The Palm Pilot surely wasn’t the point of the TikTok, but it seemed to be the only thing anybody noticed. Ahead of the release of Oppenheimer, the official IMAX TikTok account posted a video showing the mind-bending size of the 70mm film print and the orange extensions IMAX had to build just to hold the platter in place. To give you some context: Oppenheimer’s film reportedly weighs 600 pounds, and the reel is an outrageous 11 miles long. Director Christopher Nolan told Collider that he thinks he might have hit the “outer limit” for how big a film reel can be.

But anyway, back to the Palm Pilot. Right there, in the foreground of the TikTok video, is a small blue and silver Palm device. (It’s technically not called a Palm Pilot — PalmPilot was the name of the company and devices long before the m130 came out — but everybody calls this class of devices Palm Pilots. So we will, too.) More specifically: a picture of a Palm Pilot, on a tablet, mounted to a white column next to the machine holding the reels. It’s not just a Palm Pilot; it’s a Palm Pilot emulator, running on another device because that’s apparently how important this thing is to getting Oppenheimer on a screen near you.

The emulated device in question is a Palm m130, a device released in 2002. It had a two-inch 160 x 160 display, was powered by Motorola’s 33MHz DragonBall VZ processor, and ran on Palm OS 4.1. Palm said the battery would last a week between charges, and you could even add Bluetooth via a card slot. People liked it, it got good reviews. You probably haven’t thought about it in damn near two decades.

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 fro
