The Best IMAX Movies Still Need a Palm Pilot To Work

Ahead of the Oppenheimer release, IMAX's TikTok showed the massive 70mm film print and special IMAX extensions. The video interestingly featured an emulated Palm m130, commonly known as a Palm Pilot, a 2002 device running on a Motorola 33MHz DragonBall VZ processor and Palm OS 4.1. From a report: In an IMAX theater, the m130's job is to control the quick turn reel unit, or QTRU for short. (For many years, it appears, a non-emulated m130 sat holstered in most theaters.) The QTRU's job is to control the platters, which are those large horizontal shelves where all of a film's many reels are stitched together, stored, and then quickly spun out to and from the projector. The IMAX 1570 projector moves film at a little under six feet per second, so it's all happening really fast. The m130 is apparently crucial to keeping the thing humming -- "PALM PILOT MUST BE ON ALL THE TIME," reads a notice above an image of a different m130 that has since been passed around the internet -- but doesn't often need to be used. "I've never had to interact with the Palm Pilot," says one person familiar with the technology. "It's really just a status screen." Its job is to keep the QTRU moving at a consistent speed and to help keep the film's video in sync with its audio.
