The purpose of this page is to serve as a reference for most of everything regarding what was used on the few cabinets released by Rock-Ola.
The "rarity factor" only serves as a basis in contrast to every other game in this list. The lower the number, the more often it or something relating to it was seen.
It is unclear whether or not this game was put into production. Many production parts were printed and found when they were liquidating their warehouse.
It seems as if this game was withheld to become a conversion kit, like Levers, but never actually happened. No cabinets have surfaced, only parts.
This game was apparently very limited release. Cabinets were found, but had been converted. I own a prototype marquee similar in style to Survival and Levers.
Production marquees were produced.
Around this time Rock-Ola had quite a lot of parts stock from other machines such as Jump Bug, Warp Warp, Fantasy and Pioneer Balloon. Rock-Ola had the game developers write new games for existing hardware to utilize what they already had. Nibbler is the first of those games, and many are repurposed Fantasy cabs, and in very rare cases Pioneer Balloon cabs with blue artwork. It is speculated blue Nibblers used a blue/orange CPO.
Levers was technically unreleased. Rock-Ola's games division closed up as they were finishing Levers up for release. As they disbanded, all the parts were liquidated from the warehouse.
Only one conversion kit is currently known to exist, in a Warp Warp cabinet.
This game was reportedly sent to Rock-Ola to be reviewed for a licensing agreement by the developer (who also developed Eyes) shortly before their videogames division was closed.
Had the deal gone through and Gorkans was to be produced by Rock-Ola, it would have likely seen the same treatment as Levers and sold primarily as a conversion kit for Eyes. However, Luis Sanchez released it himself as a conversion kit for Pac-Man cabinets shortly after the Rock-Ola deal fell through.
QB-3 was demoed at the 1982 AMOA along with Rocket Racer. It was alleged that QB-3 was finished, but the Sound and Score ROMs are considered lost. Two QB-3 Main PCBs are known to exist.
One cabinet in the typical Rock-Ola style was found, though naturally converted. It could have been either QB-3 or Rocket Racer.
The other game demoed at the 1982 AMOA show, this one sticking to the typical B/W cinematronics monitor used in Demon, Armor Attack, and Star Castle.
This game is still lost and only a production marquee has surfaced.
