovering a genuine piece of lost history rather than just another purchase. Arcade collecting has several, and the stories behind why they’re rare are often as interesting as the games themselves.
Sinistar
Williams’ 1983 release Sinistar is remembered as much for its genuinely intimidating digitized voice — booming lines like “I am Sinistar!” and “Run, coward!” through the cabinet’s speaker — as for its demanding, resource-management-meets-shooter gameplay. The digitized speech technology and more complex hardware required to produce it made Sinistar more expensive and complicated to manufacture than a typical golden-age shooter, contributing to a shorter production run and its lasting reputation as one of the more distinctive and sought-after cabinets from Williams’ catalog.
Discs of Tron
While the original Tron (1982) shipped in a fairly standard upright cabinet and remains reasonably available today, Discs of Tron — its sequel and companion game — was also released in a dramatically different, dedicated sit-down “cockpit” cabinet: an enclosed, environmental unit that surrounded the player with speakers and lighting effects for a genuinely immersive experience unlike almost anything else on arcade floors at the time. Only a relatively small number of the cockpit-style cabinets were produced compared to a standard upright, making surviving, working examples a genuine centerpiece find for serious collectors specifically because of that unusual cabinet format.
Radar Scope and the Birth of Donkey Kong
One of the best-documented stories in arcade history involves a rarity created by commercial failure. Nintendo’s 1980 shooter Radar Scope flopped hard in the American market, leaving Nintendo’s U.S. division sitting on a warehouse full of unsold cabinets it had already imported. Rather than eat the loss, the company repurposed those existing cabinets with entirely new internal boards and artwork for an unproven new game from a young designer named Shigeru Miyamoto — Donkey Kong. Original, unconverted Radar Scope cabinets that survived that repurposing wave are now genuinely rare specifically because so many were cannibalized into becoming a completely different, much more successful game.
Cinematronics Vector Rarities
Cinematronics, a smaller manufacturer working primarily in vector graphics technology, produced titles like Cosmic Chasm in genuinely limited quantities compared to the major manufacturers’ output. Combined with the specialized vector monitor hardware these games require — harder to source and service than standard raster CRTs — surviving, functional examples are both rare and more technically demanding to keep running than more common golden-age raster titles.
Buying Rare Boards and Cabinets: What to Actually Check
- Verify chip labels and board layout against known reference photos before paying a rarity premium — bootleg and reproduction boards exist for exactly the titles collectors chase hardest.
- Ask for serial numbers and provenance where possible, especially for cabinets claimed to be original rather than converted from another title.
- Confirm the cabinet’s format matches the claim — a Discs of Tron in a standard upright shell rather than the dedicated cockpit cabinet is a meaningfully different, and less valuable, find, even with an authentic board inside.
- Budget for specialized restoration knowledge on vector-based rarities specifically, since their monitor technology differs from the more commonly serviced raster CRT chassis.
Chasing genuine rarities is a different game entirely from general collecting — it rewards patience, real technical diligence, and a willingness to travel or wait years for the right piece to surface, but there’s nothing quite like the moment a documented rarity actually lands in your garage.
